Plenty of Standard IEC/EN Symbols

The IEC/EN symbols for automation are achieved by the electrical CAD software you get and the hydraulics/pneumatics, installation and flow diagrams. Apart from that, you can find lots of symbols for sensors transducers, and PLCs, computer, telecommunication alarm installations etc along with ground plan drawings.

47 free component databases

There is a possibility for creating your own component databases in Automation. There are various leading component manufacturers along with an extra advantage that has created their own component databases with free electrical CAD for the software.

Beyond common component information- like component vendor, prices, descriptions, part number, etc and these databases comprise both mechanical and electrical symbols for the individual components.

There are database programs along with software that you c an get form PSCHEMATICs own database program. There are various major database systems in combination with Automation like MS-SQL and Oracle.

Thus a combined part of the database system is possible in the database of the company.

Automatic Update of all lists

You can get various component lists, terminal lists, cable lists, connection lists cables, etc. in the automation design of your own parts. Similar to the pages in projects the lists can be created and there is a user defined style which can be imported into other systems.



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.


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.

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.


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.

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.


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.
