Description
Technical field
The utility model relates to motor.
Background technology
Motor can produce a large amount of heats when work, as can not timely the heat that produces being shed, then can affect the life-span of motor, even may motor damage.Existing motor mainly comprises stator and rotor, at the both ends of stator end cap is installed, and in order to realize heat radiation, then is positioned at stator at rotor fan is installed, and under the effect of fan, meeting forms distinguished and admirable in stator, thereby realizes heat radiation.Above-mentioned radiating mode is for heavy-duty motor, and heat radiation is slow, and therefore, radiating effect is bad.
Summary of the invention
The purpose of this utility model provides a kind of motor with inside and outside two wind path structures of good heat dissipation effect.
For achieving the above object, a kind of motor with inside and outside two wind path structures comprises stator, rotor, front end housing and rear end cap; Stator comprises housing and stator module, and stator module is installed in the housing; Rotor comprises rotating shaft and rotor assembly, and rotor assembly is installed on the rotating shaft; Front end housing is installed in the leading section of housing; Rear end cap is installed in the rearward end of housing; Be provided with radiating ribs at the housing outer wall; Be positioned at the housing leading section at rotating shaft the first fan is installed, be provided with interior air channel in the radiating ribs, the leading section of housing is provided with the first air inlet that is communicated with enclosure interior and interior air channel, and the rearward end of housing is provided with the first air outlet that is communicated with enclosure interior and interior air channel; Be provided with the second fan outside rotating shaft is positioned at rear end cap, is provided with the second air outlet between described rear end cap and the housing, be provided with the second air outlet at back cover, form outer air duct between the adjacent radiating ribs, described outer air duct and second goes out the second air outlet and is communicated with.
As improvement, has air-vent on the blade of the first fan.
The operation principle of said structure motor is: when machine operation, rotating shaft drives the first fan and the rotation of the second fan, under the effect of the first fan, the motor internal air is from first air inlet in stator, rotor air channel in the first fan is pressed into the drive end radiating ribs, by entering motor internal by anti-drive end the first air outlet behind the interior air channel, thereby realize circulating of motor body inner air, the expanded motor internal heat is to the ability of radiating ribs radiation; By anti-drive end the second fan air is sucked from motor back cover the second air inlet, flow out through the second air outlet, flow through again the surface radiating muscle, greatly increased the towards periphery heat-sinking capability of environment of radiating ribs, thereby the realization high-protection level, the designing requirement of low-temperature lifting motor.Therefore, motor of the present utility model, its good heat dissipation effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
