Abstract
The stator of the utility model is characterized in that including: the coil part for being wound with coil, the pole shoe portion for being installed on the groove portion of coil part and being installed on the end for the groove portion exposed from coil part.According to the utility model, it can be wound with the coil part of coil by the way that the groove portion of segmentation and pole shoe portion to be assembled in, reduce through leakage magnetic flux that groove portion occurs to improve motor performance.
Description
Technical field
The utility model relates to stator, more particularly to a kind of slot that segmentation is assembled to the coil part for being wound with coil
The stator for preventing motor performance from declining while portion and pole shoe portion.
Background technique
In the motor (or generator) such as industrial, special equipment is used, traction is used, loop wire distribution delineation is usually used
Motor stator form.Recently, the torque of motor, the demand of power are improved under limited size with generation,
Research improves the scheme of the coil fill-in ratio of stator.
Coil fill-in ratio indicates the groove area of stator and the area ratio of coiled coil, and fill-in ratio is higher, then motor
Size can be made to it is smaller to improve energy efficiency.
Linea angulata hairpin (section) coil stator is the effective scheme for improving coil fill-in ratio, is by the linea angulata of multiple hair-pin shapeds
Coil is inserted into stator core, and is welded in the end turn side opposite with direction of insertion to manufacture the side of required winding
Method.Linea angulata reduces dead space than loop wire, therefore fill-in ratio increases, and is able to use thick linea angulata, so as to reduce coil
Covering amount improves fill-in ratio.But for manufacturing engineering, need to weld multiple coils to youngster, it is therefore desirable to take off to cladding
Skin, welding form the engineerings such as other insulating coating, hardening insulating coating in weld part.In order to reduce welding engineering as far as possible,
It has developed and linea angulata coil is continuously formed into wave winding (wave winding) or lap winding (lap wound on other fixture
Winding), the scheme etc. that the stator core of segmentation is assembled in after fixture winding manufacture stator is unloaded.This scheme can subtract
Few coil pad, therefore weld correlation engineering and be simplified, there is remarkable result to product price is reduced.But in order to assemble volume
Around linea angulata coil and segmentation iron core, separation iron core can only be assembled on the outside of the big coil of coil spacing, therefore should be manufactured into
The tooth end of iron core does not have the opening type groove (open slot) of pole shoe (shoe).
Compared with the motor with pole shoe, it is applicable in that leakage magnetic flux of the motor of open type groove in gap be bigger and flux path
Diameter is elongated, therefore has that torque ripple is big, is difficult to the problem of reducing the harmonic wave of counter electromotive force.To need to solve these problems.
The background technique of the utility model is disclosed in Korean Patent Laid 10-2015-0012358
(2015.02.04 is disclosed, denomination of invention: the coil windings method of stator).
