Dc motor controller consists of two parts, the stator and rotor, can realize direct current (dc) and mechanical energy conversion to each other. Only in use will have bearing damage problem, below small make up the way the cause of bearing damage. 1. Caused by different types of oil mixture; 2. Caused by itself manufacturing quality problems; 3. Because the standby is not running for a long time, make the oil metamorphism caused; 4. Because of the dislocation, rotor core axial or renewed after rotor machining precision is not enough; 5. Because of the bearing cavity is not clean or not clean grease.
