Description
Technical field
The present invention relates to AC permanent-magnet Adjustable Speed Synchronous Motor, particularly relate to the split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, belong to machine field.
Background technology
AC permanent-magnet Adjustable Speed Synchronous Motor, primarily of stator, rotor and transducer three part composition, because rotor adopts high-performance permanent magnet excitation, without the need to rotor excitation current, does not thus have rotor copper loss; On the stator core of motor, be wound with threephase armature winding simultaneously, be connected in controllable variable frequency power supply, the heating of motor concentrates on stationary part, and stator core is direct and extraneous contact by support, heat dispersal situations is good, and motor can be made to be easy to realize miniaturized and lightweight.Transducer is arranged on the non-shaft stretching end of motor, and it can detect the speed of motor, position and position of magnetic pole and feed back to the motion that controller controls motor.Permagnetic synchronous motor also has the advantages such as efficiency is high, power factor is high, control is relatively simple, so permagnetic synchronous motor obtains applying more and more widely in fields such as various automation control appliance and electric automobiles.The rotor structure of permagnetic synchronous motor has two kinds, and be divided into surface-mounted (SPM) and interpolation type (IPM), SPM rotor structure leakage field is little, and magnetic flux density is high, and the magnet steel design of special shape can produce sinusoidal wave magnetic flux, and the design is mainly for SPM rotor structure.When the stator design of permagnetic synchronous motor, in order to reduce the high order harmonic component of winding electric kinetic potential, prior art generally adopts distributed winding, and winding overhang is longer; In order to weaken slot ripples, usual stator will adopt skewed slot, the winding coefficient k of motor

Summary of the invention
The object of the invention is the shortcoming existed to overcome prior art, a kind of stator core is provided to be split manufacture, make the gap between each coil very little, motor copper factor is high, the split type stator of the AC permanent-magnet Adjustable Speed Synchronous Motor that electric motor resistance is low, copper loss is economized.
The technical scheme of the split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor of the present invention is: comprise stator yoke, enamelled wire, stator teeth and coiling nozzle, it is characterized in that described stator yoke is the stator yoke of segmentation, groove is shaped with of stator yoke of segmentation, the other end of the stator yoke of segmentation is shaped with tenon, the fit depressions of tenon and another segmentation, described enamelled wire is be wound in the stator yoke of segmentation, enamelled wire has coiling nozzle, stator teeth is exposed at outside enamelled wire, the stator core of obtained split, after the tenon of the stator yoke in the stator core of each split is coordinated with groove frock, make overall stator.
The invention discloses a kind of split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, split type stator core construction after improvement, first the stator yoke of segmented is made, at stator yoke groove processed of segmentation, other end tenon, coiling enamelled wire in stator yoke again, because stator yoke is divided into one section one section, so when coiling enamelled wire, can not collide with adjacent enamelled wire, gap bs between two coils can be accomplished close to zero, overcome the shortcoming that gap bs1 between two coils that prior art is coiled into due to one-piece stator yoke portion is large, motor copper factor is improved, reduce electric motor resistance, further reduce copper wastage, adopt special frock again, rely on stator groove and stator tenon interference fits, obtain piecing together overall stator.

Embodiment
The present invention relates to a kind of split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, as shown in Fig. 1-Fig. 2, comprise stator yoke, enamelled wire, stator teeth and coiling nozzle, it is characterized in that described stator yoke is the stator yoke 1 of segmentation, groove 11 is shaped with of stator yoke 1 of segmentation, the other end of the stator yoke of segmentation is shaped with tenon 12, tenon 12 matches with the groove 11 in another sectionalized stator yoke portion, described enamelled wire 2 is for being wound in the stator yoke 1 of segmentation, enamelled wire 2 has coiling nozzle 3, stator teeth 4 is exposed at outside enamelled wire 2, the stator core 5 of obtained split, after the tenon 12 of the stator yoke in the stator core of each split is coordinated with groove 11 frock, make overall stator 6.Split type stator core 5 structure after improvement, first the stator yoke 1 of segmented is made, at stator yoke one groove 11 processed of segmentation, other end tenon 12, coiling enamelled wire 2 in stator yoke again, because stator yoke is divided into one section one section, so when coiling enamelled wire, can not collide with adjacent enamelled wire, make the gap bs between two coils can accomplish close to zero (as shown in Figure 1), overcome the shortcoming (as shown in Figure 3) that gap bs1 between two coils that prior art is coiled into due to one-piece stator yoke portion is large, motor copper factor is improved, reduce electric motor resistance, further reduce copper wastage, adopt special frock again, rely on stator groove 11 and stator tenon 12 interference fits, obtain piecing together overall stator 6.
