Abstract
The utility model discloses an automobile engine claw pole rotor with permanent magnet for automobile motors. The automobile engine claw pole rotor comprises front claw poles, back claw poles, a shaft, an excitation coil, a bearing and a slip ring, wherein a groove is processed on a lateral face between the N pole of each front claw pole and the S pole of the back claw pole, a permanent magnet is installed in the groove, the two lateral faces the permanent magnet are respectively an N pole and an S pole, which are consistent with the N pole and the S pole of the front claw pole and the back claw pole, and enhances the excitation magnetic fields of the front claw pole and the back claw pole, thereby an engine adopting the claw pole rotor can improve the low-speed performance, and outputs large current under lower rotation speed. The automobile engine claw pole rotor solves the weaknesses that when an automobile operates at low speed, an automotive engine can not meet the demands and is supplied with electric power by a storage battery, and plays the effects of protecting the storage battery of the automobile and improving the reliability of the automobile.
Description
Technical field
The utility model relates to the electric motor of automobile field, is specifically related to a kind of claw pole for automobile generator rotor.
Background technology
Along with popularizing that automobile uses, people are more and more higher to the requirement of automobile, require automobile safety and reliability height, and failure rate is low; Do not have permanent magnetic iron in the automobile generator claw pole rotor in the market; but with mild steel or mild steel material; utilize the remanent magnetism sectioned coil of this material and produce electric current; since remanent magnetism a little less than; (more than 1300 rev/mins) can not reach rated current when rotor reaches certain rotating speed; therefore generator can not reach rated current during engine idle; can only lean on the storage battery power supply this moment; the idling of long period can exhaust the electric current of storage battery; so that engine cisco unity malfunction; how to overcome this drawback, protection automobile storage battery and raising automobile reliability are the directions that the sector technical staff makes great efforts.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art; reach and improve the automobile current generator low-speed performance; the utility model provides a kind of band permanent magnetic iron formula automobile generator claw pole rotor that is used for electric motor of automobile; make automobile under different rotating speeds, can export big electric current; automobile current generator can not be satisfied the demand during with solution automobile low cruise; and to lean on the drawback of storage battery power supply, played the effect that the protection automobile storage battery improves the automobile reliability.
The technical scheme that realizes above-mentioned purpose is: a kind of claw pole for automobile generator rotor comprises the fore paw utmost point, the rear solid end utmost point, axle, magnetizing coil, bearing, slip ring, lining ring, magnet steel, back fan blade, antifreeze plate; The described fore paw utmost point and the rear solid end utmost point, both N, the S utmost point, by mutual canine tooth across, and fixed on the middle part that is sleeved on axle of gap equalization and by lining ring, between each fore paw utmost point N utmost point and the rear solid end utmost point S utmost point, be processed with groove on the relative side, the two sides that permanent magnetic iron, permanent magnetic iron are installed in this groove are respectively N, the S utmost point, and are extremely consistent with N, the S of the forward and backward pawl utmost point respectively, strengthen the magnetic field intensity of main field between the fore paw utmost point and the rear solid end utmost point with this.
Above-mentioned a kind of claw pole for automobile generator rotor, described antifreeze plate is placed between permanent magnetic iron and the described groove, and with adhesive permanent magnetic iron is fixed in the described groove.
The utility model is owing to increased permanent magnetic iron between each the fore paw utmost point N utmost point of pawl utmost point rotor and the rear solid end utmost point S utmost point, make the excitation field that produces between the fore paw utmost point N utmost point and the rear solid end utmost point S utmost point strengthen to some extent, and then make the low-speed performance of generator be much improved, can be at the electric current big than output under the slow-speed of revolution.Adopted the automobile current generator behind the utility model; output current when 1100 rotating speeds has reached the output current when orthodox car generator 1300 rotating speeds are above; so also can solve automobile automobile current generator when long-time low cruise can not satisfy the demand; and to lean on the drawback of storage battery power supply, the effect of having played the protection automobile storage battery and having improved the automobile reliability.
Description of drawings
Fig. 1 is the schematic diagram of band permanent magnetic iron formula automobile generator claw pole rotor;
Fig. 2 is the p-p profile of Fig. 1.
Embodiment,
See also Fig. 1, in order to understand the technical solution of the utility model better, below by embodiment particularly and in conjunction with the accompanying drawings 1 and Fig. 2 be described in detail.
A kind of electric motor of automobile of the present utility model comprises axle 1, lining ring 2, the fore paw utmost point 3, magnetizing coil 4, the rear solid end utmost point 5, back fan blade 6, bearing 7, slip ring 8, permanent magnetic iron 9, antifreeze plate 10 with band permanent magnetic iron formula automobile generator claw pole rotor; The fore paw utmost point 3 and the rear solid end utmost point 5 (being the N and the S utmost point) are by mutual canine tooth across, and fixed on the middle part that is sleeved on axle of pawl clearance between poles equalization and by lining ring 2, between each fore paw utmost point N utmost point and the rear solid end utmost point S utmost point, be processed with groove on the relative pawl utmost point side, permanent magnetic iron 9 is installed in the groove, the two sides of permanent magnetic iron 9 are respectively N, the S utmost point, extremely consistent with N, the S of the forward and backward pawl utmost point, strengthen the intensity of main field between the fore paw utmost point 3 and the rear solid end utmost point 5 with this.
Be placed with antifreeze plate 10 between permanent magnetic iron 9 and the groove, and permanent magnetic iron 9 be fixed in the machined grooves on the two pawl utmost point sides with adhesive.
The utility model is owing to increased permanent magnetic iron between the S utmost point of the N utmost point of each fore paw utmost point 3 of pawl utmost point rotor and the rear solid end utmost point 5, make the excitation field that between the S utmost point of the N utmost point of the fore paw utmost point 3 and the rear solid end utmost point 5, produces strengthen to some extent, and then make the low-speed performance of generator be much improved, can under different rotating speeds, export big electric current.Automobile current generator can not be satisfied the demand in the time of so also can having solved the automobile low cruise, and will lean on the drawback of storage battery power supply, has played the effect that the protection automobile storage battery improves the automobile reliability.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
