Japanese Patent JP2019068729
Kind Code:
A
Abstract:
To achieve structural completeness of a rotor component.SOLUTION: The present invention provides a structure of a permanent magnet rotor assembly including a plurality of magnetic poles and containing a plurality of magnetization pieces 30 arranged in a circular array. Two pairs of a permanent magnet and one pair 50 magnetized to a peripheral direction of a rotor and a second pair 40 that supplies a magnetic flux to an axial direction of the rotor are focused through a magnetic pole piece, and generate the magnetic flux mutually operated with the magnetic flux of a stator. An end plate 60 formed by a magnetic material exist so as to have a gap in the axial direction between arrays of the magnetic pole pieces. A magnet magnetized to the peripheral direction is arranged to a peripheral direction gap between the magnetic pole pieces, and the magnet supplying the magnetic flux in the axial direction is arranged in the gap between the array of the magnetic pole piece and the end plate.SELECTED DRAWING: Figure 1a
