Description
Technical field
This utility model belongs to motor stator technical field, refers in particular to a kind of Novel stator having from magnetic conduction function.
Background technology
At present, the existing permanent-magnet brushless dc motor for electric automobiles, the slot wedge that its stator uses is most
For common isolation material slot wedge, it is arranged on motor in running with the stator of this structure, stator iron core tooth produces
Raw magnetic force component makes iron core produce vibration deformation, and the root portion bending of stator core causes local vibration to deform, finally
Causing electric and magnetic oscillation and noise that motor is bigger, isolation material slot wedge can produce bigger cogging torque, makes motor run
Journey produces bigger commutation noise and electric current, makes the electromagnetic noise of motor increase and caloric value increases, affect the performance of motor.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel stator having from magnetic conduction function, stationarity when stator runs
Good, noise, vibrate little, effectively reduce the electric current of motor, decrease the heat that motor produces, improve the performance of motor, with
Time decrease the raw material usage amount of stator core, reduce cost.
The purpose of this utility model is achieved in that
A kind of Novel stator having from magnetic conduction function, including iron core and coil, between the medial wall circumference of described iron core
Every being provided with tooth, more than one tooth is provided with more than one groove towards the end face of core center, two adjacent teeth it
Between be formed with wire casing, described coil is arranged in wire casing, and more than one wire casing is provided with envelope in the notch of core center
Block the magnetic conduction slot wedge of notch.
In technique scheme, described groove include cross section be square groove or/and cross section be square and
The groove of the bottom rounding off of square groove.
In technique scheme, described wire casing is provided with limit convex edge towards the two side of the notch of core center,
Described magnetic conductive groove wedge is arranged on limit convex along the wire casing of inner side.
This utility model highlights and useful having the technical effect that compared to existing technology
1, this utility model is by arranging groove on the end face of the tooth on iron core, has reached to increase the number of times of groove moment
Thus reduce the effect of groove moment, decrease the raw material usage amount of stator core simultaneously, reduce cost, make motor run
Time stationarity good, noise, vibrate little, magnetic slot-seal be set in wire casing simultaneously and substitute traditional insulating slot wedge, improve magnetic conduction
Effect, effectively reduces the electric current of motor, decreases the heat that motor produces, improves the performance of motor.
Accompanying drawing explanation
Fig. 1 is to arrange the cross-sectional view that cross section is square groove on the tooth of iron core of the present utility model.
Fig. 2 is to arrange cross section on the tooth of iron core of the present utility model to be square groove and cross section is square and square
The cross-sectional view of the groove of the bottom rounding off of groove.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 12:
A kind of Novel stator having from magnetic conduction function, including iron core 1 and coil, the medial wall circumference of described iron core 1
Being arranged at intervals with tooth 2, more than one tooth 2 is provided with more than one groove 3, at the end of tooth 2 towards the end face of core center
Arranging groove 3 on face and decrease the raw material usage amount of iron core 1, reduce cost, during operation, stationarity is good, noise, vibrate little, phase
Being formed with wire casing 4 between two adjacent teeth 2, described coil is arranged in wire casing 4, and more than one wire casing 4 is towards core center
Notch in be provided with the magnetic conduction slot wedge 5 blocking notch, magnetic conduction slot wedge 5 mainly by glass fabric, epoxy resin, iron powder and
Other additives form, and improve the magnetic conduction effect of stator, effectively reduce the electric current of motor, decrease the heat that motor produces
Amount, improves the performance of motor.
Above-mentioned groove 3 includes that cross section is that square groove is or/and cross section is that square and square groove bottom is round and smooth
The groove of transition.
Above-mentioned wire casing 4 is provided with limit convex along 6 towards the two side of the notch of core center, and described magnetic conduction slot wedge 5 sets
Putting in the wire casing 4 inside limit convex is along 6, magnetic conduction slot wedge is stuck in wire casing by coil and limit convex along 6.
Above-described embodiment is only preferred embodiment of the present utility model, limits protection model of the present utility model the most according to this
Enclose, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, protection of the present utility model all should be covered by
Within the scope of.
