The traction machine test bench is a testing device for detecting the overall performance indicators of traction machines. 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. The test 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 voltage Uab, Ubc, Uac - Voltage unbalance

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, noise, etc.
