C3VL0241 Ceramic Insulated Bearing

Even if the production of the motor is strictly controlled during the manufacturing process, it is difficult to completely avoid the magnetic asymmetry of the armature and rotor. This asymmetry creates a voltage between the stators, which creates a current through the bearings, especially in AC motors. This current will cause corrosion pits, melting marks, electrical corrosion file lines and discoloration, wear and other damage on the bearing raceway and rolling surface. Of course, this phenomenon will also appear in the use of frequency conversion and frequency conversion technology on the motor. In order to block the current flowing through the bearing, it is necessary to cut off its circuit, so the insulated bearing and the insulated bearing chamber came into being.
