The utility model is described further with reference to the accompanying drawings and examples：
Referring to figs. 1 to Fig. 2, a kind of motor inner-rotary type heat dissipation wind channel structure of the utility model includes the machine of hollow tubular
The stator 2 of seat 1, press fitting inside engine base 1 and the rotor 4 with fan blade 3 inside stator 2,1 inner wall of the engine base are equipped with more
Spiral or inclined first ventilation slot 5, spiral or inclined direction are consistent with the direction of rotation of rotor 4；First ventilation slot 5 it
Between protrusion part stator 2 is fixed in, i.e. the first ventilation slot 5 is positioned at engine base 1 and stator between, when the rotation of rotor 4, fan blade
3 follow its synchronous rotation, ducting fanned air to flow to form wind, and wind flows to air outlet by the first ventilation slot 5, to be 2 He of stator
1 inner wall of engine base cools down.By by 5 spiral of the first ventilation slot or being inclined at 1 inner wall of engine base, make the fixed motor air duct turned to
Optimized, reduce air duct angle whirlpool phenomenon, reduced windage, be effectively increased 2 outer ring of stator and be exposed at the first ventilation slot 5
Area so that more preferably, Wen Shenggeng is low for motor radiating.In addition, the inner wall gross area setting of the protrusion part between the first ventilation slot 5
Air-cooled efficiency is improved, Wen Sheng is effectively inhibited to further increase draught area for the gross area less than the first ventilation slot 5.
Preferably, the angle of inclination of first ventilation slot 5 is arranged according to the rotating speed direct proportion of rotor 4, the fan blade 3
