Abstract: The hardware and software design of motor performance test platform based on virtual instrument and LabVIEW is introduced in this paper. The overall performance of motor can be evaluated by this platform through collecting and processing the signals of voltage,three-phase current,power factor,temperature,rotation speed and torque. Hardware of the platform consists of signal collecting,signal conditioning and signal processing modules,among which the circuit of signal conditioning is composed of current-voltage conversion module,voltage amplifying module,current source module and frequency-voltage conversion module. The signal processing is implemented by using NI-PCI 6221. The software is designed based on LabVIEW by using signal selection control toolbox,active data conversion control toolbox and display control toolbox,which respectively carry out signal collecting and selecting,signal processing and display. PID control is employed to carry out rotation speed and torque control. Tests show that this design has achieved desired effects. It is an innovative attempt in the field of motor test and control.
