Directly drive formula magnetic coupling type harmonic motor

Directly drive formula magnetic coupling type harmonic motor belongs to the formula of directly driving motor field. The problem of motor on the current electric automobile gear transmission system all is hard to safeguard, output efficiency is low and the vibration noise reaches the conventionality greatly directly to drive formula the size of the electric machine huge is solved. The utility model discloses in the radial direction of rotor output shaft, from interior to exterior overlaps in proper order has the internal stator, cup -shaped rotor, external stator and casing, has the air gap between cup -shaped rotor and internal stator and external stator, left end lid and right -hand member lid approximately close respectively on the face of the left and right both ends of casing, and therim of a cup of cup -shaped rotor is towards right -hand member lid, the bottom of cup and the rotor output shaft fixed connection of cup -shaped rotor, all offered magnet steel slot along the axialon the inside and outside
