Motor performance test bench test system consists of test power supply, power switch screen cabinet, signal sensing device and power measurement equipment, automated test measurement unit and control console and AC motor test software system, database system and other components.
Measurement mode: using frequency conversion power analyzer measurement
Measuring cabinet is equipped with inverter power sensor, adopting front-end digital technology and fiber-optic transmission in the middle to transmit the digital signal to the digital host to complete the signal processing and display the real-time data, real-time waveform, harmonic analysis and other parameters.
Control mode: using the upper computer control
PC + host computer control mode, flexible control mode, can be customized according to user requirements, modification, control system performance is stable, good system scalability.
Operation mode: manual operation and automatic operation coexist.
In order to avoid the microcomputer failure to affect the test work, manual control (panel button operation) and automatic control (computer keyboard/mouse operation) coexist, inconvenient to use automatic control or microcomputer failure, you can use manual operation to test.
