why we use electrically insulated bearing - china

This will help determine the best corrective action to implement if excessive shaft current is present Larger motors (generally 400 frame size and up: 404/405T) with excessive shaft current may need the additional protection from an insulated bearing or installing a shaft grounding ring at each bearing or using iPro extra capacity rings 2011-3-12Hello forum members We are in the process of ordering one 1 200 kW 5 5 kV wound electric motor to drive a rock crusher Is it essential that the non drive bearing should be an insulated one?Though I know that for VFD application insulated bearing on NDE side is compulsory The crusher would not be driven by a VFD
