Description
Technical field
The utility model relates to a kind of motor, specifically a kind of built-in aerofoil fan monopole asynchronous motor.
Background technology
At present, the asynchronous motor of nature air swept type is progressively eliminated, and the employing totally enclosed type, rely on external fan that the heat that is delivered to shell in the machine is cooled off, though strengthened the safety used, enlarged the scope of application, because of its radiating efficiency poor, temperature rise can not get effectively reducing, and causes the electromagnetic material of motor to be not fully utilized and causes waste.Though in the motor of some phase-wound rotors, adopt built-in fans, generally believe that this is for effectively reducing the way of rotor winding temperature rise, be not to be able to and for it.Then none adopts built-in fan for the temperature rise that reduces the single-phase squirrel-cage asynchronous motor winding of small-power.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides a kind of energy consumption to reduce the built-in aerofoil fan monopole asynchronous motor that amplitude is big, sound attenuation is remarkable, cost is low, cooling effectiveness improves.
The technical scheme that its technical problem that solves the utility model adopts is: rotor is fixed on the interior rotation axis of casing, stator be arranged on rotor around, the top of casing is provided with terminal box, the rear and front end of casing is respectively arranged with front end housing and rear end cap, rotation axis links together by bearing and front end housing and rear end cap, aerofoil fan is arranged on the rotation axis of rear end cap inboard, is provided with air duct between stator and the casing inner wall.
The inboard of front end housing is set with signal receiver, and the rotation axis of front end housing inboard is provided with signal transducer; The outside of rear end cap is fixed with air regulator; Motor can be made single shaft and stretch, and also can make twin shaft and stretch motor, thereby realize a tractor serves several purposes; The power of electric motor scope is 1500W～4000W.
Built-in aerofoil fan monopole asynchronous motor of the present utility model is compared with prior art, have reasonable in design, simple in structure, big, the characteristics such as sound attenuation is remarkable, cost is low, cooling effectiveness raising of energy consumption reduction amplitude, thereby, have good value for applications.

Embodiment
Explain below with reference to Figure of description built-in aerofoil fan monopole asynchronous motor of the present utility model being done.
Built-in aerofoil fan monopole asynchronous motor of the present utility model, its structure comprises casing 1, rotation axis 5, stator 7 and rotor 8, rotor 8 is fixed on the rotation axis 5 in the casing 1, stator 7 be arranged on rotor 8 around, the top of casing 1 is provided with terminal box 6, the rear and front end of casing 1 is respectively arranged with front end housing 9 and rear end cap 3, rotation axis 5 links together by bearing 12 and front end housing 9 and rear end cap 3, aerofoil fan 2 is arranged on the rotation axis 5 of rear end cap 3 inboards, is provided with air duct 13 between stator 7 and casing 1 inwall.
The inboard of front end housing 9 is set with signal receiver 10, and the rotation axis 5 of front end housing 9 inboards is provided with signal transducer 11; The outside of rear end cap 3 is fixed with air regulator 4.
During work, built-in aerofoil fan dispels the heat to motor by air duct is more effective, make motor under the situation of same temperature rise, the amplitude that the motor that the motor of built-in aerofoil fan dispels the heat than external fan can better cut down the consumption of energy, reduce the cost of motor, improve the operating efficiency of motor.
Built-in its processing and fabricating of aerofoil fan monopole asynchronous motor of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Motor can be: the 2200W twin shaft is stretched or single shaft is stretched monopole asynchronous motor, the 2700W twin shaft is stretched or single shaft is stretched monopole asynchronous motor, the 3000W twin shaft is stretched or single shaft is stretched monopole asynchronous motor, the 3700W twin shaft is stretched or single shaft is stretched monopole asynchronous motor, the 4000W twin shaft is stretched or single shaft is stretched monopole asynchronous motor.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
