[0002] Brushless DC motor controllers need to undergo aging tests before leaving the factory to inspect product quality, find product defects, and eliminate unqualified products; traditional motor controller aging tests are carried out by motor-to-drag, and the two motors work separately. Motoring state and power generation state can simulate the working state of the controller under different load conditions of the motor, but this method is expensive and occupies a large area; the rotor of the brushless DC motor is removed, and the controller is directly connected to the stator for aging testing. A simple and effective method, but the feedback information of the rotor position needs to be obtained in the control of the brushless DC motor, and the complete motor control program cannot be realized by simply connecting the stator, so there is a big difference between the test process and the actual working state of the controller

The invention provides an aging testing device and method for a direct-current brushless motor controller. The aging testing device comprises an accelerator signal regulator, a hall signal generatingdevice, a motor controller, a power supply, a direct-current brushless motor and an upper computer. According to the device and the method, the defects that the cost is too high, the occupied area islarge, and the process is complex when the aging testing is carried out through a motor twin-dragging way at present are solved; and moreover, the hall signal generating device solves a problem that alarge difference exists between a state in a testing process and a state in actual work of the motor controller after the testing device is simplified.
