There are many kinds of motors, and the common motors are mainly power motors (DC motors, AC motors, AC/DC motors) and control motors (servo motors, stepper motors, torque motors, etc.). According to the regulations "GB755-2008 rotary motor rating and performance" and "GB14711-2006 small and medium-sized rotary motor safety requirements", the main tests include: electrical safety performance test (insulation resistance test, AC/DC withstand voltage test and turn-to-turn impact withstand voltage test), cold DC resistance measurement, load characteristic test, no-load characteristic test, blocking test, efficiency measurement, torque test, vibration and noise measurement, etc.

The main instruments involved in motor testing include: motor stator comprehensive tester, electronic rotor comprehensive tester, motor machine comprehensive tester, electrical safety performance tester, DC resistance measuring instrument, power analyzer, temperature measuring instrument, dynamometer, vibration tester and noise measuring instrument, AC power supply, DC power supply, etc.
