Problems solved by technology

The notching process is quite slow, and when winding pre-grooved laminations, there is difficulty in aligning the pre-punched slots
And the winding is difficult to wind, the slot full rate is very low
Therefore, the axial magnetic field disc motor has the problem that the iron core is difficult to manufacture

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] see figure 1 , 2 , 3. The present invention includes two stators 1 and a rotor disc 3, and the rotor disc is located between the two stators. The stator 1 is composed of a stator yoke 11 and an armature tooth 12. The stator yoke 11 adopts the traditional lamination method and is formed by laminating silicon steel sheets in the axial direction, and the armature tooth 12 is made of soft magnetic composite material (SMC). , the stator winding is wound on the armature teeth, and then fixed on the stator yoke. The rotor disk 3 is made of non-magnetic material, and the permanent magnets 4 are evenly embedded in the rotor disk, the direction of the magnetic poles of the permanent magnets is parallel to the axial direction, and the polarities of adjacent magnetic poles of the permanent magnets are opposite.

[0014] Such as figure 1 As shown...

Abstract

The invention discloses a double stator disk motor without a rotor yoke. The motor comprises two stators and a rotor disk, wherein the rotor disk is located between the two stators; the stators comprise stator yokes and armature teeth; the stator yokes are formed by axially laminating silicon steel sheets in the traditional lamination manner; the armature teeth are made of a soft magnetic composite; stator windings are arranged on the armature teeth in a winding manner, and then fixed on the stator yokes; the rotor disk is made of a non-magnetic material; permanent magnets are uniformly embedded into the rotor disk; directions of magnetic pole of the permanent magnets are parallel to an axial direction; and the adjacent magnetic poles of the permanent magnets are opposite in polarity. The motor is simple in structure, easy to manufacture and high in space filling factor, has a lower tooth slot torque and is applicable to driving of electric vehicles and ships.

Description

technical field [0001] The invention relates to the field of special motors, in particular to a rotorless yoke double-stator disc motor. Background technique [0002] Compared with the traditional radial field motor, when the number of poles of the motor is large enough and the ratio of the axial length to the outer diameter is small enough, the axial field permanent magnet motor has obvious advantages in terms of efficiency and unit output torque. In addition, the axial field motor also has the advantages of compact structure, small moment of inertia, and good heat dissipation conditions of the stator winding. It can be made into a multi-stator, multi-rotor multi-air gap structure to increase output power. Axial field disc motors are therefore particularly suitable for direct drive of electric vehicles and ships. [0003] In order to obtain a high unit output torque without increasing the thickness of the permanent magnet, the armature core of the axial magnetic field disc...
