Motor temperature rise testing device

The utility model relates to a motor temperature rise testing device. According to the device, the control module is electrically connected with the control end of the frequency converter, the resistance measurement module, the temperature measurement module and the control end of the switching module, and the state change of the frequency converter and the switching module is controlled by utilizing the driving function of a first electric signal and a second electric signal output by the control module; the automatic measurement of the cold-state winding resistance when the motor to be measured is not started and the environment temperature when the test is started can be realized, the automatic measurement of the hot-state winding resistance after the operation of the motor is finished and the environment temperature after the operation of the motor is finished can be realized, and the temperature rise of the motor can be further calculated according to the acquired environment temperature and the resistan
