This increases the heating from eddy current flowing in the steel. If I had to do that, I would be looking for some insulating material in an angle iron format to put between the clamp strap and the corners of the lamination stack. Something wide enough to stay in position, but narrow enough to not impede the heats escape route into the air. Cheers, Gene Heskett You could always put a layer of inner-tube rubber between the motor and the mounting hardware. (You knew those leaky old bicycle tubes would come in handy didn't you) ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
