Description
【０００１】[0001]
本考案は、界磁磁石回転型電動機の回転子に関する。 The present invention relates to a rotor of a field magnet rotary electric motor.
【０００２】[0002]
界磁磁石回転型電動機の回転子は、従来一般に図２に示すように、回転軸２１ の表面に設けた界磁磁石固定部２２に、界磁磁石２３を接着固定し、その外周に ロータカバー２５を装着して構成されている。 As shown in FIG. 2, a rotor of a field magnet rotary electric motor has a field magnet fixing portion 22 provided on the surface of a rotating shaft 21 and a field magnet 23 bonded and fixed to the rotor cover. 25 is mounted.
【０００３】[0003]
しかし従来の回転子は、界磁磁石２３に作用する遠心力を接着層２４で受け、 また機器の温度上昇と共に接着層２４の接着力が低下し、遠心力によって接着層 ２４が破壊して界磁磁石２３が飛散するといった欠点があるため、ロータカバー ２５を装着してこれを補助する必要がある。 本考案は、界磁磁石回転型電動機の回転子において、ロータカバーを無くし、 かつ回転子の遠心力に対する強度的信頼性を向上するものである。 However, in the conventional rotor, the adhesive layer 24 receives the centrifugal force acting on the field magnet 23, and the adhesive force of the adhesive layer 24 decreases as the temperature of the device rises. Since there is a drawback that the magnetic magnets 23 scatter, it is necessary to mount the rotor cover 25 to assist this. The present invention eliminates the rotor cover in the rotor of the field magnet rotary electric motor and improves the strength reliability of the rotor against the centrifugal force.
【０００４】[0004]
本考案においては、回転軸の界磁磁石固定部に、断面が台形状の界磁磁石固定 用の軸方向の溝を設け、界磁磁石をこの溝に嵌合すると同時に接着固定して回転 子を構成する。 In the present invention, the field magnet fixing portion of the rotating shaft is provided with an axial groove for fixing the field magnet having a trapezoidal cross section, and the field magnet is fitted into this groove and is fixed by adhesion at the same time. Make up.
【０００５】[0005]
上記のように構成された本考案の回転子においては、界磁磁石に作用する遠心 力を界磁磁石の側面と界磁磁石固定用の溝の側面で受ける構造となり、強固に界 磁磁石の固定が可能となる。 In the rotor of the present invention configured as described above, the side face of the field magnet and the side face of the groove for fixing the field magnet are structured to receive the centrifugal force acting on the field magnet. It can be fixed.
【０００６】[0006]
【実施例】 図１は、この考案による回転子の一例で、界磁磁石固定用の溝１２を回転軸１ １に軸方向に設け、界磁磁石１３を界磁磁石固定用の溝１２内に嵌合して接着固 定し、回転子を構成する。FIG. 1 shows an example of a rotor according to the present invention, in which a groove 12 for fixing a field magnet is axially provided on a rotary shaft 11 and a field magnet 13 is provided in the groove 12 for fixing a field magnet. Then, the rotor is constructed by fitting and fixing.
