The motor manufacturer reminds that, compared with ordinary motors, the bearing system of high-power motors is larger. It does not make much sense to talk about the insulation layout of high-power motors separately. It should start with the bearings, bearing sleeves, end caps, and end covers related to the insulation layout. Let's talk about related parts.

　　In the actual operation and utilization process of high-power motors, the most problematic is the noise of the bearing. This type of problem is probably related to the quality of the bearing itself, and on the other hand, it is related to the selection of the bearing. The problem is the insulation problems derived from the unsuitability and unfairness of the high-power motors in the use of working conditions.

　　Compared with ordinary motors, high-power motors, high-voltage motors and variable-frequency speed-regulating motors also face a shaft current problem. In order to solve this problem, on the one hand, insulated bearings can be recycled, but the purchase cost of such bearings is relatively high, and Some insulated bearings are still not popular; on the other hand, the recycling of grounding equipment, but this kind of maintenance is relatively poor.In view of this environment, motor manufacturers want to take steps on bearings and recycle insulated bearing sleeves. However, the processing of such insulated bearing sleeves is huge. The basic reason is to divide the bearing sleeves into two parts, and the bearing compartment department is insulated by insulation. The method of cutting off, so that the circuit of the shaft current caused by the shaft voltage is completely cut off, which is a once and for all method.
