A programmable logic controller ( PLCS ) is a general-purpose device. PIC microcontrollers are a very useful and versatile tool for use in many electronic projects. controlling the essential parameters of the distribution transformers using the system based on microcontroller. In this example, we’ll be controlling one of Teknic’s ClearPath brushless DC servo motors (Important: This is for the SK and HP line of ClearPath Motors only). In this article we are discussing about the difference between AVR, ARM, 8051 and PIC Microcontrollers. To protect small range motors(2HP to 200HP) contactor module is used and for large motors.
