Dear all,
Need your insight on a matter related to Non-Driven End and Driven End insulation of bearings. In most cases, various motor manufacturers recommend that NDE side should be insulated whereas DE side should not.
Logically, I see that whether DE or NDE insulation is there on the bearings, it serves the purpose. Moreover, we do not need insulated bearings in non-VFD driven motors. What do you say?
My specific inquiry is that why focus is given on using insulated bearings on NDE side only. Why not DE? Moreover, If I do have grounding brush on my shaft anywhere, does that play a part in this?
Regards,
Mutahir
