Abstract

The present invention discloses a method of testing a motor driving system. The method comprises the steps of carrying out the sweep frequency vibration test on the tested motor driving system installed on a vibration test bed in a first direction and according to a first vibration mode, and continuing a first preset duration; after the sweep frequency vibration test is finished, testing a preset parameter of the tested motor driving system according to a preset standard, and determining the state of the motor driving system according to a test result. By carrying out the vibration test on the motor driving system, the faults caused by the vibration of the motor driving system during a loading operation process are conducive to being exposed as soon as possible, thereby shortening the test duration of the system, and facilitating improving the reliability of the system.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a method for testing a motor drive system. Background technique [0002] The vehicle motor drive system is an important part of the electric vehicle powertrain system, and it is also one of the core components of the electric vehicle. The reliability of the vehicle motor drive system has also received more and more attention from scientific research institutions and production enterprises. The rapid completion of the reliability test of the motor drive system in the laboratory or production workshop helps to quickly expose potential faults or defects in the motor drive system, which not only helps to shorten the product development and marketing cycle, but also facilitates Improve the reliability of the product itself. [0003] However, the time required for the existing method for testing the vehicle motor drive system to complete the entire test process is too long, and it is ...
