electrical_motor

Various Types of Electric Motors

Permanent Magnet Motors

In a synchronous machine that is magnetized by permanent magnets composed of neodymium boron iron, or ferrite on the rotor, or samarium cobalt. They are placed on the surface of the rotor core in some motors because across the gap the magnetic field is radially directed. You can find its application in variable speed drives were from a variable frequency the stator is supplied, electronically controlled by source. It is designed for operating at a speed that is synchronous with a stable supply of voltage and frequency. There are no means of controlling the stator power factor over there.

electrical_motor

Hysteresis Motors

With respect to the supply frequency, the speed is uniquely related and it is one of the rarest features of synchronous motors. There are lots of applications of for several special types of synchronous motors in devices like tape recorders, clocks, and photographs. The most frequently used motor is the hysteresis motor which is composed of a rotor with a ring of semi-permanent magnet material like a high-carbon steel. By pulling the rotor out of synchronism, the speed is reduced by the stator field which leads to the rotor material to be magnetized. Good starting torque is provided by these motors with low ripple and is very silent. It has low efficiency and only small power ratings applications are permitted.

Reluctance Motors

Iron poles are caused to hold a magnetic flux for aligning with each other that forced by the Reluctance motors to work on this principle. There is no electrical windings and has four iron poles. There are six poles in the stator with a current carrying coil in each. Similar to an induction motor, the stator is made and has a controllable supply with three phase. Isolated by non-magnetic spacers, the rotors include longitudinal iron laminations. There are salient poles in the rotor without any field windings. You can also find a damper winding in the rotor surface that helps the machine to start the induction motor.

Single Phase Synchronous Motors

In synchronous motors, there is a chance of producing revolving field from a single phase source with the use of the same method and single-phase induction motors. To the main supply, the main stator winding is directly connected to an auxiliary winding and it can be connected through a capacitor. In combination with hysteresis type rotor, the shaded-pole construction of the stator is widely used for small clock motors. It has a very low efficiency which is less than 2 percent.

Direct Current Commutator Motors

Across the rotor by poles on the stator, a stationary magnetic field is produced. With the help of field coils, these poles may be encircled carrying direct current or may have permanent magnets. There is an iron core with a coil accommodated in slots of the rotor or armature. To the bars of the commutator switch kept on the rotor shaft the coil is also connected. They are highly used in paper mills, steel mills, robots, and machine tools where speed reversal or speed control is required.

Alternating Current Commutator Motors

From a single phase alternating voltage supply, a specially designed series commutator motor can be worked. During the time when the supply current reverses both the armature and the magnetic field are reversed. They have huge application in small domestic appliances like mixers, vacuum cleaners, and portable tools.

Autocad_Course

What is the need for electrical CAD software for electrical documentation?

Either electrical CAD software or AutoCAD is used by the electrical professionals for the purpose of constructions. Here the main focus is about the advantages and disadvantages of using two types of CAD software for electrical related work.

Autocad_Course

If you are planning to make a hole in the wall then wall drill is used and for making a hole on the board, a wood bit is used. It is possible to use the wood bit instead of wall drill or wall drill instead of the wood bit but then the process would become tedious and the result will not be as expected.

The same metaphor can be used for constructional CAD software.

AutoCAD is the king

An internationally used construction CAD software is AutoCAD and it is for a good reason. It is considered as one of the renowned tools for construction drawings with many innovative functions for changing diameters, shaping, viewing details from various perspectives, etc. Thus AutoCAD software is right for you when this is the main requirement.

Electrical documentation and AutoCAD

Although it is designed for creating electrical documentation in AutoCAD, it is possible to do it

These are the things you can do:

Electrical symbols can be designed- but the required intelligence cannot be added to them

Ordering lists can be drawn- but there is no possibility of filling them automatically

You can write texts- there are no means of automatic translation.

Relay coils and contractors can be placed- there are no means of automatic updating of references

In the software, the basic workflow is designed for construction work. With the addition of electrical functions on top the construction core, and thus the workflow would be time-consuming. A mediocre result would be given by combining constructional functions with electrical CAD.

