In large permanent magnet motors, the permanent magnet in the motor is segmented into parts in order to reduce the eddy current loss in permanent magnet. It is reported that the insulation between sintered Nd-Fe-B magnets is possible only by contacting the segmented permanent magnets without insulation. But the mechanism for such a phenomenon has not been clear. We have already reported that the analysis...
