Abstract

A permanent magnet type motor enabling a segment type magnets to be accurately and fixedly adhered to the outer peripheral surface of a rotor core. The permanent magnet type motor comprises a permanent magnet type rotor formed by fixedly adhering the plurality of segment type magnets (3a) to (3h), at intervals, onto the outer peripheral surface of the rotor core (2) fixedly fitted to the outer peripheral surface of a rotating shaft. V-shaped or U-shaped projections (4a) to (4h) are disposed on the outer peripheral surface of the rotor core (2) at positions between the segment type magnets (3a) to (3h). One side pieces of the projections (4a) to (4h) are formed as magnet support parts (4aa) to (4ha) in contact with one sides of the magnets without changing their shape, and the other side pieces are formed as magnet pressing parts (4ab) to (4hb) pressing the other sides of the magnets in the circumferential direction by pressurizing.
