The split-type stator is characterized in that the stator yoke portion is sectionalized; a groove is processed on one end of each section of the stator yoke portion, while a tenon is processed on the other end of each section of the stator yoke portion; the tenon of one section of the stator yoke portion fit with the groove of another section of the stator yoke portion; the enameled wires are wound on the sectionalized stator yoke portion and provided with the winding nozzles; the stator tooth portions are exposed out of the enameled wires; and in this way, a split stator core is formed and then the integral stator is prepared after the tenons and grooves of the stator yoke portions of all split stator cores are fitted together through tools.

Description

The split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor
Technical field
The utility model relates to the AC permanent-magnet Adjustable Speed Synchronous Motor, particularly relates to the split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, belongs to machine field.
Background technology
The AC permanent-magnet Adjustable Speed Synchronous Motor mainly is comprised of stator, rotor and transducer three parts, because rotor adopts the high-performance permanent magnet excitation, need not rotor excitation current, thereby there is no rotor copper loss; Be wound with simultaneously the threephase armature winding on the stator core of motor, be connected on controllable variable frequency power supply, the heating of motor concentrates on stationary part, and stator core directly contacts with extraneous by support, dispel the heat all right, can make motor be easy to realize miniaturization and lightweight.Installation of sensors is at the non-shaft stretching end of motor, and speed, position and position of magnetic pole that it can detect motor feed back to the motion that controller is controlled motor.Permagnetic synchronous motor also has the advantages such as efficient is high, power factor is high, control is relatively simple, so permagnetic synchronous motor obtains using more and more widely in fields such as various automation control appliances and electric automobiles.The rotor structure of permagnetic synchronous motor has two kinds, is divided into surface-mounted (SPM) and interpolation type (IPM), and 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 the 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, stator will adopt skewed slot, the winding coefficient k of motor usually w=k d* k p* k sk(k wWinding coefficient, k dBreadth coefficient, k pChording factor, k skSkew slot factor).Due to skew slot factor k skHeight, k sk<1, winding coefficient is reduced, for the utilance that improves the motor winding with improve the electromotive force waveform, can adopt fractional-slot to concentrate winding, namely every extremely every phase groove number is mark, winding is centralized winding.Owing to adopting centralized winding, machine automation easy to use is rolled off the production line, and has exempted that manual wire embedding's efficient is low, coil arrangement is irregular, the easy shortcoming such as injured of coil insulation.But in this structure, the minimum width of rebate bs0 of stator slot must be greater than the Breadth Maximum of coiling nozzle, thereby the cogging torque fluctuation of motor can not effectively be reduced (cogging torque by stator core and rotor field interact generation).Simultaneously in the coil winding process, for the coil that the nozzle damage of avoiding winding the line has wound, want sky to open a segment distance bs in iron core slot, cause copper factor low, motor resistance is large, moving consume high.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, it is the split manufacturing that a kind of stator core is provided, make the gap between each coil very little, the motor copper factor is high, the split type stator of the AC permanent-magnet Adjustable Speed Synchronous Motor that motor resistance is low, copper loss is economized.
the technical scheme of the split type stator of the utility model AC permanent-magnet Adjustable Speed Synchronous Motor is: comprise stator yoke section, enamelled wire, stator teeth and coiling nozzle, it is characterized in that described stator yoke section is the stator yoke section of segmentation, one in the stator yoke section of segmentation is shaped with groove, the other end of the stator yoke section of segmentation is shaped with tenon, tenon matches with the groove of another segmentation, described enamelled wire is to be wound in the stator yoke section of segmentation, enamelled wire has the coiling nozzle, stator teeth is exposed at outside enamelled wire, make the stator core of split, with the tenon of the stator yoke section in the stator core of each split with after the groove frock coordinates, make whole stator.
the utility model discloses a kind of split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, split type stator core construction after improvement, at first make the stator yoke section of segmented, groove processed of stator yoke section in segmentation, other end tenon processed, coiling enamelled wire in stator yoke section again, section is divided into one section one section due to stator yoke, so when the coiling enamelled wire, can not collide with adjacent enamelled wire, make the gap bs between two coils can accomplish close to zero, overcome the gap bs1 large shortcoming between two coils that prior art is coiled into due to one-piece stator yoke section, make the motor copper factor improve, reduce motor resistance, further reduced the motor copper loss, adopt again special frock, rely on stator groove and stator tenon interference fits, obtain piecing together whole stator.

Embodiment
the utility model relates to a kind of split type stator of AC permanent-magnet Adjustable Speed Synchronous Motor, as Fig. 1-shown in Figure 2, comprise stator yoke section, enamelled wire, stator teeth and coiling nozzle, it is characterized in that described stator yoke section is the stator yoke section 1 of segmentation, one in the stator yoke section 1 of segmentation is shaped with groove 11, the other end of the stator yoke section of segmentation is shaped with tenon 12, tenon 12 matches with the groove 11 of another sectionalized stator yoke section, described enamelled wire 2 is in the stator yoke section 1 that is wound on segmentation, enamelled wire 2 has coiling nozzle 3, stator teeth 4 is exposed at enamelled wire 2 outsides, make the stator core 5 of split, with the tenon 12 of the stator yoke section in the stator core of each split with after groove 11 frocks coordinate, make whole stator 6.split type stator core 5 structures after improvement, at first make the stator yoke section 1 of segmented, groove 11 processed of stator yoke section in segmentation, other end tenon 12 processed, coiling enamelled wire 2 in stator yoke section again, section is divided into one section one section due to stator yoke, so when the 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 gap bs1 large shortcoming (as shown in Figure 3) between two coils that prior art is coiled into due to one-piece stator yoke section, make the motor copper factor improve, reduce motor resistance, further reduced the motor copper loss, adopt again special frock, rely on stator groove 11 and stator tenon 12 interference fits, obtain piecing together whole stator 6.
