The traction machine test bench is a testing device for evaluating the overall performance indicators of the traction machine. It measures 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. This 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 and noise
