The traction machine test bench is a testing device for evaluating the whole machine performance indicators of a 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. This test bench can meet the performance testing requirements for various types of traction machines, providing accurate parameter indicators for assessing the manufacturing, maintenance, and field application of traction machines.

Test Parameters:

Input voltage Uab, Ubc, Uac - Voltage unbalance

Input current 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.
