Description

Pole piece spacing coiling combined-stator

Technical field

The present invention is a kind of pole piece spacing coiling combined-stator, is related to a kind of motor stator, more particularly to one Centralized winding coil is wound successively on the core magnetic pole pole body of two stator cores and magnetic pole insert kind respectively, and makes two The magnetic pole insert of stator core is interleaved alternately with the motor stator of tongue-and-groove between the two neighboring core magnetic pole pole body of opposite stator core Son.

Background technology

Motor stator winding coils are divided into two kinds of structure types of distributed winding and centralized winding.Asynchronous motor is more Number is using distributed winding, brushless direct current motor（BLDC）And permasyn morot（PMSM）Using centralized winding.Point Cloth winding processing technology is complicated, and centralized winding processing technology is simple.The phase insulation of centralized winding is than distributed winding Phase insulation intensity it is high.The winding overhang length of centralized winding is shorter than the winding overhang length of distributed winding.Shorten around Group tip lengths can reduce stator winding copper loss, improve motor efficiency.

Monopole asynchronous motor and threephase asynchronous can simplify processing technology, reduce according to centralized winding Cost, improves motor efficiency at the phase insulation intensity for reducing stator winding copper loss, improving winding.Monopole asynchronous motor is wanted Ask and start winding and Working winding spatially by ninety degrees electrical angle, monopole asynchronous motor according to centralized winding, Pole-changing windings are cannot achieve, especially quadrupole/sextupole pole-changing windings monopole asynchronous motor, motor poles number when the slow-speed of revolution Ratio with motor poles number when high rotating speed is not integral multiple, and the prior art cannot achieve pole-changing windings.According to centralization Winding realizes quadrupole/sextupole pole-changing windings monopole asynchronous motor, then the motor can be widely applied for kitchen ventilator, electric wind Fan, exhaust fan, air-conditioning the household electrical appliance such as outdoor fan drive motor on.

Common brushless direct current motor and common permasyn morot are using centralized winding and p-m rotor.It is concentrating In the winding process of formula winding, the width of rebate of stator core wire casing cannot be too small, otherwise centralized winding can not be wrapped in On stator core magnetic pole.If the width of rebate of stator core wire casing is larger, the cogging torque of motor can increase, to increase Generator loss reduces motor performance.Therefore common brushless direct current motor and common permasyn morot majority use Fractional-slot winding reduces cogging torque.The major defect of fractional-slot winding is：Slot number has hard constraints, armature anti-with selection of number of poles It answers magnetomotive force to contain a large amount of harmonic waves, rotor eddy current loss and noise can be caused.If there is a kind of motor stator technology, do not influencing Under the premise of centralized winding technique processing, reduce the width of rebate of stator core wire casing or the notch of stator core wire casing Width is zero, i.e., the stator core wire casing is closed slot, then while reducing cogging torque, brushless direct current motor or permanent magnetism Synchronous motor can use integer slot winding, slot number and pole when increasing brushless direct current motor or permasyn morot design Several ranges of choice, and improve motor performance.

The stator core wire casing of asynchronous motor will produce slot ripples, and harmony wave generates additional torque, causes electromagnetism Vibration and noise.The method of asynchronous motor generally use rotor chute, the electricity for making harmony wave incude in rotor bar Kinetic potential is partially offset, and reduces the additional torque that harmony wave generates.Therefore, reduce asynchronous motor stator winding slot of core The width of rebate of width of rebate or stator core wire casing is zero, i.e., the stator core wire casing is closed slot, is conducive to asynchronous electricity Motivation reduces the additional torque that harmony wave generates, and improves motor efficiency.
