BRUSHLESS MOTOR AND MOTOR DRIVE CONTROLLER
PROBLEM TO BE SOLVED: To provide a small-sized brushless motor that has high holding power under suspension and that facilitates control under the suspension, and an inexpensive motor drive controller that facilitates control.SOLUTION: In a brushless motor, holding windings VA1-VA4 are wound around teeth T2, T5, T8 and T11, around which V-phase drive windings V1-V4 are wound, respectively, together with the drive windings V1-V4. When a driving current to the drive windings V1-V4 is interrupted, a direct current is passed through the holding windings VA1-VA4.
【課題】小型で停止時の保持力が大きく、停止時の制御が容易なブラシレスモータ及び制御が容易で安価なモータ駆動制御装置を提供する。【解決手段】ブラシレスモータは、Ｖ相の駆動巻線Ｖ１〜Ｖ４がそれぞれ巻回されたティースＴ２，Ｔ５，Ｔ８，Ｔ１１に、駆動巻線Ｖ１〜Ｖ４とともに保持巻線ＶＡ１〜ＶＡ４を巻回した。そして、駆動巻線Ｖ１〜Ｖ４への駆動電流を遮断したとき、保持巻線ＶＡ１〜ＶＡ４に直流電流を流す。【選択図】図４
