Abstract

A direct-driving magnetic-coupling type harmonic motor relates to the field of direct-driving motor, and solves the problems of difficulty in maintenance, low output efficiency and big vibration noise of the prior motor-gear drive system of the electric automobile, and the huge volume of the conventional direct-driving type motor. An inner stator, a cup-shaped rotor, an outer stator and a shell are orderly sleeved from outside to inside on a radial direction of a rotor output shaft; an air gap is arranged between the cup-shaped rotor and the inner stator, and between the cup-shaped rotor and the outer stator; a left end cover and a right end cover separately cover on the left and right end faces of the shell; the opening of the cup-shaped rotor faces towards the right end cover; the bottom of the cup-shaped rotor is fixedly connected with the rotor output shaft; magnetic steel grooves are set on the inner and outer side walls along the axial direction; magnetic steels are embedded in the magnetic steel grooves; the number of magnetic pole pairs of a armature winding is Ps; the teeth number of each of the inner stator and the outer stator is Ns; the number of magnetic pole pairs on the wall surface of the cup-shaped rotor is Pr; and, Ns=Ps+Pr. The harmonic motor provided by the invention is mainly applied to the direct driving fields of electric automobiles, and so on.

Description

technical field [0001] The invention belongs to the field of direct drive motors. Background technique [0002] Since entering the 21st century, energy shortage has become an important problem restricting the development of various countries, and the development of new energy sources, energy saving and consumption reduction have become research hotspots in various countries. Because traditional fuel vehicles will emit exhaust gas, which will not only pollute the environment but also consume a lot of energy, countries have started research on hybrid vehicles and electric vehicles, and my country has invested a lot of manpower and material resources in the research on electric vehicles. to the forefront of the world. The drive motor is the power component of the electric vehicle and is an indispensable part of it. Although there are many types of electric vehicles available, most of them still use the cooperation of the mechanical deceleration system and the motor to complete ...
