Embodiment Construction

[0027] It should be noted that the "circumferential", "axial" and "radial" mentioned in the present invention all refer to the circumferential direction of the stator yoke, the axial direction of the stator yoke, and the radial direction of the stator yoke. The "circumferential", "axial" and "radial" definitions of the motor stator yoke are the same.

[0028] Such as figure 1 , figure 2 As shown, the motor proposed in the embodiment of the present invention is an axial flux motor. In the figure, the direction X represents the axial direction, and the direction Y represents the radial direction. The motor includes: two rotors 4, two sets of stator teeth 2 and two stator yokes 1, the two rotors 4 are arranged along the axial direction, two sets of stator teeth 2 are arranged between the two rotors 4, and are connected to the adjacent There is a gap between the rotors 4 and they are radially symmetrical. The rotor 4 is covered with a winding 3. The two stator yokes 1 and the t...

Abstract

The invention discloses a motor convenient to produce and process, and the motor comprises two rotors arranged in the axial direction, two groups of stator teeth arranged between the two rotors, and two stator yokes, wherein the two stator yokes are arranged between the two groups of stator teeth, and one stator yoke is corresponding to one group of stator teeth. According to the invention, the two stator yokes are communicated with each other and are in one-to-one correspondence with each group of stator teeth, thereby avoiding a mode that one stator yoke simultaneously corresponds to two groups of stator teeth, and reducing the thickness of the stator yoke. As the stator yoke is formed by punching a plurality of stator yoke punching sheets, the production difficulty of the stator yoke can be greatly reduced by reducing the required thickness of the stator yoke, thereby reducing the production and processing cost and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a motor that is convenient for production and processing. Background technique [0002] With the guidance of the government's energy-saving policy and the needs of market development, the direct current of household appliances fans has gradually become a trend. At present, the brushless motors used in the industry are of radial magnetic field structure (that is, the magnetic field is distributed radially along the rotor) and the power density of the motor is low. That is, the material Low utilization. Affected by the rising market price of motor raw materials, high power density motors have become the development trend of brushless DC motors. Axial flux motors are gradually being popularized and applied due to their performance advantages. Although the axial flux motor has the characteristics of high efficiency and high power density, in the combination of multi-stator and mu...
