Abstract
A rotator with permanent magnets comprises a shaft. A front claw pole, an excitation coil, a back claw pole and a collecting ring are sleeved sequentially on the shaft, claw-shaped magnetic poles of the front claw pole and the back claw pole are in staggered arrangement to form a containing chamber, and permanent magnets are arranged between each two adjacent claw-shaped magnetic poles. The rotator with the permanent magnets is characterized in that a limiter is arranged on a concave portion of the same claw pole and used for sealing the claw pole. The limiters are arranged to clamp the permanent magnets, so that the shape of a cross section of the containing chamber does not need to strictly conform to cross sections of the permanent magnets, and processing difficulty is lowered, processing cost is low, mounting is simple and convenient and consumed time is short; and when assembly of the rotator is completed, a front fan and a back fan are mounted on the front claw pole and the back claw pole respectively, the limiters are positioned on the concave portions of the claw poles, and the front and back fans provide clamping force for the limiters, so that firm clamping is realized, and damages to the motor caused by the detached permanent magnets when the rotator rotates at a high speed are avoided.
Description
Technical field
The present invention relates to the band PM rotor in the alternator for vehicle.
Background technology
Rotor is to be used to realize the part of mechanical energy to the electric energy conversion in the motor; In CN102315711 A, disclose a kind of first current generator rotor, this rotor is made up of axle, permanent magnet and the forefan, the fore paw utmost point, magnetizing coil, the rear solid end utmost point, aft-fan, the collector ring that are sleeved on successively on the axle.The claw-like magnetic pole of the described front and back pawl utmost point is staggered arranges, and is provided with container cavity between two adjacent claw-like magnetic poles, and described permanent magnet is positioned at container cavity.The shape strict conformance of the shape of container cavity cross section and permanent magnet cross section, its requirement on machining accuracy is high, so the container cavity processing difficulties, and processing cost is high, and difficult installation, length consuming time; In addition; Container cavity only relies on location block body restriction permanent magnet moving on rotor radial; And rotor often is in rapidly and rotates, increases and decreases fast state and hot environment, and deformation or wearing and tearing very easily take place the location block body, in case the location block body can't provide spacing for permanent magnet; Permanent magnet is thrown out of, and will cause motor to be smashed.
Summary of the invention
The technical problem that the present invention will solve provides a kind of handling ease, processing cost is low, installation is convenient, weak point consuming time, the firm band PM rotor of clamping.
The present invention is achieved in that
A kind of band PM rotor; Comprise axle; On axle, be set with the fore paw utmost point, magnetizing coil, the rear solid end utmost point, collector ring successively, the staggered formation container cavity of arranging of the claw-like magnetic pole of the described fore paw utmost point and the rear solid end utmost point is provided with permanent magnet between two adjacent claw-like magnetic poles; Its special character is: the indentation at the same pawl utmost point is provided with limit body, through limit body with pawl utmost point involution.
The said pawl utmost point and limit body are one.
The material of said guide vane end stop is a non-magnet material, to reduce the leakage field of pawl interpolar.
Between said limit body and the claw-like for divide body structure and therebetween convex-concave cooperates, with the minimizing leakage field.
The outer of said limit body is provided with blend stop, makes permanent magnet more firm.
Said limit body inner surface is respectively equipped with a through hole and a blind hole, is positioned at respectively corresponding two the adjacent container cavities of through hole and blind hole on the same limit body, and the shape of described through hole and blind hole and the shape of permanent magnet cross section are consistent, to hold permanent magnet.
Same container cavity two ends are corresponding through hole and blind hole respectively, the through hole on the extremely corresponding limit body of fore paw, blind hole arrange with the extremely corresponding limit body of rear solid end on the distributing order of through hole, blind hole opposite.
Said through hole and blind hole tilt at the periphery that the claw-like magnetic pole changes into, and incline direction is with consistent with the incline direction of its corresponding container cavity.
Be provided with guide vane end stop in the described through hole.
Described permanent magnet and limit body glued joint.
The invention has the beneficial effects as follows:
Owing to be provided with limit body clamping permanent magnet, the shape of container cavity cross section need not the shape strict conformance with the permanent magnet cross section, has reduced that difficulty of processing, processing cost are low, simple installation, weak point consuming time; After rotor assembling is accomplished, forward and backward fan is installed at forward and backward pawl on extremely, because limit body is positioned at the indentation of the pawl utmost point, forward and backward fan is that limit body provides clamping force, and clamping is firm, has avoided being smashed motor because of permanent magnet gets rid of to take off when rotor high-speed rotates.
