Title:
VIBRATION IMPACT TEST METHOD FOR PERMANENT MAGNETIC DIRECT-DRIVING MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/019300
Kind Code:
A1
Abstract:
A vibration impact test method for a permanent magnetic direct-driving motor, being achieved by use of a special vibration impact test platform. Traditional random vibration is replaced by rolling vibration, so that problems in the existing random vibration test platform of insufficient largest load, being unable to assess random vibration fatigue performance of a bearing and being unable to achieve impact working conditions are effectively resolved. The test shows that the method is precise and feasible, the operation process is simple, the result data is reliable, and the test cost is greatly reduced; the method is especially suitable for vibration impact test of the permanent magnetic direct-driving motor.
