Zhuzhou CRRC is mainly engaged in traction motors and transformers, generators and energy efficient motors R & D and manufacturing, are parts of wind power equipment in China's rail transportation, leading enterprise, product market share of more than 50%.
Zhuzhou CRRC motor traction motor of main national accredited laboratory traction power and power equipment engineering technology research work, the traction motor testing system for traction motor testing research test, using the electric energy feedback structure, the tested motor electric operation, dragging with motor power, with motor generates electricity accompanied by drag the end back to the inverter, inverter and drag to provide energy for the tested motor running in test-bed internal flow can realize power feedback during the operation of the external power grid only need to add the energy loss, greatly saves the operation cost.
