Brief description of the drawings
Fig. 1 is the rotor structure schematic diagram of synchronous magnetic resistance motor one embodiment of the present utility model;
Fig. 2 is that the rotor of synchronous magnetic resistance motor one embodiment of the present utility model coordinates schematic diagram with stator.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, synchronous magnetic resistance motor of the present utility model is further elaborated.Should be appreciated that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
See figures.1.and.2, synchronous magnetic resistance motor one embodiment of the present utility model is 6-pole motor, comprise rotor and the stator with winding, at rotor in the radial direction, on each magnetic pole of rotor, be provided with multilayer arc magnet steel groove, in magnet steel groove, be provided with magnet steel, wherein between adjacent two-layer magnet steel groove, form a q axle magnetic circuit (rib), the electrical degree in the two-port center of described q axle magnetic circuit (rib) and the center of circle of rotor is θ (mechanical angle * number of pole-pairs), wherein, 90 °≤θ≤124 °, multiple magnetic poles are set on rotor, magnet steel groove distributes at described rotor radial even circumferential.Magnet steel groove on each magnetic pole of figure rotor is two-layer arc magnet steel groove, be respectively the first magnet steel groove 2 and the second magnet steel groove 3, in the first magnet steel groove 2, insert in the first magnet steel 4. second magnet steel grooves 3 and insert the second magnet steel 5, the first magnet steel 4 and the second magnet steel 5 are ferrite lattice cheaply, ferrite lattice is mounted to the polarity N that makes them, the arrangement that S replaces in the side towards stator, so form multiple tracks flux-obstruction, between the first magnet steel groove 2 and the second magnet steel groove 3, form a q axle magnetic circuit (rib), on rotor core 1, also have central shaft hole 7 and rivet hole 6 simultaneously, the quantity of rivet hole 6 equals the number of magnetic poles of rotor, rivet hole 6 is uniformly distributed at the radial circumference of described rotor.
The inner periphery of stator 8 is evenly equipped with multiple teeth groove, and winding coil is set in teeth groove, and the width of rebate of teeth groove is L, and described magnetic circuit (rib) is k at the width of described rotor outermost circle one end, wherein, and 1.4L≤k≤2.5L.Preferably, angle place, described magnet steel groove two ends is horn structure, fillet structure or top rake (chamfering) structure.
So design, can make stator tooth corresponding to magnetic circuit (rib) between two-layer magnet steel groove is non-integer, thereby the q axle magnetic line of force is disperseed relatively, reduces torque ripple; On the other hand, between two-layer magnet steel groove, magnetic circuit (rib) is greater than stator rabbet width at rotor outermost circle one end width, and in the time that between two-layer magnet steel groove, magnetic circuit (rib) one end forwards stator slot position to, its magnetic line of force can be come in and gone out from the tooth on stator slot both sides, further disperse the magnetic line of force, reduce torque ripple; On the one hand, the shared rotor circumference of magnet steel groove mechanical angle is radially less again, and the distance of the each interpolar of rotor (die opening) is larger, and the magnetic line of force can be come in and gone out from multiple stator tooths, and the rotor circumference magnetic line of force is evenly distributed rationally, reduces rotor and tangentially pulses; Moreover q magnetic circuit width increases, saturated reducing, more by the magnetic line of force, therefore motor is exerted oneself and can obviously do not declined, and efficiency is high.
In a word, above-mentioned design can make each magnetic circuit width and stator tooth width in most suitable scope (with stator teeth groove corresponding relation), exert oneself constant in the situation that at motor, the magnetic line of force distributes rationally, to reduce torque pulsation (torque ripple particularly being caused by slot effect) and radial cut to electromagnetic force, thereby reduce vibration and the noise in running.
The synchronous magnetic resistance motor of above embodiment, exerts oneself large, and efficiency is high, and electromagnetic noise is low, and its torque ripple declines 50% than similar conventional motor, and the torque ripple corresponding with stator teeth groove and tangential force decline.Be applied to compressor of air conditioner, can effectively reduce motor torque fluctuation and electromagnetic force, reduce motor and vibration of compressor noise.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
