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： Having a stator core including a yoke, a plurality of inside teeth, and a plurality of outside teeth, an inside rotor, and an output rotor, the inside slot open angle/inside pole angle and the outside slot open angle/outside pole angle are determined so that the inside cogging torque due to rotation of the inside rotor and the outside cogging torque due to rotation of the outside rotor may cancel each other in inverted phases. Plural combinations are provided so that the amplitude of inside cogging torque and the amplitude of outside cogging torque due to rotation of outside rotor maybe approximate values in inverted phase, and the combination of the highest combined voltage value of the both induced voltage is selected.
