Embodiment 1

[0037] refer to figure 1 with figure 2 , the present embodiment provides a high-power automobile starter, comprising a rotor 1 and a stator housing 2, the inner wall of the stator housing 2 is distributed along its circumferential direction with permanent magnet magnets 3, and the permanent magnet magnets 3 are all It is Ru-Fe-B magnet, and the permanent magnet magnets 3 are evenly distributed along the circumferential direction of the inner ring of the stator housing 2, and each stator housing 2 is provided with 4 permanent magnet magnets 3, that is, four-stage magnetic cylinders, The permanent magnet magnetic steel 3 is fixed on the inner wall of the stator housing 2 through soft iron 5, and the magnetic poles of the motor are installed according to the circumferential order of N-S-N-S according to the polarity.

Embodiment 2

[0039] refer to figure 1 with image 3 , the present embodiment provides a high-power automobile starter, comprising a rotor 1 and a stator housing 2, the inner wall of the stator housing 2 is distributed along its circumferential direction with permanent magnet magnets 3, and the permanent magnet magnets 3 are all It is a hybrid magnet for both RuFeB magnets and ferrite magnets. The permanent magnet magnets 3 are evenly distributed along the circumferential direction of the inner ring of the stator housing 2. Among any two adjacent permanent magnet magnets 3, one of them is It is ferrite magnet, and the other is RuFeB magnet. There are four permanent magnet magnets 3 inside the stator housing 2, that is, four-stage magnet cylinders. The permanent magnet magnets 3 are fixed to the stator housing through soft iron 5. On the inner wall of the body 2, the magnetic poles of the motor are arranged in the circumferential order of N-S-N-S according to the polarity.

Embodiment 3

[0041] refer to figure 1 with Figure 4 , the present embodiment provides a high-power automobile starter, comprising a rotor 1 and a stator housing 2, the inner wall of the stator housing 2 is distributed along its circumferential direction with permanent magnet magnets 3, and the permanent magnet magnets 3 are Ferrite magnets, or hybrid magnets used both as RuFeB magnets and ferrite magnets, permanent magnet magnets 3 are evenly distributed along the circumferential direction of the inner ring of the stator housing 2, and each stator housing 2 There are four permanent magnet magnets 3 inside, that is, four-stage magnet cylinders. The permanent magnet magnets 3 are fixed on the inner wall of the stator housing 2 through the lateral fixing parts 6. Since the thickness of the permanent magnet magnets 3 is reduced, The stator housing can be downsized while adapting to existing rotors.

Abstract

The invention provides a high-power automobile starter and a stator magnetic steel fixing method. The starter comprises a rotor and a stator shell; permanent magnetic steels are uniformly distributed on the inner wall of the stator shell in the circumferential direction; and all the permanent magnetic steels in the stator shell are rubidium-iron-boron magnetic steels, ferrite magnetic steels or mixed magnetic steels of the rubidium-iron-boron magnetic steels and the ferrite magnetic steels. The high-power automobile starter and the stator magnetic steel fixing method disclosed by the invention solve the problems that: currently, only an electric excitation starter is adopted under the condition that the magnetic intensity requirement is high; but, the electric excitation starter is complex in production process, high in production cost, long in period, lag in technology and high in rejection rate; and furthermore, the electric excitation starter is not beneficial to health of workers and environmental protection. The high-power automobile starter and the stator magnetic steel fixing method disclosed by the invention belong to the field of starters.

Description

technical field [0001] The invention relates to a starter and belongs to the field of vehicle engineering. Background technique [0002] The automobile starter is an indispensable and important part of the automobile. There are many types of automobile starters. The main difference is that the stator / magnetic steel of the starter is different, which leads to the difference in the performance of the starter. At present, the biggest weakness of the automobile starter is The magnetic strength is insufficient, and the driving force provided during starting is limited, which cannot meet the requirements of fast starting of the car. [0003] At present, the high-power starters for vehicles at home and abroad, the power is from 2.0kw-15kw or more, the magnetic field formed by the stator is energized by 4 windings made of flat copper wires to generate 4 magnetic poles to form a 4-pole magnetic field , is called an electric excitation starter, and because the mechanical transmission...
