It is reduced at electric efficiency, vibrating noise increases, and safe life shortens.Problem above is solved, increase stator punching is generally required
The width in yoke portion, the i.e. outer circle of stator core can increase the material cost of motor manufacturing again in this way.
Invention content
The object of the present invention is to provide a kind of stator cores of novel permanent-magnet motor, and stator core is made to be become from dissipating state structure
Overall structure, stator core integral strength are improved, are unlikely to deform, can be every magnetic, and leakage field, does not increase the radiating surface of stator core
Product improves heat-sinking capability, reduces motor temperature rise, improves electric efficiency and safe life, reduces motor oscillating and noise.While by
It is overall structure in stator core, stacking factor improves, and heat dissipation effect improves, and efficiency improves, and stator core outer circle becomes smaller, and reduces
Motor material cost.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
A kind of stator core of novel permanent-magnet motor, include by multi-disc stator punching laminate the formed body formed, be anchored on it is described
The non-magnetic alloy cavity of entirety of the outside portion circumferential surface and both ends yoke end surface of formed body.
Preferably, the non-magnetic alloy cavity of the entirety is structure as a whole, and is integrally formed using fastening and edging pressure.
Preferably, the non-magnetic alloy cavity of the entirety includes correspondingly in conjunction at formed body both ends yoke portion end
Engaging portion on face.
It is highly preferred that the width of the engaging portion is not more than the width in yoke portion.
It is highly preferred that the engaging portion is distributed with the formed body coaxial inner conductor, the thickness of the engaging portion is not more than
3mm。
Preferably, the non-magnetic alloy cavity of the entirety is distributed with the formed body coaxial inner conductor.
Preferably, the yoke portion width of the stator punching is smaller by 15% than conventional.
Preferably, the formed body is chute stator iron core, and the depth of parallelism and verticality of the chute stator iron core exist
Within 0.05mm.
Preferably, the non-magnetic alloy cavity of the entirety is the casing of magneto.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：It is of the invention a kind of new
The stator core of type magneto is anchored on the entirety of the outside portion circumferential surface and both ends yoke end surface of formed body by setting
Non-magnetic alloy cavity makes stator core become overall structure from dissipating state structure, stator core integral strength is made to improve, not variable
Shape increases the heat dissipation area of stator core every magnetic and not leakage field, improves heat-sinking capability, reduces motor temperature rise, improves electric efficiency
And safe life, reduce motor oscillating and noise.Simultaneously because stator core is overall structure, stacking factor improves, heat dissipation effect
Fruit is improved, and efficiency improves, and stator core outer circle becomes smaller, and reduces motor material cost.
