摘要： A motor includes a stator which includes a stator core having an annular stator yoke, a plurality of outer teeth projecting outward from the stator yoke and a plurality of inner teeth projecting inward from the stator yoke, and a plurality of windings wound on the stator core. The motor also includes an outer rotor confronting the outer teeth with an air gap therebetween and an inner rotor confronting the inner teeth with an air gap therebetween. This motor thus has twin-rotor. The stator core includes outer slots between each one of the outer teeth as well as inner slots between each one of the inner teeth, and the windings are wound on the stator yoke between the outer slot and the inner slot. A cross sectional cut of the stator reveals that a sectional area of the outer slot is equal to that of the inner slot.

摘要： A clutch mechanism moving together with an actuator allows coupling or decoupling an inner rotor to or from a power shaft, thereby controlling a rotation angle. This structure allows a polarity of a magnetic pole of the inner rotor to be the same as that of an opposing magnetic pole of an outer rotor when the motor is driven at a low rpm, so that magnetic fluxes inter-linking with windings can be increased, which results in greater torque. When the motor is driven at a high rpm, the structure allows the polarity of the magnetic pole of the inner rotor to be different from that of the opposing magnetic pole of the outer rotor, so that an amount of leakage flux is increased, and the magnetic fluxes inter-linking with the winding are decreased. As a result, an induction voltage is lowered and a high rpm range is widened.
摘要翻译：与致动器一起移动的离合器机构允许将内转子与动力轴联接或解耦，由此控制旋转角度。当电动机以低转速驱动时，该结构允许内转子的磁极的极性与外转子的相对磁极的极性相同，使得可以增加与绕组相互联系的磁通量，这导致更大的扭矩。当电动机以高转速驱动时，该结构允许内转子的磁极的极性与外转子的相对磁极的极性不同，使得漏磁通量增加，与绕组相互连接的磁通量减少。结果，感应电压降低，高转速范围变宽。
