Abstract

Stator with no yoke type revolving-armature type magneto, belongs to magneto field.Solves the problems such as existing permanent magnet of permanent magnet motor is easy to fall off, motor weight weight.It includes stator, rotor, casing, left end cap, right end cap, shaft and bearing.The utility model changes the stator and rotor arrangement of conventional motors, the form that original fixed armature, p-m rotor rotate the mode that permanent magnet is fixed, armature rotates has been changed to, casing is the stator of motor, permanent magnet is pasted onto using adhesive on internal side of shell wall, eliminates the stator yoke of traditional structure.It is mainly used for solving the problems, such as that permanent magnet fixes difficult, raising motor performance, reduction motor weight and cost.

Description

Stator with no yoke type revolving-armature type magneto
Technical field
The utility model is related to magneto field, more particularly to a kind of revolving-armature type magneto.
Background technology
For most of magnetoes, the form that armature is fixed, p-m rotor rotates all follow.In this structure Under, since permanent magnet is pasted onto on rotor using adhesive, when motor is rotated, not only easily make permanent magnet It comes off and motor heavier-weight, is unfavorable for the operation of magneto.
Magneto is compared to conventional induction machine, if being affectedly bashful to the design of the anti-dropout of permanent magnet bad, will give electricity Machine brings extremely serious influence, how to solve the problems, such as that this problem becomes puzzlement design of electrical motor personnel.In addition, motor uses Person is always wanted in the case where obtaining equal performance, the motor that use is small, light-weight.
Invention content
In order to solve the problems such as existing permanent magnet machine rotor permanent magnet is easy to fall off, weight weight, the utility model provides one Kind stator with no yoke type revolving-armature type magneto.
Stator with no yoke type revolving-armature type machine changes the stator and rotor arrangement of conventional motors, by original fixation Armature, p-m rotor rotation form be changed to permanent magnet fix, armature rotation mode, it include stator, rotor, shaft and Casing further includes left end cap, right end cap and bearing.
Armature winding is placed according to certain arrangement mode in rotor.
Stator is casing, and permanent magnet is pasted onto using adhesive on internal side of shell wall, eliminates traditional motor stator Yoke structure.
Rotor is fixedly connected by being interference fitted with shaft.
There are air gaps between motor stator and rotor.
The motor stator, rotor, left end cap, right end cap are coaxial.
The advantageous effect that the utility model is brought is the stator with no yoke type revolving-armature type permanent magnetism that the utility model is proposed Permanent magnet is affixed directly to i.e. permanent magnet on internal side of shell wall and is not involved in rotary motion, solves its caducous difficulty by motor Topic, while the stator yoke of traditional structure is eliminated, not only eliminating the heat of stator yoke loss and motor generation can lead to It crosses casing and directs out diffusion, improve the performance of motor.
Weight of the motor described in the utility model because without stator yoke, reducing motor, save material and technique very Simply, have to the cost of motor and largely weaken.
