Abstract
The utility model discloses an automobile generator claw pole comprising six magnetic poles, magnetic yokes, a shaft hole, and lead wire grooves. The six magnetic poles are equally arranged, and the magnetic yokes are disposed on inner sides of the magnetic poles. The shaft hole is disposed in a central position of the claw pole, and the lead wire grooves are disposed in a radial plane of an outer side of the claw pole. The automobile generator claw pole is advantageous in that after the improvement of the automobile motor rotor, the magnetic flux of each of the magnetic poles can be increased, the magnetic flux distribution can be improved, and the performance of the generator can be improved.
Description
Technical field
The utility model relates to a kind of pawl utmost point, particularly relates to a kind of automobile generator claw pole.
Background technology
Automobile current generator is to provide a kind of equipment of car electrics electric energy, how to improve the electricity generation efficiency of generator, is the important content that people are concerned about.The pawl of automobile current generator is extremely generally made pointed, mainly exists magnetic pole strength little, and the magnetic flux under pole-face is little, affects the induced electromotive force of generator.Simultaneously, because the magnetic pole neutral line and stator coring groove have angle, cause the phase place of the electromotive force that the different parts of the stator winding conductor of same groove responds to inconsistent, total electromotive force is made a discount, the generator fan-out capability is descended, cause especially the automobile storage battery undercharge when low speed.In order to improve the automobile current generator power generation performance, the power generator rotor magnetic pole shape is improved, increase every utmost point magnetic flux, improve magnetic flux distribution, improve generator performance.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of automobile generator claw pole, and it can improve magnetic flux distribution, improves generator performance.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of automobile generator claw pole, and it comprises magnetic pole, yoke, axis hole, wire lead slot, the quantity of magnetic pole is six equal distribution; Yoke is positioned at the inboard of magnetic pole; Axis hole is positioned at the center of the pawl utmost point; Wire lead slot is arranged on pawl utmost point outer radial plane.
Preferably, the pole-face of described magnetic pole be shaped as square.
Preferably, the side of described magnetic pole is trapezoidal.
Preferably, the width of described magnetic pole is 20mm to 24mm.
Positive progressive effect of the present utility model is: the utility model automobile generator claw pole, by the shape by the magnetic pole pole-face, by sharp mouth shape, be improved to square, thereby strengthened magnetic pole strength, the magnetic flux under each pole-face is increased, improved the induced electromotive force of generator.Simultaneously, make the magnetic pole neutral line parallel with stator coring groove, can make the phase place of the electromotive force that the different parts of the stator winding conductor of same groove responds to consistent, total electromotive force is strengthened, improved the generator fan-out capability, increase every utmost point magnetic flux, improve magnetic flux distribution, improve generator performance.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model automobile generator claw pole.
The right view that Fig. 2 is the utility model automobile generator claw pole.
Fig. 3 is the Distribution of Magnetic Field schematic diagram before the utility model automobile generator claw pole magnetic pole pole-face improves.
Fig. 4 is the Distribution of Magnetic Field schematic diagram after the utility model automobile generator claw pole magnetic pole pole-face improves.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figures 1 to 4, the utility model automobile generator claw pole comprises magnetic pole 1, yoke 2, axis hole 3, wire lead slot 4, and the quantity of magnetic pole 1 is six equal distribution; Yoke 2 is positioned at the inboard of magnetic pole 1; Axis hole is positioned at the center of the pawl utmost point; Wire lead slot is arranged on pawl utmost point outer radial plane.Being shaped as of the pole-face of magnetic pole 1 is square, and the side of magnetic pole is trapezoidal; Being shaped as of yoke 2 is cylindrical; Wire lead slot 4 be shaped as semicircle orifice; The utility model automobile generator claw pole, by the improvement to the generator claw pole pole form, increases every utmost point magnetic flux, improves magnetic flux distribution (as shown in Figure 3 and Figure 4, A represents pole span), improves generator performance.The width of magnetic pole is 20mm to 24mm.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
