Motor Electrical Performance Testing
Electrical performance tests mainly include temperature rise test, no-load test, load test, maximum and minimum torque test, starting torque and starting current test, etc. The main purpose of these tests is to examine the thermal rating, output capability, service life, and adaptability of the tested motor under abnormal working conditions.
Input-Output Characteristics Test: Operating voltage range, 30-minute continuous torque, continuous power, peak torque, peak power, maximum operating speed, drive motor system efficiency, control accuracy, locked-rotor torque, regenerative braking characteristics.
Safety Test: Potential equalization, protection functions, DC bus capacitor discharge time.
Adaptability Test under Abnormal Working Conditions: Overvoltage test, overcurrent test, over-torque test, lightning surge test, cycle drop test, etc.
Durability Test: Performance durability test.
