摘要: The invention discloses a built-in alternative-pole permanent-magnet motor based on rotor complementary structure. In the motor, permanent magnet pole S (7), N (8) and an iron core (9) are respectively disposed in first (2), second (3) third (4) heteropolar mode. three-rotor structure is nested stator (1),and coaxial with (1). (1) comprises armature teeth (5) fault-tolerant (6), wherein (6) alternately arranged alongthe periphery of provided winding (10), (10) wound mode single-layer fractional-slot centralized winding. Compared multi-stator distributed winding, simple reliable, low cost, has no magnetic circuit coupling, small copper loss, high efficiency. Because just one end part torque power density high.
