Abstract
Disclosed in the utility model is an external rotor motor comprising a rotor, a stator, and a rotating shaft. The rotating shaft is fixed at the center of the stator and cooperates with the rotor by a bearing installed at the rotor. The rotor includes two portions: a rotor sleeve and an end cover; a first sealing ring is arranged between the rotor sleeve and the end cover; and a second sealing ring is arranged between the rotating shaft and the end cover. One end of the rotating shaft extends out of the end cover for fixing. According to the scheme, the rotor is divided into two portions and the stator is enclosed between the two portions; and the sealing rings are used for sealing, thereby realizing the waterproof and dustproof performances. Moreover, a support seat is also arranged and is used for fixing the motor. Therefore, the provided external rotor motor is suitable for various occasions.
Description
Technical field
The utility model relates to a kind of motor, especially a kind of external rotor electric machine.
Background technology
Existing motor product, by the arrangement of stator and rotor, can be divided into inner rotor type motor and external-rotor motor.Inner rotor type motor rotor is rotatably installed in stator interior, and external-rotor motor rotor is rotatably installed in stator outside.External rotor electric machine is in the application of a lot of fields, due to its special structure, causes its sealing, water proofing property poor.
Utility model content
The utility model technical issues that need to address are to provide a kind of good seal, external rotor electric machine that water resistance is superior.
For addressing the above problem, technical solution adopted in the utility model is: a kind of external rotor electric machine, comprise rotor, stator and rotating shaft, and its shaft is fixed on stator center, and coordinate with rotor by being arranged on epitrochanterian bearing, described rotor is divided into two parts, and a part is rotor cover, and a part is end cap, between rotor cover and end cap, the first sealing ring is set, the second sealing ring is set between rotating shaft and end cap, and end cap is stretched out in rotating shaft one end, for fixing.
The end that end cap is stretched out in described rotating shaft is provided with hold-down support, and bearing and rotating shaft adopt spline joint.
The beneficial effect that adopts technique scheme to produce is: the utility model, by rotor is divided into two parts, is trapped among stator between two parts, seals water proof and dust proof by sealing ring; This novel bearing that further increases, for fixing of motor, is applicable to various occasions.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1, stator, 2, rotor, 3, end cap, 4, bearing, 5, rotating shaft, the 6, second sealing ring, the 7, first sealing ring.
Embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail: as shown in Figure 1, this Novel external rotor motor comprises rotor 2, stator 1 and rotating shaft 5, its shaft 5 is fixed on the center of stator 1, and coordinate with rotor 2 by the bearing being arranged on rotor 2, described rotor 2 is divided into two parts, a part is rotor cover, a part is end cap 3, on rotor cover and end cap, a set of bearing is respectively set, between rotor cover and end cap 3, the first sealing ring 7 is set, the second sealing ring 6 is set between rotating shaft and end cap 3, and end cap 3 is stretched out in rotating shaft 5 one end, for fixing.
This is novel, and for convenient fixing, the end of stretching out end cap 3 in rotating shaft is provided with hold-down support 4, and bearing 4 adopts spline joint to fix with rotating shaft 5, certainly, also can adopt the modes such as bearing pin, screw thread.When adopting hold-down support 4, the second sealing ring 6 also can be arranged between bearing 4 and end cap 3.
