This equipment is very common in industrial over the world.It use in many equipment and machinery.It make the processing more easier to handling.

In general,PLC  is a collection of electronic device which are in  place to ensure the stability,accuracy and smooth transition of a process or manufacturing activity.The relay,timer,counter,preset counter and many more control device built in this device.We can integrate with many output device  like motor,solenoid,heater,lamp,buzzer and etc.

We can use the software to create the wiring control design.it very easy and just use the symbol or icon in the diagram,we can control anythings.The software are depend on manufacturing of PLC likes mitsubishi ( GX-Developer ),Keyence ( KV Builder ),OMRON ( Syswin ),SEIMENS ( Mirco win ),LG ( KGL WIN ) and etc.I will discuss about PLC SOFTWARE more in my next post :D read more

A soft starter has different characteristics to the other starting methods. It has thyristors in the main circuit, and the motor voltage is regulated with a printed circuit board.It can control the current flow to motor more efficient and stability.

The soft starter makes use of the fact that when the motor voltage is low during start, the starting current and starting torque is also low.This type of motor starting is common used for air-condition and chiller system because it can reduce starting current in rush and can made a compressor more life span.

Calculation of motor capacity

05/10/2010 by Leave a Comment

Electric motor is the one of common device for rotating equipment and it’s useful for smooth operation and make our process more faster and efficiency.

But we must remember,we should sizing the motor capacity properly and must suitable with load,system and application for our process.

We can connect the electric motor with several types of mechanical load with gearbox,pulley,timing chain and etc.Proper calculation is must to avoid overload,bearing damage and motor burn due to wrong estimation about load. read more
