MOTOR

To reduce noise and vibration.SOLUTION: In a motor that produces different magnetic resistance between one and the other of magnetic poles, a stator coil includes two sets of three-phase coils that are individually supplied with current. Coils U1, U2, V1, V2, W1, and W2 of each of phases of the two sets of three-phase coils are symmetrically arranged with an electrical angle of 180° as a boundary. Through a coil corresponding to each of the two sets of three-phase coils, a fundamental wave component of the same period is passed, and the current value of each of the phase coils of two sets of three-phase stator coils is set according to the electromagnetic force generated by the difference in the magnetic resistances of the magnetic poles.SELECTED DRAWING: Figure 2 【課題】騒音・振動を低減する。【解決手段】磁極の一方と他方とで磁気抵抗が異なる状態を生じるモータであって、ステータコイルは、個別に電流が供給される２セットの３相コイルを含む。２セットの３相コイルの各々の相のコイルＵ１，Ｕ２，Ｖ１，Ｖ２，Ｗ１，Ｗ２は、電気角１８０°を境にして対称に配置され、２セットの各３相コイルで対応するコイルには、同じ周期の基本波成分が流されるとともに、各磁極の磁気抵抗の異なりによって発生する電磁力に応じて、２セットの３相ステータコイルの各相コイルの電流値が設定される。【選択図】図２
