Preferably, sliding shoe is set between the inner surface of the rotor and four limited blocks.

Beneficial effect

The utility model provides a kind of double-deck wind path of high-speed motor iron core.Have it is following the utility model has the advantages that

The double-deck wind path of the high-speed motor iron core, by having apparent gap between external and shell, so that stator is interior Outside can produce air flowing, does not contact directly with casing, forms the double-deck wind path structure, the double-deck wind path structure is set Meter provides more approach to the trend of wind, very well so that stator component increases one times with the area that air directly contacts Improve the heat-exchange capacity of motor internal parts, to realize more excellent heat dissipation effect, the optimization to motor performance There are very active influence, while the space of stator component inside hollow out, in addition to the design of ventilation, while can also be used as circuit The parking space of the bigger electronic component of circuit board upper volume, more optimized structure, the double-deck wind path after plate and motor body assembly Ventilation is more preferable, and heat dissipation effect is more preferable.
