Embodiment Construction

[0022] see figure 1 , figure 2 and image 3 , the present invention includes a rotating shaft 7 , a stator 1 , a rotor 2 and a winding 4 . In the middle is the rotating shaft 7, and the outer coaxial sleeve of the rotating shaft 7 has a stator 1 and a rotor 2. Among them, the stator 1 is composed of N s C-shaped stator blocks, N s A C-shaped stator block is evenly distributed along the circumferential direction outside the rotating shaft 7, and the angle between two adjacent C-shaped stator blocks is 360 / N s The axial section of each C-shaped stator block is C-shaped, and the C-shaped openings are all facing the inner end, facing the rotating shaft 7. Each C-shaped stator block is made of laminated silicon steel sheets.

[0023] see Figure 4 , the width of each part of the C-shaped stator block is equal. The inner space of each C-shaped stator block forms a stator slot 1-1, and the axial sides of the stator slot 1-1 are two stator teeth 1-2, and each stator tooth 1-2...

Abstract

The invention discloses an axial flux switch reluctance motor for reducing noise. A stator is composed of Ns C-shaped stator blocks uniformly distributed along a circumference direction out of a rotating shaft, the axial section of each C-shaped stator block is C-shaped with an opening towards the rotating shaft, an internal space of each C-shaped stator block forms a stator slot, and a winding iswound on each stator tooth; a rotor is composed of Nr rotor blocks uniformly distributed along the circumference direction out of the rotating shaft, Nr rotor blocks are fixedly connected with a circular non-magnetized rotor fixing device which is fixedly sleeved out of the rotating shaft and outwardly penetrates the C-shaped opening on the radial direction to enter the stator slot; axial air gaps are reserved between two end surfaces on axial direction of the rotor blocks and two end surfaces on the axial direction of the C-shaped openings; the inner diameter and outer diameter of each rotorblock are equal to the inner diameter and the outer diameter of the C-shaped opening; the radial force cannot produce between the stator and the rotor, the axial forces are mutually counteracted, andthe vibration noise of the motor in running is reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to an axial flux switch reluctance motor capable of reducing noise. Background technique [0002] The motor is a key part of an electric vehicle, and it should have the characteristics of safety, reliability, high efficiency, low speed, high torque, and low noise during operation. Due to its simple structure, flexible control, high efficiency, and strong fault tolerance, switched reluctance motors are gradually used in electric vehicles. The traditional switched reluctance motor has a large torque ripple during operation, and a large radial force is generated when the one-phase winding is excited and energized, which causes a large deformation of the motor casing, which in turn causes a large vibration noise. [0003] Chinese Patent Publication No. CN101557153A, titled "E-shaped Modular Stator Segmented Rotor Switched Reluctance Motor" discloses a switched reluctance motor composed ...
