Abstract
The utility model discloses an alternating current generator combined claw pole and a rotor, and relates to the automobile alternating current generator technology field. The alternating current generator combined claw pole 2 mainly includes second magnet yokes 21, a second shaft hole 22 and second pole claws 23. The alternating current generator rotor mainly includes two claw poles 1, combined claw poles 2, a rotary shaft 4, two magnetic field windings 3, and a collecting ring. The beneficial effects are that through changing the structures of the claw pole and the rotor, the stator coil utilization rate is improved, and the increased proportion of the alternating current generator power output is bigger than the increased proportion of material consumption.
Description
Technical field
The utility model relates to a kind of alternating current generator technical field, relates in particular to a kind of pawl utmost point and rotor for AC generator for vehicle.

In automobile, the effect of alternating current generator is that the part mechanical energy with engine becomes electric energy, the power consumption equipment of automobile is powered, and in time storage battery is carried out boost charge.Alternating current generator mainly is comprised of rotor, stator and front and rear cover etc.Rotor is the rotating magnetic field part of three-phase synchronous alternator, belongs to critical component.
As shown in FIG., Fig. 1 is a kind of comparatively typical alternating current generator pawl utmost point in prior art, and this pawl utmost point comprises utmost point pawl 13, yoke 11, axis hole 12; Fig. 2 is a kind of comparatively typical alternator rotor in prior art, and this rotor comprises the pawl utmost point 1, magnetic field winding 3, rotating shaft 4 and collector ring (not marking in figure).Yoke 11 covers of two pawl utmost points 1 have magnetic field winding 3, and utmost point pawl 13 dislocation intersections relatively are fitted in rotating shaft 4.The lead-in wire of magnetic field winding 3 is welded in respectively on two collector rings (not marking in figure).When generator was worked, two collector rings were communicated with DC power supply, for magnetic field winding 3 provides directional current and produces axial magnetic flux, made the utmost point pawl 13 of two pawl utmost points 1 produce along the circumferential direction alternate the N utmost point and the S utmost point.The N utmost point and the S utmost point consist of the closed-loop path by the tooth of stator core, when rotor rotates, make the stator coil cutting magnetic line in stator core slot, and at this moment stator coil is outwards exported with regard to generation current, so-called generating that Here it is.Stator coil is continuous coiling, its straight line portion is in the groove of stator core, the end winding of coupling part is in the stator core outside, the stator coil of stator core exterior portion does not participate in cutting magnetic line, just there is no generation current yet, that is to say the live part of stator coil in the groove of stator core, but the stator core of present most alternating current generators is axially shorter, makes the stator coil utilance not high.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of alternator combination pawl utmost point and rotor.
In order to overcome the defective that exists in prior art and to realize above-mentioned utility model purpose, the utility model discloses a kind of for the alternator combination pawl utmost point, comprise: the second yoke, the second axis hole and the second utmost point pawl, it is characterized in that, the second utmost point pawl and the second yoke with the second axis hole perpendicular plane on become symmetrical enantiotropy to distribute.Further, this second utmost point pawl and the second yoke are made by permeability magnetic material, and this second utmost point pawl and the second yoke are made one.。
[0006] the utility model discloses a kind ofly for alternator rotor simultaneously, comprising: the pawl utmost point, the combination pawl utmost point, rotating shaft, magnetic field winding and collector ring, it is characterized in that, and this rotor comprises two pawl utmost points, two field coils, the combination pawl utmost point and rotating shafts.Further, the combination pawl utmost point is placed in the centre of two pawl utmost points, and the first utmost point pawl is with second utmost point pawl is relative intersects, the first yoke contacts with the end face of the second yoke, field coil is enclosed within the outer round surface of the first yoke and the second yoke, and the axis hole that the pawl utmost point and the combination pawl utmost point are passed in rotating shaft fixedly becomes rotor integral body.
Compared with prior art, the utility model improves the utilance of stator coil by changing the structure of the pawl utmost point and rotor, makes the raising ratio of alternator output output greater than the growth ratio of material consumption.
