Application of Programmable Logic Controller in Medium and Small Motor Test

Introduction was made to the application of measurement system developed by adoption of programmable logic controller (PLC) in motor feature test. After the transfer of parameters collected by the system, via PID closed-loop control to make the motor to be tested working in preset test conditions, and finally forming the parameters and test reports needed. The system testing state is stable, to have raised correctness and validity of measurement, reduced measurement system error as well as test personnel’s labor strength.