Electrical Professionals lack AutoCAD training

AutoCAD software is not something handy with the electrical professionals. Therefore creating electrical documentation using AutoCAD there is a need for an extra individual to create it based on the rough sketches from the electrical professionals.
Electrical professionals are seldom experienced AutoCAD users. Using AutoCAD for electrical documentation therefore requires an extra person to create the documentation based on sketches from the electrical professionals. This involves communication back and forth between the persons involved – including the misunderstandings this might bring.

The importance of Electrical CAD software

While developing electrical documentation, there is a need for various other intelligent functions.

You need functions like:

Automatic wire numbering

Reference designations

Intelligent copying

Support of electrical standards

Automatic update of parts lists and connection lists

Copying easily in and between projects

Assistance for installing correct drawing

Signal references between pages

Communication with PLC I/O tools

In between symbol references

Creating and sending ordering files automatically

Connecting lines and automatic drawings

Foreign country business demands automatic translation of texts in drawings, and the skill to choose the type of text to translate.

Component databases -major time saving

The diagram symbols are intelligent in the electrical CAD software. For the component they represent, they have an article number apart from that the component’s electrical connection points can be identified and handled with cleverness by the software.

The software can be used automatically by attaching these types of information to a component.

This is the following work flow:

You will get electrical symbols of this component in the pick menu if you choose a component from one of these databases.

Article data are transferred automatically to the diagrams if you place these symbols on the diagrams.
Without the requirement of typing, any component information at all is possible thus the software can fill out all types of lists automatically.
The symbols have the same article has the originals when you copy these symbols in the diagrams.
It saves lots of time.

Electrical and Mechanical CAD Integration

Both AutoCAD and an electrical CAD software can be used at the same time. For instance, just create a drawing plan in the AutoCAD and after completing it you just need to insert it in the OLE object.

On the top of the AutoCAD file, in the electrical CAD software PSCHEMATIC Automation, you can draw the electrical drawings. In the PSCHEMATIC Automation, the electrical information can then be stored. Directly from PSCHEMATIC, you can open it if you need to make any changes in the ground plan.

After completing the changes, just get back to the normal working mode of PSCHEMATIC and include more electrical information to your PSCEHAMTIC drawing above the AutoCAD drawing.

Electrical_Inverter

EXPLAIN INVERTER AND ITS TYPES

In the 19th century one of the most talk of the town debate of battle was not in politics or with swords but for the type of electricity to be used by our buildings. For more information join the electrical training course to make your career in this field.

Electrical_Inverter

Distinguish between DC and AC electricity

Direct Current (DC) is the main talk over here especially when the science teachers taught the reason behind the electricity generation and it is called as the flow of electrons. It can be considered that electrons are like ants carrying packages of electricity. Switch, battery, lamp are linked by a circuit and the electrical energy is transported from the battery to the lamp till the energy in the battery is discharged.

But the situation is different in the bigger household appliances and the power supply coming along from the outlet is based on alternating current (AC) each and every second the electricity switches direction for 50 to 60 times. It is very difficult to understand how AC provides energy where there is a constant change in its mind about destination.

For instance if the electron runs from the outlet to a few millimeters down the cable then have to change the direction and go back again so the question is how the lamps gets light?

It is very easy to pin down the answer, just consider the cables in between lamp and the wall packed full of electrons. As you switch it on the vibration causes the electron to flow back and forth in the filament of the lamp. For transporting energy the electrons need not mandatory run in circles and in AC the simply run on the spot.

What is an inverter?

Most of the appliances is our house are made to run from the AC power. Devices that require DC but take AC from the outlets has a need of an extra piece called rectifier and it is built from electronic components known as diodes for converting from AC to DC.

It is quite easy for understanding the concept of how it works as the inverter works totally opposite of it. In a flashlight, if you are having a battery and the switch is on so there is a flow of DC around the circuit and it is always in the same direction. But if you change the position of the battery still the DC will flow in the opposite direction. If you are that fast in changing the position 50 to 60 times then you are acting as an inverter changing the battery from AC to DC at a frequency of 50 to 60 HZ.

Types of Inverter

If you switch on and off your DC current or change it back and forth as it is keeping on reversing the direction then you will end up with sudden changes of the current all in one direction and all in one direction back again. With respect to the current or voltage if you draw a chart against time and you may find getting a square wave. It can be considered an alternating current, technically. In general terms there are hefty appliances in our homes and all they want is energy and lots of it, so it doesn’t bother the square waves.

