The frequency conversion motor factory reminds that for the three-phase asynchronous motor products, it is a frequency conversion speed motor. Because the frequency conversion motor works at different speeds, and the speed difference is large, the motor manufacturers need to be cautious in the selection of the bearings of the frequency conversion speed control motor.

　　Because the variable-frequency speed-regulating motor will have shaft current and fever during use, which will affect the invariance of the variable-frequency motor bearing system, it is very important for the variable-frequency motor manufacturer to select the bearing of the variable-frequency motor.

　　In order to realize the bearing operation at higher than the reference speed, the inverter motor manufacturer can use a lubrication system that can accurately measure the amount of lubricant to reduce the friction of the bearing; or through the cycle oil lubrication system, the heat sink on the bearing seat or directly use the airflow Cooling takes away the heat.

　　Inverter motor manufacturers can invent the process of dissecting the bearing fever motor. When there is too much or too little grease, the city will have bearing fever. Regarding this problem, the layout of the bearing system is critical. The size of the oil cavity and the physical space deployment are very important. How to make effective and useful lubricants to the maximum extent is the prerequisite to guarantee the normal operation of the bearing system.It can be invented from the mechanism of heat conduction and the different heat transfer function of the medium. Grease is unlucky to deal with bearing heat. Excessive grease filling in the too large oil cavity in the bearing system often causes severe fever in the motor bearing.
