Problems solved by technology

However, in general, the parameters of the reactor load cannot be changed during the test process, so only the ability of the drive device to carry a fixed load cannot be tested, and the load dynamic change test cannot be performed. In actual application scenarios, the load of the motor will vary with the process requirements. while dynamic changes

Abstract

The invention provides a test system and a test method of a driving device. The test system of the driving device comprises a controller, a test end motor and a twin-trawling motor; the controller is respectively connected with a driving device to be tested and the twin-trawling motor; the test end motor is connected with the driving device; an output shaft of the test end motor is connected with an output shaft of the twin-trawling motor; the controller sends a driving instruction to the driving device, so that the driving device controls the test end motor to rotate according to the driving instruction; and the controller drives the twin-trawling motor to rotate, so that the twin-trawling motor outputs variable torque through the output shaft to change the load of the driving device. Through the test system provided by the scheme, the dynamic load test can be carried out on the driving device.

Description

technical field [0001] The present application relates to the field of electromechanical technology, in particular to a testing system and testing method for a driving device. Background technique [0002] The driving device of the motor is used to control the motor to rotate according to the required speed and torque. Whether the driving device can work normally is directly related to whether the motor can rotate according to the demand. Therefore, after replacing the new driving device or repairing the driving device, it is necessary The device is tested. [0003] In the prior art, the driving device is connected to the reactor load, and the change of the output current during the process of driving the motor is simulated through the reactor load, so as to perform a load test on the driving device. However, in general, the parameters of the reactor load cannot be changed during the test process, so only the ability of the drive device to carry a fixed load cannot be teste...
