摘要： The invention relates to a motor comprising a stator core having plural teeth and slots provided among the teeth, a winding applied on the teeth by a single turn, and a rotor incorporating plural permanent magnets, which is rotated and driven by utilizing reluctance torque in addition to magnet torque. By turning thus divided teeth by a single winding, the occupation rate of the winding in the slots can be raised. As a result, a motor of small size and large output can be presented.

摘要： A motor comprises a stator core having plural teeth and slots provided among the teeth, a winding applied on the teeth by a turn, and a rotor incorporating plural permanent magnets. The rotor is rotated and driven by utilizing reluctance torque in addition to magnetic torque. Since the winding is not crossed, the size of the coil end is reduced.

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： An electric motor is equipped with a rotor having multiple rows of slits arranged along a radial direction. A permanent magnet is buried only in some of the slits, namely the ones closest to the center of the rotor or the innermost slits, to drive the motor using both magnet torque and reluctance torque. This improves the torque output.

摘要： This invention pertains to a rotor core (6) in which a plurality of core sheets (1) are laminated on one another on a rotor shaft (4). A plurality of slits (3, 7) and a plurality of strips (2) are alternately arranged in a radial direction of each of the core sheets (1) so as to convexly confront a center of each of the core sheets (1) such that an outer peripheral rim (10) is formed between an outer peripheral edge of each of the core sheets (1) and each of opposite ends of each of the slits (3, 7). A stress concentration portion (11) which is provided at a portion (10a) of the outer peripheral rim (10) and has a width (L1) larger than that of the remaining portions of the outer peripheral rim (10).
