ある。2. Description of the Related Art A rotor in which a permanent magnet of a permanent magnet type generator is arranged on the outer periphery is used, and as the permanent magnet, a magnet made of ferrite has been widely used in recent years. This permanent magnet is made of ferrite, and has the disadvantage that the corners around the permanent magnet are easily damaged during the fixing work of fixing the permanent magnet to the rotor core. Therefore, simplification has conventionally been a problem in the method of attaching, positioning, holding, and fixing the permanent magnet. For example, as a fixing method, a method of bonding an adhesive to a permanent magnet, or a method of arranging a permanent magnet on the outer periphery of a rotor and winding a metal winding or a glass tape on the outer periphery to fix the permanent magnet. And so on. Further, after the permanent magnets are provided, the whole is covered with a synthetic resin and molded. However, in recent years, the speed of rotating machines such as electric motors has been increased, so that the centrifugal force of the rotor has increased and the strength of holding and fixing the permanent magnet has become a problem. Furthermore,
In terms of performance, the gap between the rotor and the stator is important.
In particular, the displacement of the magnet in the direction of the rotation axis also affected the efficiency. For example, in a method described in Japanese Utility Model Laid-Open Publication No. Sho 62-172268, when a permanent magnet is fixed to a rotor with a permanent magnet, a positioning ring is disposed outside a shaft (rotating shaft), and the permanent magnet is fixed by the positioning ring. Is fixed to a rotor, a reinforcing wire is wound around the outer periphery of the rotor, and the outside thereof is fixed with a resin to fix a permanent magnet.

を固定する永久磁石付回転子を提供する。According to the above-described conventional method of fixing a permanent magnet to the outer periphery of a rotor core, a reinforcing wire is wound around the outer peripheral surface, and a resin is applied to the surface and heated. The steps of finishing the surface, such as melting and hardening the resin, are complicated. Further, when the permanent magnet is fixed on the outer periphery of the rotor core, the permanent magnet is brittle, and may collide with a protrusion of the rotor core, causing a corner portion to be lost, or a gap may be generated due to the loss. It has been difficult to accurately fix and hold so as not to shift. Since the permanent magnet is made of ferrite, when the permanent magnet is brought into contact with the protrusion on the outer peripheral surface, the permanent magnet is broken and a corner portion is lost. . Therefore, it is difficult to manufacture a rotor with a permanent magnet that fixes the permanent magnet in a fixed position due to the displacement of the permanent magnet during taping work of a metal tape or a resin tape on the outer peripheral surface of the permanent magnet. It was unsuitable as a rotating rotor. In particular, when a resin tape is wound, beads and the like often occur on the outer peripheral surface during heat curing. In the fixing method of these conventional methods, in terms of performance, the presence of metal-based protrusions or beads between the permanent magnets on the outer periphery causes magnetic leakage, and is not preferable in terms of magnetic efficiency. Further, the conventional rotor core is fragile against contact and impact, and it has been an important issue to position and fix the permanent magnet on the core. The present invention improves such a complicated fixing method and provides a rotor with a permanent magnet for fixing a permanent magnet to a rotor core by a simple method.
