作動する際に、回転子ユニット２００の第１電磁鋼板２０５及び固定子ユニット３００の第２電磁鋼板３０３は、連携して第１電磁鋼板２０５を第２電磁鋼板３０３の中央位置にフロートさせ、回転軸２０２の一端は、軸受け１０２を介して軸受け孔に支持されケーシング５００により制限され、リード線４００は、エンドカバー１０１から引き出される。固有頻度で電源の正負極を切り替える回路基板により給電を行い、リード線４００に接続されたコイル２０３は、電力を受けると電磁力を発生させ、固定子ユニット３００において絶縁部材２０１の両側に対応して設けられる磁石タイル３０１に対して偏向運動を行い、それによって、第１電磁鋼板２０５が２枚の第２電磁鋼板３０３の間の中央位置にフロートしないように駆動され、一側の第２電磁鋼板３０３が近づき、同極反発原理に基づいて、回転子ユニット２００及び第１電磁鋼板２０５がともに所定角度偏向したとき、第１電磁鋼板２０５及び第２電磁鋼板３０３の反発力がコイル２０３による電磁力に抗し、回転子ユニット２００は回転を止め、コイル２０３は、逆方向に電力を得ると、反対する運動を行う。 When operating, the first electromagnetic steel plate 205 of the rotor unit 200 and the second electromagnetic steel plate 303 of the stator unit 300 cooperate to float the first electromagnetic steel plate 205 to the central position of the second electromagnetic steel plate 303 and rotate.

When the steel plate 303 approaches and the rotor unit 200 and the first electromagnetic steel plate 205 are both deflected by a predetermined angle based on the homopolar repulsion principle, the repulsive force of the first electromagnetic steel plate 205 and the second electromagnetic steel plate 303 is generated by the coil 203. In opposition to the force, the rotor unit 200 stops rotating and the coil 203 carries out the opposite movement when it receives power in the opposite direction.
絶縁部材２０１は、絶縁ゴム部材とすることで、本モータの製造コストを低下させるだけでなく、応答速度を高め、振動周波数を向上させ、耐用年数を延ばす。 By using the insulating rubber member as the insulating member 201, not only the manufacturing cost of the motor is reduced, but also the response speed is increased, the vibration frequency is improved, and the service life is extended.
