Abstract:
The present invention provides a permanent magnet unit in which insulating layers are located at positions where an eddy current can be reduced most effectively. The permanent magnet unit includes at least one insulating layer, and a plurality of permanent magnet pieces located adjacent to each other with the at least one insulating layer in between. The at least one insulating layer is located at positions defined based on a magnitude of an eddy current flowing inside a permanent magnet, corresponding to a change in a magnetic field of the permanent magnet into which a plurality of the permanent magnet pieces are integrally formed without the at least one insulating layer.

Claim (Index 12):
The method according to  claim 10 , wherein the step of determining the magnitude of the eddy current comprises, for any cross section of the permanent magnet, calculating a magnitude Je (\u03be) of an eddy current in a direction vertical to the cross section \u03be using the following formula, [ Mathematical \ue89e \ue89e 4 ] J e \ue8a0 ( \u03be ) = 1 T \ue89e \u222b T \ue89e \u222b S \ue89e \uf603 J S \ue8a0 ( r , t ) \uf604 \ue89e dSdT wherein r represents a position vector, t represents time, Js (r, t) represents an eddy current density vector component in a direction vertical to a cross section \u03be, in the cross section of the permanent magnet, S represents a cross-sectional area of the cross section \u03be of the permanent magnet, and T represents one period of an electrical angle.
