石付回転子の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a rotor with permanent magnets in which permanent magnets are mounted on the outer periphery of the rotor yoke.

久磁石５が遠心力により回転子ヨーク４から脱落するの
を防ぐことび組立工程が繁雑になる欠点があった。In recent years, the start-up delay of industrial machinery has been remarkable, and as a result, small, high-output, high-efficiency electric motors have come to be used to drive them. The structure of a conventional electric motor of this type is explained with reference to FIG. 1, for example. 1 is a stator yoke around which a winding 2 is wound, and 3 is the outer peripheral surface of a rotor yoke 4 made of laminated steel plates. The rotor is made up of a permanent magnet 5 that is divided into two parts and is fixed to the rotor yoke 4 using an adhesive, and 6 is the rotor shaft. mt- As mentioned above, if there is a sudden start, sudden stop, or slow or high-speed rotation, the permanent magnet 5 may fall off from the rotor yoke 4 due to centrifugal force, or the permanent magnet 5 itself may break. As a result, there were drawbacks such as abnormal noises being generated and electric IT being unable to operate normally. In particular, in recent years, sintered magnets that can increase magnetic flux density are often used, and this magnet is weaker than conventional arconia magnets.
The above-mentioned drawbacks are noticeable. Additionally, as shown in Fig. 2, a method was developed in which a reinforcing band 7 made of non-magnetic material is completely wound around the outer circumference of the permanent magnet 5 in order to prevent the permanent magnet 5 from falling off or being agitated due to high-speed rotation of the rotor 3, etc. However, in this case, it is difficult to prevent the permanent magnet 5 from falling off the rotor yoke 4 due to centrifugal force, and the assembly process is complicated.

被覆して、永久磁石５の脱落を阻止する方法も考えられ
ているが、この構造では、永久磁石５の外周に巻回した
線材に含浸。Furthermore, a glass roving material impregnated with a synthetic resin is wound around the outer circumferential surface of the Mizuku trout stone 5, or a solid metal wire is wound around the outer circumferential surface of the Mizuku trout stone 5, and this wire and the permanent magnet 5 are made of synthetic resin. A method of preventing the permanent magnet 5 from falling off by coating the permanent magnet 5 has also been considered, but in this structure, the wire wound around the outer periphery of the permanent magnet 5 is impregnated.
塗布した合成樹脂の肉厚が均一にならず、合成樹脂の硬
化後、回転子３外側の樹脂を切削により均一な厚さにす
る必要があった。The thickness of the applied synthetic resin was not uniform, and after the synthetic resin had hardened, it was necessary to cut the resin on the outside of the rotor 3 to a uniform thickness.

供することにある。The present invention eliminates the above-mentioned drawbacks, prevents permanent magnets from falling off, etc. without using special members, etc., and prevents centrifugal force due to high-speed rotation of the rotor, sudden startup, etc. To provide a rotor with permanent magnets that can sufficiently withstand shocks caused by stopping, has a simple structure, and is easy to manufacture.

久磁石付回転子を得ることを特徴とする。In the present invention, a plurality of locking portions are integrally installed in the radial direction on the circumference of the rotor yoke at equal intervals to prevent the permanent magnets from falling off.
Between adjacent locking parts, a permanent magnet that is thicker than the rotor yoke and is locked across the adjacent locking parts is loosely fitted along the circumference of the rotor yoke. In the gap formed between the permanent magnet and the locking portion of the rotor yoke, a bonding layer of synthetic resin that joins both members is formed across both axial end surfaces of the rotor yoke. The permanent magnet is firmly fixed to the rotor yoke (by the wedge action of the bonding layer) to obtain a rotor with permanent magnets.
