Work, the air-flow of fan reach at fore bearing by guide vane, so as to be radiated to fore bearing, reduce bearing temperature, extend
Bearing life, avoid fore bearing and damaged because temperature is too high, guide vane is also used as the protection structure of motor in addition, structure
Simply, it is reasonable in design, it is novel.
A kind of asynchronous ac motor provided by the utility model, including：Motor body, the motor body end are wind
Fan cover, is fan in the fan guard, is provided with gap between the fan guard and motor body, the motor body it is another
To hold as fore bearing, be socketed with guide vane outside the motor body, one end of the guide vane is arranged on the upside of fan guard, and with
Fan guard is provided with gap, and the other end of the fan guard is arranged on the upside of fore bearing, wind is provided with the motor body
Cover fixing hole and guide vane fixing hole are fanned, the guide vane is fixed in one end of fan by fan fixing hole and nut, described
Guide vane is fixed in one end of fore bearing by guide vane fixing hole and nut.
Preferably, the motor body bottom is fixedly connected with motor base.
Preferably, the guide vane is made up of aluminum alloy materials.
Preferably, pad is provided with by nut on the fan guard fixing hole and guide vane fixing hole, the pad is set
Put between motor body and guide vane.
Preferably, the fan guard fixing hole and guide vane fixing hole are two.
The beneficial effects of the utility model are：Fan work in fan guard, before the air-flow of fan reaches by guide vane
At bearing, so as to be radiated to fore bearing, bearing temperature is reduced, extends bearing life, avoids fore bearing because temperature is too high
And damage, guide vane is also used as the protection structure of motor in addition, simple in construction, reasonable in design, novel.
