The traction machine testing bench is a test device for detecting the overall performance indicators of the traction machine. This device tests various performance parameters of the traction machine, including: input current, voltage, power factor, electrical power, output torque, speed, power, efficiency, temperature rise, vibration and noise, etc. The testing bench can meet the performance testing requirements for various types of traction machines, providing accurate parameter indicators for evaluating the manufacturing, maintenance, and field application of traction machines.

Test Parameters:

Input voltages Uab, Ubc, Uac - Voltage imbalance

Input currents Ia, Ib, Ic      Current imbalance

Power (P_in), Power Factor

Output Torque (T_out), Speed (n_out), Power (P_out)

Efficiency (η)

Temperature Rise (Δθ)

Vibration and noise
