Abstract

The invention relates to an oil cooling temperature control system for a driving motor bench test and a control method thereof. An oil outlet of an oil tank is sequentially connected with a circulating oil pump, a heat exchanger and a motor oil inlet connecting pipe; an oil cavity of a test motor used for being connected with the motor oil inlet connecting pipe is connected with a pressure release valve. The input end of the pumpback pump is used for being connected with an oil outlet of the test motor, and the output end of the pumpback pump is connected with an oil return opening of the oil tank. The control module is connected with the circulating oil pump and the pumpback pump so as to control the operation frequency of the circulating oil pump and the pumpback pump, so that oil liquid accumulated in the oil tank and the oil cavity of the test motor due to the pressure release valve can be very little by controlling the operation frequency of the circulating oil pump and the pumpback pump, the oil liquid can be efficiently recycled, and the test efficiency is improved. Therefore, the problem that the testing precision of the rack is affected due to the increase of the torque testing value of the motor when oil is accumulated in the oil cavity of the testing motor is solved.
