The invention provides a magnet installation type rotor which is easy for installing a protective member for permanent magnets, and the protective member is not scratching the surface of the magnets in the process of installation. The magnet installation type rotor has a rotor core (2), permanent magnets (3) and a belt-shaped metal net (5) The rotor core consist of a plurality of armor plates which are laminated together to form a plurality of hook projection rows (1a) extending axially on the outer surface of rotor core. The laminated armor plates possess a plurality of radial hook projections (1a) along the circumferential direction on the outer periphery. The outer surfaces of the permanent magnets are convex surfaces and the bonding surfaces are concave surfaces on the outer periphery of the rotor core. The center part is thicker than the lateral part. The permanent magnets are bonded between hook projection rows on the outer peripheral surface of the rotor core. One side of the metal net is applied with tension and the other side of the metal net is wounded on the surfaces of permanent magnets (3), and the meshes are hooked by the hook projections. |
