Abstract
The invention discloses a novel three-phase asynchronous motor which is characterized by comprising a stator, a rotor and a housing, wherein an axial air hole is formed on the side wall of the housing; a radiating rib is arranged outside the housing; the stator is fixed in the housing; the rotor is arranged at a hollow position in the center of the stator through a rotary shaft and a sealing housing; one side of the rotary shaft extends out of the sealing housing to be connected with a fan blade which is covered by a fan blade shade; a port of the fan blade cover is in sealing connection with the outer side of the housing, and an air inlet is formed at the end of fan blade cover. According to the utility model, during working, the air from the fan blade intensively blows through the axial air hole, at a uniform speed, so that the convection is full, the radiating effect is good, and the purposes of simplicity, economy and appealability are achieved. Therefore, the novel three-phase asynchronous motor has huge economic and social benefits, and also has a wide market prospect.
Description
Technical field:
The present invention relates to a kind of motor, particularly a kind of novel threephase asynchronous machine, the temperature rise in the time of can reducing work, cost simple in structure is low.
Background technology:
Along with the progress and the expanding economy in epoch, the economic construction develop rapidly, motor as the power source application more and more widely, asynchronous motor be use in all kinds of motor the widest, that requirement is maximum is a kind of.In China; The power consumption of asynchronous motor accounts for more than 60% of total load, and particularly threephase asynchronous machine occupies critical role, generally is applied on the large industry equipment; The high power epistasis of power can be stablized and obtained generally assert, for huge contribution has been made in economic development.This threephase asynchronous machine merit all can be generated heat during work, and this just requires that cooling mechanism will be arranged, otherwise for a long time at high temperature the work drive motor insulating barrier can accelerate the burn-in effects electrical machinery life; And even burn-down of electric motor, in order to give the motor cooling, the threephase asynchronous machine temperature all is to dispel the heat through on housing, setting up radiating ribs; Install fan additional in motor one side and strengthen wandering thermal velocity; But this structure wind direction is not concentrated a little less than the strong air opening end far away of the nearly air opening end of surface of shell convection current, has influence on its radiating effect, and influence is bigger when particularly under hot environment, working; This radiator structure awaits improving, and improves the threephase asynchronous machine runnability.
Summary of the invention:
In order to address the above problem, the present invention provides a kind of novel threephase asynchronous machine, and is simple in structure, good heat dissipation effect.
The technical scheme that the present invention adopts is: a kind of novel threephase asynchronous machine comprises it is characterized in that comprising stator, rotor and housing that housing sidewall is provided with axial wind hole; Stator is fixed in the housing; Rotor is arranged on the stator center hollow position through rotating shaft and capsul, and rotating shaft one side is extended capsul and is connected with flabellum, and flabellum is provided with the flabellum cover outward; Flabellum cover port is connected with hull outside is airtight, and flabellum cover termination is provided with air inlet.
Said housing is provided with radiating ribs outward.
