Auxiliary Motor Test Bench, Traction Motor Test Bench

I. Purpose 

The auxiliary motor test bench is suitable for the idle maintenance operation of AC auxiliary motors in subway vehicles. It is used for the no-load running-in and no-load testing of three-phase AC asynchronous motors with a power of 40kW or less (with a rated voltage not exceeding 380V). It is equipped with a dedicated electrical parameter testing instrument to test the three-phase current, three-phase voltage, power, and power factor parameters of the motor. Additionally, it comes with a magnetic suction type temperature sensor to measure the working temperature of the auxiliary motor and the ambient temperature.
