Description
Technical field
The utility model relates to permagnetic synchronous motor, relates to a kind of permanent-magnetic synchronous motor stator structure or rather.
Background technology
At present, induction machine adopts winding generation rotating magnetic field to pull rotor to rotate usually, for ensureing the steady output of power of motor, the magnetic field that winding produces should be uniformly distributed in stator interior in the cycle, but due to coil winding mode, for being wound around the distribution around tooth of copper cash, the shape of stator yoke etc., all can affect the cycle of magnetic field in stator and be uniformly distributed, cause circle distribution direction, magnetic field area not, Magnetic field inhomogeneity, thus the noise of motor, vibration, torque pulsation are increased, efficiency reduces.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of Distribution of Magnetic Field uniform permanent-magnetic synchronous motor stator structure.
Technical solution of the present utility model is, a kind of permanent-magnetic synchronous motor stator structure with following structure is provided, comprise and being overrided to form from top to down by some punching bodies, each punching body comprises yoke portion, teeth portion and centre bore, described teeth portion comprise the arrangement of some centrally holes uniform circular around tooth, adjacently between tooth, form teeth groove, described adjacent between tooth width centreline angle be 20 degree to 27 degree, described yoke portion sidewall is circumferentially provided with some welding grooves, and one of them described welding groove one sidewall is provided with mark groove.
After adopting above structure, permanent-magnetic synchronous motor stator structure of the present utility model, compared with prior art, have the following advantages: by by described teeth portion centrally hole uniform circular arrangement, and described adjacent between tooth axis angle be 20 degree to 27 degree, ensure that magnetic field was uniformly distributed in the stator interior cycle, and some welding grooves are evenly set by side, yoke portion, make welding groove minimum to stator interior influence of magnetic field, and mark groove is arranged on welding groove sidewall, decrease the impact of mark groove on stator structure, make stator interior magnetic field more even, thus improve the operational efficiency of motor.
Because described yoke portion of the present utility model is provided with some axially extending bores, described axially extending bore arrange with around tooth and junction, yoke portion, the radiating effect that some axially extending bores strengthen stator structure is set, and described axially extending bore arrange with around tooth and junction, yoke portion, make stator structure more even, make stator interior Distribution of Magnetic Field more even.
Improve as one of the present utility model, described welding groove bottom surface is waveform, welding groove bottom shape is arranged to waveform and not only ensure that welding effect, and decrease the width of welding groove, greatly reduce the impact of welding groove on stator interior magnetic field, make stator interior Distribution of Magnetic Field more even.
Improve as another kind of the present utility model, between the axis of described adjacent fingers, angle is 20 degree, makes stator structure more balanced, magnetic field was uniformly distributed in the stator interior cycle, ensure that magnetic field utilance, makes motor operational efficiency higher.