There are two types of inverters they are true/pure sine wave inverters and modified/quasi sine wave inverters. True inverters make use of transformers and electronic circuits to rapidly change and they can be used for powering any kind of AC appliance from a DC source which has computers, video games, TV, radios etc.

Modified sine wave inverters use thyristors diodes and other components for producing a rounded-off square wave and it is good for delivering power hefty electric appliances. Thus there is a risk of overheating with MSW inverters.

EXPLAIN PLC AND POLLING MODE!

A PLC & SCADA system in the industry is actually used for the machine control development. In architecture, the document explains the SCALA & PLC systems and their process interface hardware, application and functionality development facility offered by them.

automation_training

With respect to industrial standards there are some attentions required to which they attach their conspired evolution along with potential benefits for their use.

PLC An Overview

A PLC or Programmable Controller is used for the purpose of industrial automation process like machine control on factory assembly lines.

The PLC is made for lots of inputs and arrangements unlike normal computers, immune to electric noise, impact and vibration, large extended temperatures. Machine control operations for programming battery hacked stored or non-volatile memory.

Real time system’s example is PLC since there must be a production in output results in input conditions

A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

For the purpose of Supervisory Control and Acquisition of industrial process, SCADA is a widely used industry. For the purpose of experimental physics lab ancillary systems are controlled with ancillary systems like ventilation, cooling, power distributions etc.

The functional scalability of the substantial progress with respect to recent years are open, performed, scalable that are alternative to in house development for control systems that are complex and demanding as those in physics experiments.

How to choose a polling mode?

DF1 Half-Duplex Master

There can be a slave station communication configured with master station in either Message-based polling or Standard polling mode. Here are few pros and cons discussed below:

Message-Base Polling Mode

The best message based polling mode in communication networks with slave stations

Message-based polling mode is best used in networks when communication with the slave stations is not time critical and where the user needs to be able to limit when and how often the master station communicates with each slave station.
It is not recommended for larger systems that require time critical communication between the master and all the slave stations, or for systems where slave station-initiated messages are going to be used. Thus our electrical training course is more than enough for you to make your career in this field.

RELAY

EXPLAIN RELAY CIRCUIT SWITCH IN DETAIL!

A relative amount of power for operating the relay coil is the benefit of relay but there are various usage of relay in control motors, lamps, heaters, Ac circuits which use a lot of electrical power. For more information join the electrical training course to make your career in this field.

RELAY
An output device (actuator), electro-mechanical relay arrives in a lot of sizes, shapes, and designs. There are lots of applications, uses in electronic circuits. For reducing the electronic power or computer type circuits, electrical relays are used for switching relatively high voltages or currents for both ON or OFF state controlling, relay switch circuit is required.
The types and design of relay switching circuits is huge, but lots of tiny electronic projects utilizes MOSFETS and transistors. As the transistor can offer rapid DC switching (ON-OFF), it is used as main switching device. Let us see few relays over here.

NPN RELAY SWITCH CIRCUIT

A coil driven NPN transistor is a typical relay switch circuit relying on the input voltage level. The transistor is disconnected and acts as an open switch when the base voltage of the transistor is zero (or negative). There are no collector current flowing and the current devices causes the coil relay to be de energized and there will not be any current flow through the relay coil if there is no current flow in the base.

In the base if a positive current is drawn for NPN transistor saturation, the B to E current flow controls the larger relay coil passing through the transistor from the Collector to Emitter.

For the famous bipolar switching transistors, the flowing currant’s amount in the relay coil inside the collector between 50 to 800 times and for driving the transistor to saturation, the needed base current is made to flow. The beta value or the current gain of the general purpose BC109 is a 290 mA data sheet.

NPN DARLINGTON RELAY SWITCH CIRCUIT

For switching small loads like LEDs and miniature relays, the ancient NPN transistor relay circuit is very apt. For switching larger relay coils or currents crossing the threshold range of BC109 transistor can be achieved using Darlington Transistors.
The current gain and sensitivity of a relay switch circuit can increase greatly using a pair of transistors of Darlington. Two similarly connected Bipolar transistors can be shown into one device with standard: Emitter, Base, and Collector connecting leads.

The first transistor’s collector current TR1 becomes the base current of the second transistor TR2 because two NPN transistors are connected.

