Motor Test Bench

Motor Test Stand (Motor Test Stand):

The motor test bench is used to test and display the voltage (DC or AC), current (DC or AC), input power, output torque (rated torque, locked rotor torque, starting torque, maximum torque), speed, output power, and efficiency of the motor. Temperature, vibration, noise, etc. It can conduct type tests, factory tests, and performance tests to evaluate the comprehensive performance of motors, providing accurate and precise basis for the research and development, production, and repair of motors. The motor test bench can test various types of asynchronous motors, synchronous motors, permanent magnet motors, AC motors, DC motors, new energy vehicle motors, marine propulsion motors, etc. The motor test bench (motor test bench) consists of the tested motor, speed and torque sensors, current sensors, voltage sensors, temperature sensors, vibration and noise sensors, controllable analog loads (electric dynamometer, eddy current dynamometer, hysteresis dynamometer, etc.), cast iron installation platform, fixtures, couplings, electric control cabinet, computer data acquisition real-time control system intelligent electrical parameter measuring instrument (or power analyzer), motor testing software, MAP efficiency cloud map, etc.
