    摘要： In a closed loop control method of a linear vibration actuator which vibrates linearly and energized by a switching element driven in a PWM control method, a crest or peak point (Bc, Bp) of the back electromotive force occurring in the linear vibration actuator is detected (S14). The detected crest or peak point (Bc, Bp) is compared with a reference value (Bcr, Bpr) (S15), and adjusting the PWM duty (α) applied to the switching element and controlling the operating frequency of the linear vibration actuator to resonant frequency (S16 to S19), thereby keeping the crest or peak point (Bc, Bp) of the back electromotive force always constant.

    摘要： A motor has a stator formed by assembling stator members in an annular shape. The stator member includes a core segment formed of laminated electromagnetic steel sheets, an electrical insulator covering the core segment, and a coil wound on a tooth of the core segment via the insulator. At least parts of the insulator contacting the coil is made of highly heat-conductive insulating resin. A motor has a stator iron core formed of laminated electromagnetic steel sheets, and the motor includes a highly heat-conductive insulating sheet disposed on the laminated face of a slot of the stator iron core and a coil wound in a slot via the sheet. These structures allow the heat generated by the coil to travel to the core segment with ease, because of the resin or the sheet disposed between the core segment and the coil, thereby cooling the motor efficiently. As a result, a continuous output rating is improved, and a highly efficient motor with long service life, free from shortening its service life due to the heat, can be realized.
