Abstract
The utility model discloses a split-type integrated external-rotor asynchronous motor, which mainly comprises a stator (3) and a shaft (4), wherein the shaft (4) is fixed inside the stator (3) through a bearing (8); and the split-type integrated external-rotor asynchronous motor is characterized in that a shell (1) for covering the whole stator (3) is also arranged on the shaft (4), and meanwhile, a rotor (2) which synchronously rotates along with the shell (1) is also arranged on the inner wall of the shell (1). The split-type integrated external-rotor asynchronous motor not only has a simple structure, but also has a low cost, the shell (1) and the rotor (2) are respectively and individually manufactured, and reinforcing ribs at the supporting end of the rotor (2) are conveniently arranged inside the motor, so that the split-type integrated external-rotor asynchronous motor is suitable for being popularized and applied.
Description
Technical field
The utility model relates to a kind of motor, specifically is meant a kind of split type whole external rotor asynchronous machine.
Background technology
At present, general asynchronous machine is integral type external rotor asynchronous machine, what the shell of known integral type external rotor asynchronous machine (being mainly used in blower fan) and rotor bar used is commaterial, and it is as a whole to adopt the die casting mode to be cast into, so integral type external rotor asynchronous machine by name.Because the shell of integral type external rotor asynchronous machine and rotor form an integral body by die casting, so the reinforcement of rotor supports end can not be arranged on the inside of motor, can only be arranged on the outside of motor, and the outside of support end also is the air intake of blower fan, reinforcement then can produce disturbance to air intake, thereby the noise of blower fan is increased; Simultaneously, reinforcement also produces windage, and the wind frictional dissipation is increased, thereby reduces the efficient of motor and blower fan.
The utility model content
The purpose of this utility model is to overcome the shell of present integral type external rotor asynchronous machine and rotor by being cast into an integral body, thereby the reinforcement that makes the rotor supports end can only be arranged on the exterior defects of motor, provide a kind of not only simple in structure, and shell and rotor can make respectively, thereby make reinforcement can be arranged on the split type whole external rotor asynchronous machine of motor internal.
The utility model is achieved through the following technical solutions: split type whole external rotor asynchronous machine, mainly by stator, form at the axle of this stator interior by bearing fixing, on this, also be provided with the shell of the whole stator of cover cap, on the inwall of this shell, also be provided with the synchronous rotor rotated of shell simultaneously.
Further, on this stator, also the end cap that is complementary with shell is arranged by bolt.
Further again, described shell adopts metal material to be made.
In order to satisfy different needs, described shell casting or stretching form.
In order to realize that better the utility model, described shell adopt plastic material to be made.
In order to ensure effect, described shell is directly injection-moulded on the rotor.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost.
(2) shell of the present utility model and rotor are made separately respectively, thus the convenient inside that reinforcement is arranged on motor.
(3) shell of the present utility model can use the material different with rotor, therefore makes things convenient for the user to select different materials according to different needs.
(4) it is injection molded that shell of the present utility model adopts plastic cement material, therefore reduced the cost of raw material and processing cost.
Description of drawings
Fig. 1 is the structural representation of whole external rotor of the present utility model.
Fig. 2 is an overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the utility model is fixedly linked by stator 3, the bearing 8, an end and the bearing 8 that are fixed on stator 3 inside, the other end stretches out in the axle 4 of stator 3 outsides, and is fixedly linked with this other end of 4 and can constitutes with the external rotor of these 4 rotations synchronously.For axle 4 and bearing 8 are linked together more closely, between these 4 two surfaces of matching, also be provided with collar 7 with bearing 8.As shown in Figure 2, described external rotor then comprises shell 1 and the rotor 2 that is fixed on shell 1 inwall.In order to ensure result of use, these rotor 2 preferential do as one likes can be made by the die casting mode by good fine aluminium or aluminium alloy.
Described shell 1 is made into the semi-closed structure with opening end by metal material, alloy material or plastic material by the mode that stretches or cast.Can rotate around stator 3 in order to ensure whole external rotor, so the centre of shell 1 need be fixed on the axle 4.2 of described rotors are fixed on the inwall of shell 1 opening end, thereby when guaranteeing shell 1 with axle 4 rotation synchronously, the magnetic field that this rotor 2 can cutting stators 3 be produced.
When this shell 1 used metal material or alloy material to make, it also was provided with reinforcement 9 simultaneously by stretching or casting on the inwall of this shell 1 blind end.During combination, with shell 1 by its opening end with rotor 2 cover caps portion within it, the inwall of shell 1 opening end is cooperated with the outer wall of rotor 2, and with shell 1 hot jacket on rotor 2, thereby make shell 1 and rotor 2 be combined into a whole external rotor.
When this shell 1 uses plastic material, directly shell 1 is injection-moulded on the outer surface of rotor 2, perhaps, then shell 1 hot jacket is got final product on rotor 2 earlier with shell 1 injection mo(u)lding.9 blind ends that are arranged on shell 1 equally of reinforcement, and then rotor 2 and reinforcement 9 are wrapped in its inside by shell 1, make shell 1 and rotor 2 be combined into a whole external rotor.
In order to ensure safe handling, make whole external rotor form a sealed whole body, also be provided with the end cap 5 that is complementary with shell 1 at the openend of shell 1, this end cap 5 is connected on the stator 3 by bolt 6.
As mentioned above, just can realize the utility model preferably.
