NU244EM-C3-J20C Bearing What is the insulating layer of the electrically insulating bearing? At present, most of the insulating bearings are coated with ceramic or resin materials on the steel ferrule, cage (or copper), the rolling elements are made of ceramic materials, and the insulating bearings coated with ceramic are insulated. , anti-creep, heat dissipation performance has an advantage. All ceramic insulated bearings are less expensive due to their high price. Generally, how many motors use insulated bearings depends on the power state of the motor. Normal grid power supply does not have high-frequency voltage and current components, generally does not use insulated bearings, only high-voltage motor large motors such as 400 or more specifications are used. You can even use it. However, now the variable frequency power supply, because the power quality contains a lot of high-frequency components, resulting in increased motor shaft current, so the specification should be considered in more than 400 specifications, even smaller specifications are also considered to be installed according to the use of insulation Bearings, such as electric vehicles, electric rail locomotives and other main motors are generally about 100KW, and must use insulated bearings (or other insulation structure to ensure that the shaft current does not flow).
