Claims

[Scope of utility model registration request]

(1) In a device whose magnetic poles are a plurality of permanent magnets disposed and fixed on the outer periphery of the rotor, grooves in the recesses of the plurality of dovetails are opened in the direction of the outer circumferential axis of the laminated rotor core, and An arc-shaped permanent magnet end is provided with a pair of trapezoidal protruding ends, and a cup-shaped and slit gap is provided between the protruding ends, and a groove in a dovetail recess provided on the outer periphery of the laminated rotor core is opened. A cup-shaped gap is formed in the axial direction by inserting the magnet into the cup-shaped gap, and an arc-shaped permanent magnet is fixed by inserting an hour-shaped wedge made of non-magnetic material into the hour-shaped gap. Permanent magnet rotating electric machine.

(2) The axially intermediate part of the laminated rotor core is provided with an intermediate laminated rotor core in which punched rotor iron plates are laminated in a cavity whose inner diameter is larger than the diameter of the rotor shaft, and the laminated rotor core at both ends is The iron core is characterized by laminating rotor iron plates with punched rotor shaft holes on the inner diameter to fit into the rotor shaft, and sandwiching the above-mentioned intermediate laminated rotor iron core and inserting it into the rotor shaft. A permanent magnet type rotating electrical machine according to claim 1 of the utility model registration claim.