Darlington switching pair configured from two individual transistor have a small value resistor (100 to 1000 ohms) placed between the Emitter and Base of the main switching transistor, TR2 for ensuring the fully OFF turns. A flywheel diode again is used for protecting TR2 from the emf generated back during the relay coil DE-energizing.

EMITTER FOLLOWER RELAY SWITCH CIRCUIT

The Standard Common Emitter Configuration having a relay coil can be connected to Emitter terminal for forming an Emitter Follower Circuit. There is a direct connection of input signal directly to the base and the output is driven from the Emitter load.

EMITTER DARLINGTON RELAY SWITCH CIRCUIT

The Darlington transistor version of the ancient emitter follower circuit has TR1, a small positive base current causing a greater collector current to flow via TR2 because of multiplication of the two Beta values.

DEFINE PLC

For the automation of different electro-mechanical processes in industries a digital computer called Programmable Logic Controller (PLC) is used. For surviving during tough times these controllers are specially used and they are protected from cold, heat, dust, and moisture, etc. Computer Language is used for programming the microprocessor existing in the PLC.

It is a computer written program and is PLC down-loadable via cable. In the nonvolatile memory of PLC these loaded programs are stored. For the user fed program the hard wired logic was exchanged during the change from relay control panels to PLC. For controlling and programming the PLC, Ladder Logic, a visual programing language was created.

electricalplc

PLC HARDWARE

CPU, Memory, Input/Output, Power Supply Unit, and Programming device are the hardware components of a PLC system.

CPU– For avoiding the errors the PLC controller is checked. Logic Operations, computer interface, arithmetic operations are some of the performed functions.

Memory– CPU uses fixed data. In the operating system the data is permanently stored in the System (ROM). Status of Input and Output devices, values of timers, counters and other external device information are stored in RAM.

I/O section– Sensors, switches are field devices that are tracked by the input section.

O/P Section- Motors, lights, pumps, and solenoids are some of the devices Output has a a control on. Reduced Instruction Set Computer (RISC) is the basis for I/O ports.

Power Supply– An isolated power supply is available in certain PLC. You can find most of the PLCs working at 220VAC or 24VDC.

Programming device– Inside the memory of the processor, the device is used for feeding the program. First the programming device is fed with the program and the later forwarded to the PLC’s memory.

System Buses: The internal digital signal flows through the buses in the PLCS. The four system buses are:

  • For transferring data among different elements, data bus is used by the CPU.
  • With respect to the action that are controlled internally, control bus transfer signals are used.
  • Location’s address is sent using the Address Bus for accessing the data.
  • The I/O port and I/O unit communicates with each other using system bus.

As PLC has been into existence since 50 years there is a very meager need for improvement and thus if you are planning to work with PLC you can consider it as a mature technology. Any equipment has a competitive counterpart with a never ending need of improvement, providing faster, smaller and cheaper solutions.

In the world of industrial automation, the embedded processor of PLC is providing a real-time proprietary operating system is in demand today.

It is anticipated that there will be a need for improvement in hardware, software, and communication to develop with the adapting technology in the future of PLC. Programmable Automation Controller (PAC) and PLC functionality, will be evolved as a part of the evolution.

SMALLER, FASTER, BETTER

In the current electronics industry the circuit boards, components, and processors are shrinking. PLC is in need for stability, reliability, and slow acceptance for the improvements in its technology. For added memory capacity, improved cycle time, and new communication features with the help of fast processors are the current enhancements. Most of the higher end PLCs are converting to lower end PLCs with respect to market demands, functions, and features. For instance it can be considered that small PLCs will improve to have lots of features of PLCs with higher-end and mid and high range PLCs have very less to offer, and the user requirements are met with compact solutions.

PLC AND PAC COMBINATION

Lots of industrial controller suppliers show case the difference between PACs and PLC but the nomenclature is not taken care of by the future of automation engineers targeting on performance and the existing features when their system is specified. PACs and PLCs will keep on growing similar to features and definition of each of them is growing and changing.

There will be lots of demand for low and high-end processors during this transformation period. Who knows, the lower-end processors will make their way with advanced features as there is an advancement in hardware technology with passage of time.

For including more features and options pressure will be put on the suppliers for the above reason. The advanced features of motion control, vision system integration, and similar support for multiple communication controls with steady maintenance of the simplicity thereby making PLCs attractive to their customers.
