Motor temperature rise testing device, testing control method thereof and controller

The invention relates to a motor temperature rise testing device, a testing control method thereof and a controller. According to the motor temperature rise testing device, the controller is electrically connected with the control end of the frequency converter, the output end of the resistance measuring module, the output end of the temperature measuring module and the control end of the switching module, and the states of the frequency converter and the switching module are controlled in an automatic control mode. 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 automatically calculated according to the acquired environment temperature
