The notch in motor stator slot is set, the other end connects electric machine casing, and the radial direction radiating fin cross section is circle, diameter etc.
In motor slot width；The electric machine casing is hexagon, and the circumferential direction radiating fin is circumferentially uniformly arranged along electric machine casing, and
Vertical with the radial radiating fin, the circumferential direction radiating fin includes inner circumferential radiating fin and external circumferential radiating fin
Piece, the length of inner circumferential radiating fin are the 0.8 of external circumferential radiating fin length, and the stator outer diameter is most short away from shell
The ratio between distance and stator diameter are 0.05-0.1.
The cross-sectional area of the radial direction radiating fin radially gradually increases.The radial direction radiating fin is by high heat conduction
Permeability magnetic material is made.The radial direction radiating fin is to be made of copper.The radial direction radiating fin is arranged with piecemeal iron core junction
There are protrusion, piecemeal iron core to be correspondingly arranged on the groove engaged with protrusion.The inner circumferential radiating fin away from stator outer diameter away from
From with distance ratio of the external circumferential radiating fin away from electric machine casing be 0.55-0.65.
Illustrated embodiment of the present invention has the advantages that：It is arranged in motor by the way that radial radiating fin one end is arranged
The notch of stator slot, the other end connect electric machine casing, and radial radiating fin is made of high heat conduction permeability magnetic material, by the heat of stator
Amount is directly delivered to shell, and the length for improving heat dissipation effect, while inner circumferential radiating fin being arranged is external circumferential heat dissipation
The shortest distance of the ratio and stator outer diameter of finned length away from shell and the ratio of stator diameter can reduce stator in pole body height
The apparent size on direction is spent, circumferential radiating fin is increased, to improve the heat dissipation effect of motor while improve power density,
The air-flow that heat utilization fan generates on radiating fin is taken out of inside motor, can propose the heat dissipation effect of small-scale high rotational speed motor.
