Abstract
The utility model discloses a kind of pole jaw of car electricity generator structure, it includes chassis, the outer rim on the chassis is extended with several magnetic poles to homonymy, and several described magnetic poles are equally spaced, and the lateral surface of several magnetic poles is arc surface and is on same circumference, mounting hole is offered at the center on the chassis, wherein, the structure of several magnetic poles is identical, and the bottom of its medial surface is arc surface, top is inclined-plane, and the thickness of the arc surface is more than the thickness on the inclined-plane.Above-mentioned pole jaw of car electricity generator structure optimizes to the shape of magnetic pole, is arc surface by the medial surface bottom design of magnetic pole.It is not only simple in structure, it is easy to accomplish；And reduce leakage field, substantially increase the low-speed performance of generator.
Description
Technical field
Automobile current generator is the utility model is related to, more particularly, to a kind of pole jaw of car electricity generator structure.
Background technology
Generator is the main power source of automobile electrical equipment, in automobile during normal operation, generator to except starter it
Other outer power supply for electrical equipment.Claw pole electric generator has the characteristics of being simple to manufacture, cost is cheap, is mainly used in small-sized generating
Occasion, especially as automobile current generator.
At present, pole pawl is the important component of Lundell automobile current generator, and its quality designed directly influences automobile generating
The overall performance of machine.The pawl pole of existing automobile current generator generally comprises chassis and several magnetic poles being arranged on chassis, institute
The lateral surface for stating magnetic pole is arc surface, and its medial surface is an inclined-plane.The magnetic pole of this structure during concrete application, magnetic leakage compared with
Greatly, especially in generator tick-over, the low-speed performance of generator is influenceed.
Utility model content
The purpose of this utility model is to provide a kind of pole jaw of car electricity generator structure, and it can reduce leakage field, improve
The low-speed performance of generator, to solve above mentioned problem existing for pole jaw of car electricity generator in the prior art.
To use following technical scheme up to this purpose, the utility model：
A kind of pole jaw of car electricity generator structure, it includes chassis, and the outer rim on the chassis is extended with several magnetic to homonymy
Pole, several described magnetic poles are equally spaced, and the lateral surface of several magnetic poles is arc surface and is on same circumference,
Wherein, the structure of several magnetic poles is identical, and the bottom of its medial surface is arc surface, and top is inclined-plane, the arc surface
Thickness is more than the thickness on the inclined-plane.
Especially, the magnetic pole generally pyramidal structure, its outer end width are less than the width of the other end.
Especially, mounting hole is offered at the center on the chassis.
Especially, chamfering is offered on the another side on the chassis relative to setting magnetic pole.
Especially, the angle of inclination on the inclined-plane is 25 °~30 °.
The beneficial effects of the utility model are, compared with prior art shape of the pole jaw of car electricity generator structure to magnetic pole
Shape optimizes, and is arc surface by the medial surface bottom design of magnetic pole.It is not only simple in structure, it is easy to accomplish；And reduce leakage
Magnetic, substantially increase the low-speed performance of generator.
