Abstract
The utility model discloses a permanent magnet synchronous motor. The permanent magnet synchronous motor comprises a stator, a rotor, a housing and a motor shaft. The stator fixed in the housing is provided with a winding; the motor shaft provided with the rotor is connected with the housing through two bearings; the rotor is provided with a permanent magnet; and one end of the motor shaft extends out of the housing as the output shaft end of a motor, and the other end of the motor shaft is provided with a heat dissipation fan. The synchronous motor provided by the utility model has the following advantages: the structure is simple, the only wearable part is a bearing, the service life is long, and the noise is low. During the rotation progress of the synchronous motor, the heat dissipation fan is simultaneously driven to rotate so as to dissipate heat inside the synchronous motor.
Description
Technical field
The utility model relates to a kind of motor, more precisely, relates to a kind of permagnetic synchronous motor.
Background technology
DC motor speed-regulating performance of the prior art is better than, and low-speed performance is good, operates steadily, but due to the existence of mechanical switching device, and brush need to often safeguard, and operation can produce commutation spark, causes radio interference.In existing brushless electric machine, its complex structure, and also noise is larger.
The heat dissipation problem of motor is perplexing people always, and the heat radiation of motor in prior art, generally all adopts radiating ribs is set on casing, increases the area of dissipation of motor, but the efficiency of this radiator structure is extremely low.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of permagnetic synchronous motor.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of permagnetic synchronous motor, comprise stator, rotor, housing, motor shaft, the stator being fixed in housing is provided with winding, the motor shaft that rotor is installed is connected with housing by two bearings, described rotor is provided with permanent magnet, and housing is stretched out as the output shaft end of motor in one end of motor shaft, and the other end is provided with radiator fan.
Synchronous machine of the present utility model, it is simple in structure, and the place of unique wearing and tearing is exactly bearing, long service life, and also noise is low.In the rotation process of synchronous machine, drive radiator fan to rotate simultaneously, thereby the dissipation of heat of synchronous machine inside is gone out
Accompanying drawing explanation
Fig. 1 shows the structural representation of the utility model synchronous machine.
Embodiment
For the technical problem that the utility model is solved, the technical scheme of employing, the technique effect easy to understand of obtaining, below in conjunction with concrete accompanying drawing, embodiment of the present utility model is described further.
With reference to figure 1, a kind of permagnetic synchronous motor that the utility model provides, comprises stator 3, rotor 4, housing 1, motor shaft 5, stator 3 is fixedly mounted in housing 1, on described stator 3, be tied with winding 31, rotor 4 is fixed on motor shaft 5, so that rotor drive motors axle 5 rotates.Motor shaft 5 is connected with housing 1 by two bearings 2, and described rotor 4 is provided with permanent magnet 41, and this permanent magnet 41 can adopt the rare earth material that temperature stability is high to make, the features such as magnetic energy product is high, stable performance that it has.Permanent magnet 41 and rotor 4 have formed permanent magnetism rotor, are combined together with the stator that is tied with winding 31.Housing 1 is stretched out as the output shaft end of motor in one end of motor shaft 5, and the other end is provided with radiator fan 6.
Synchronous machine of the present utility model, it is simple in structure, and the place of unique wearing and tearing is exactly bearing, long service life, and also noise is low.In the rotation process of synchronous machine, drive radiator fan to rotate simultaneously, thereby the dissipation of heat of synchronous machine inside is gone out.
The utility model is by preferred embodiment having carried out detailed explanation.Yet, by studying carefully above, to the variation of each execution mode with to increase be also that one of ordinary skill in the art institute is apparent.Being intended that all these variations and increasing of applicant all dropped in the scope that the utility model claim protects.
Similar numbering refers to similar element in the whole text.For clarity, may there is in the accompanying drawings the situation that some line, layer, element, parts or feature are amplified.
Term used herein is only for to be illustrated specific embodiment, and it is not intended to the utility model to limit.Unless otherwise defined, all terms used herein (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.
