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 15):
The method according to  claim 13 , wherein\n the permanent magnet unit is incorporated to be used in a rotating machine, and has a length direction (x direction) dimension extending in a direction moving across a magnetic field of the rotating machine, a height direction (z direction) dimension vertical to the length direction and parallel to an axial direction of the rotating machine, and a thickness direction (y direction) dimension vertical to the length direction and the height direction, the step of determining the magnitude of the eddy current comprises, for a cross section at a position z in the height direction of the permanent magnet, calculating a magnitude Je (z) of an eddy current in the height direction vertical to the cross section using the following formula, [ Mathematical \ue89e \ue89e 6 ] J e \ue8a0 ( z ) = 1 T \ue89e \u222b T \ue89e \u222b S \ue89e \uf603 J z \ue8a0 ( r , t ) \uf604 \ue89e dSdT wherein r represents a position vector, t represents time, Jz (r, t) represents an eddy current density vector component in the height direction at the position z of a permanent magnet, S represents a cross-sectional area of the cross section at the position z of the permanent magnet, and T represents one period of an electrical angle, and\n the Nth insulating layer is located on a cross section vertical to the height direction at a position where Je (z) becomes in a range of values which is 95% of the maximum to the maximum.
