Abstract
A testing system for testing a temperature characteristic of a first motor includes a second motor, a controller, a driver, a load, a temperature sensor, and a temperature recorder. The controller provides a drive command for the driver to drive the second motor. The second motor drives the first motor via a coupling. A current of the first motor is determined by adjusting the resistance of the load. The temperature sensor senses the temperatures of the first motor every a determined time and sends the temperatures to the temperature recorder. The temperature recorder records and transmits the temperatures to the controller for the temperature characteristic test of the first motor.
