By adopting technique scheme, first louvre and the second louvre are by connecting hole mutual conduction, the thermal current that rotating shaft and rotor core produce can be made to have better mobility, this thermal current can be passed to rotor exterior by the first louvre and the second louvre, be passed to the external world by ventilation hole, thus play radiating effect.
The utility model is set to further: rotor core is provided with the shaft hole worn for rotating shaft, shaft hole inwall offers groove, and in rotating shaft, respective slot is provided with raised line.
By adopting technique scheme, the inwall of shaft hole arranges groove and raised line is set in rotating shaft, to rotor core and rotating shaft be located, with the conducting facilitating connecting hole, thus ensure the moment conducting of the first louvre and the second louvre, and then ensure effective air flow property, play radiating effect.
The utility model is set to further: the first louvre is uniformly distributed in the surrounding of shaft hole.
By adopting technique scheme, the first louvre being evenly distributed in the surrounding of shaft hole, being to make the uniformity of heat dissipation ventilation better, thus increasing the effect of heat radiation.
Compared with prior art, the utility model has the advantage of: in rotor core, offer multiple first louvre, rotating shaft offers the second louvre, louvre is provided with some fresh air inlets, and the first louvre and the second louvre mutual conduction, therefore this rotor body rotate and heat production time, the heat that rotating shaft and rotor core produce not only can be delivered in air-flow, and arrange due to the mutual conduction of the first louvre and the second louvre, just gas flow phenomenon can be produced in the body of rotor, simultaneously owing to being provided with blade in the opening part correspondence of the first louvre and the second louvre, therefore under blade auxiliary is blown, air-flow circulation in the entire rotor can become stronger, thus thermal current can under the mobilization of gas, circulate away from rotating shaft and rotor core, and from the ventilation hole support, be passed to the external world, thus serve the fast cooling effect of motor.
