【発明が解決しようとする課題】
このような従来の構成では組立工程が複雑で、コスト高になる。この課題の解決には２個のマグネットを１個にして、一回で外側と内側の両方を着磁できればよい。しかしながらこの場合、通常の工程で筒状ロータの外周側と内周側とを同時に着磁すると、ロータ外周面は、図８（ｂ）のような矩形波１００の着磁波形となる。このため、図８（ｂ）に図示するように最大値に幅ｗをもつ着磁がなされると、ＡＣ同期モータのロータ１０１の回転起動性能が損なわれ滑らかな回転は期し難い。また、ロータ１０１の回転が滑らかでないと、内蔵する磁気誘導機構も機能に影響を受ける。 0003
[Problems to be Solved by the Invention]
In such a conventional configuration, the assembly process is complicated and the cost is high. To solve this problem, it is sufficient to combine two magnets into one and magnetize both the outside and the inside at one time. However, in this case, when the outer peripheral side and the inner peripheral side of the tubular rotor are magnetized at the same time in a normal process, the outer peripheral surface of the rotor becomes a magnetized waveform of a rectangular wave 100 as shown in FIG. 8B. Therefore, when magnetism with a width w at the maximum value is performed as shown in FIG. 8B , the rotation starting performance of the rotor 101 of the AC synchronous motor is impaired, and smooth rotation is difficult to expect. Further, if the rotation of the rotor 101 is not smooth, the built-in magnetic induction mechanism is also affected by the function.

先ず図１および図２に基づいて、本発明に係わるモータの構成を説明する。ロータ１１がステータ１５（図２参照）に対向して電磁作用で回転駆動されるＡＣ同期モータ１０とその駆動力を出力軸１６に伝達する減速歯車輪列１２、ならびにロータ１１に連動して回転し、差動クラッチを構成する遊星歯車機構１７の作動を切り換えて出力軸１６を制御する磁気誘導回転体１３を含み増速歯車輪列１４を連設する構成体は、ケース１８に収納され、外部からＡＣ同期モータ１０に電源を投入する端子１９を備える。また、出力軸１６はレバー３０（図２参照）で外部と接続される。 First, the configuration of the motor according to the present invention will be described with reference to FIGS. 1 and 2. The rotor 11 rotates in conjunction with the AC synchronous motor 10 which is driven to rotate by electromagnetic action facing the stator 15 (see FIG. 2), the reduction gear train wheel 12 which transmits the driving force to the output shaft 16, and the rotor 11. The configuration in which the speed-increasing wheel train wheel 14 is continuously provided, including the magnetic induction rotating body 13 that switches the operation of the planetary gear mechanism 17 constituting the differential clutch to control the output shaft 16, is housed in the case 18. A terminal 19 for turning on the power to the AC synchronous motor 10 from the outside is provided. Further, the output shaft 16 is connected to the outside by a lever 30 (see FIG. 2).
