Being labeled as in accompanying drawing: 1-support, 2-drive end bearing bracket, 3-rear end cap, 4-stator, 5-rotor, 6-rotating shaft, 7-air filter, 8-heat-conducting resin, 9-fan, 10-rotor front end face.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described, but is not intended as the foundation to this utility model restriction.
Embodiment.Asynchronous machine, is constituted as it is shown in figure 1, include support 1, support 1 be respectively provided on two sides with the drive end bearing bracket 2 with gas channel, rear end cap 3, the inside of casing 1 is provided with mutually corresponding stator 4, rotor 5 and rotating shaft 6.It is characterized in: the inner webs face of described rear end cap 3 is provided with air filter 7；Described rotor 5 is with heat-conducting resin 8 embedding (heat-conducting resin 8 can be fire resistant epoxy type heat-conducting glue)；In described rotating shaft 6, between drive end bearing bracket 2 and rotor 5, it is provided with fan 9, the distance of described fan 9 and drive end bearing bracket 2 is 1.5～2cm, the distance of described fan 9 and rotor 5 is 2～2.5cm, the wind direction of described fan 9 points to drive end bearing bracket 2, and (wind direction of fan 9 refers to fan 9 when working, the direction of air flowing), the diameter of described fan 9 is 0.6～0.8 times of the diameter of rotor 5, as preferably, the distance of described fan 9 and drive end bearing bracket 2 is 1.8cm, the distance of described fan 9 and rotor 5 is 2.2cm, the wind direction of described fan 9 points to drive end bearing bracket 2, the diameter of described fan 9 is 0.75 times of the diameter of rotor 5.
