Description
Technical field
The utility model belongs to technical field of motors, is specially a kind of ventilation stator core.
Background technology
Motor is generally made up of stator, rotor and other annex, and stator comprises stator core, stator core generally by have insulating barrier punching silicon-steel, be overrided to form, have equally distributed groove in inner circle unshakable in one's determination punching, in order to embed stator winding.One group of stator core sheet is stacked with regulation sheet number, the peripheral part of magnetic piece duplexer is carried out to laser welding, welding can produce infringement to insulating barrier, reduces stator core quality; And existing radiating effect unshakable in one's determination is bad, affect the performance of whole motor.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is that design provides a kind of technical scheme of ventilation stator core simple in structure, and stator core is integral type structure, and the stator core quality making is good; And heat dissipating layer, ventilation hole are set, have further improved thermal diffusivity, stability, the reliability of motor, promoted the overall performance of motor.
Described one ventilation stator core, it is characterized in that comprising integrated stator core, stator core inner ring is uniform arranges one group of tooth utmost point portion, between tooth utmost point portion, stator core inner ring, curved portions is set, in each tooth utmost point portion, ventilation hole is all longitudinally set, tooth utmost point portion front portion longitudinally arranges one group of teeth groove, and stator core integral surface applies the insulating barrier that 0.1-0.3mm is set, and the surface of insulating layer of stator core outer wall applies 0.2-0.5mm heat dissipating layer is set.
Described one ventilation stator core, is characterized in that described ventilation hole cross section is for circle, triangle, square, rectangle or trapezium structure.
Described one ventilation stator core, the thickness that it is characterized in that insulating barrier is 0.15-0.25mm.
Described one ventilation stator core, the thickness that it is characterized in that heat dissipating layer is 0.3-0.4mm.
Above-mentioned a kind of ventilation stator core, stator core is integral type structure, the stator core quality making is good; And heat dissipating layer, ventilation hole are set, have further improved thermal diffusivity, stability, the reliability of motor, promoted the overall performance of motor.
Brief description of the drawings
