Claims

[Scope of Claim for Utility Model Registration] 1. In a permanent magnet field type rotor in which fan-shaped laminated magnetic pole cores and rectangular permanent magnets are arranged alternately in the circumferential direction, a through hole is provided in the magnetic pole core and the rotating shaft is A non-magnetic support body integrally formed with end plates on both sides to be inserted and supported and a connecting part that passes through the through hole of the magnetic pole core and connects the end plates to each other, and a magnet is inserted into at least one of the end plates. 1. A permanent magnet field type rotor, characterized in that a permanent magnet is provided with a hole and is inserted and fixed from the axial direction between the magnetic pole iron cores from the magnet insertion hole. 2. In a permanent magnet field type rotor in which fan-shaped laminated magnetic pole cores and rectangular permanent magnets are arranged alternately in the circumferential direction, a wedge-shaped notch that opens on the rotating shaft side is provided in the magnetic pole core, and the rotating shaft is an annular portion surrounding the
A non-magnetic support body is provided on the outer periphery of the annular portion and is integrally formed with a radial wedge that fits into the notch of the magnetic pole core, and the magnetic pole core that is fitted into the wedge from the axial direction and between the magnetic pole cores are provided. A permanent magnet field rotor characterized by having a permanent magnet inserted and fixed in the rotor.
