Abstract
The utility model discloses a novel hollow-cup servo motor which comprises an output shaft and a housing. The housing is internally provided with a rotor. One end of the housing is provided with a front end cover, and the other end of the housing is provided with a back end cover. The front end cover and the back end cover are respectively provided with a bearing for an output shaft to pass through. The back end cover is provided with a commutator. The rotor comprises a rotation hub and an integrated coil winding connected with the rotation hub. The output shaft pass through the bearing of the front end cover, the rotation hub and the bearing of the back end cover in sequence. The hollow-cup servo motor utilizes the integrated coil winding, so that when the hollow-cup servo motor is used, the coil winding can bear large use intensity without getting loose; and the hollow-cup servo motor is good in stability, and can be widely used in high-intensity and frequently-used work places.
Description
Technical field
The present invention relates to electric tool technical field, refer in particular to a kind of novel drag cup servomotor.
Background technology
Drag cup motor has structurally been broken through the rotor structure form of conventional motors, the rotor structure of this novelty has thoroughly been eliminated because iron core forms the electric energy loss that eddy current causes, its weight and moment of inertia significantly reduce simultaneously, thereby have reduced the mechanical energy loss of rotor self.Obtained very big improvement because the structural change of rotor makes the service performance of motor, not only there is outstanding characteristics of energy saving, what is more important possessed iron core motor be beyond one's reach control and drag characteristics.But; hollow-cup motor is in the time manufacturing; cup rotor is that enamelled wire is turned to cup shape coil windings; again coil windings is glued, is welded on motor shaft, in the time that working strength is higher, affected by the factors such as stress, tightness, firm degree; easily loose, dimensional uniformity is poor; easily cause hollow-cup motor abnormal or damage, so this drag cup servomotor can only be applied in the place that environment is good, intensity is low, limitation is comparatively obvious.
Summary of the invention
The deficiency existing for above-mentioned prior art, the object of this invention is to provide a kind of novel drag cup servomotor, and it has advantages of to use and is suitable for high, the applied widely and good stability of intensity.
To achieve these goals, the technical solution adopted in the present invention is: a kind of novel drag cup servomotor, comprise output shaft and casing, in described casing, be provided with rotor, one end of described casing is provided with front end housing, the other end of described casing is provided with rear end cap, described front end housing and rear end cap are provided with for output shaft through bearing, described rear end cap is provided with commutator, described rotor comprises and turns hub and turn with described the integral type coil windings that hub is connected, described output shaft successively through the bearing of front end housing, turn the bearing of hub and rear end cap.
Preferably, described integral type coil windings comprises cup coil, and described cup coil is fixed by spraying resin bed.
Preferably, described resin bed is epoxy powder resin.
Preferably, described cup coil is equipped with soft magnetic bodies layer outward.
Adopt after said structure, the advantage that compared to the prior art the present invention had is: a kind of novel drag cup servomotor, comprise output shaft and casing, in described casing, be provided with rotor, one end of described casing is provided with front end housing, the other end of described casing is provided with rear end cap, described front end housing and rear end cap are provided with for output shaft through bearing, described rear end cap is provided with commutator, described rotor comprises and turns hub and turn with described the integral type coil windings that hub is connected, described output shaft successively through the bearing of front end housing, turn the bearing of hub and rear end cap; This drag cup servomotor is owing to having adopted integral type coil windings, thus in use, its coil windings can bear can not occur compared with large working strength loose, good stability, can be widely used in intensity high, use workplace frequently.

Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
A kind of novel drag cup servomotor as shown in Figure 1 to Figure 3, comprise output shaft 1 and casing 2, in described casing 2, be provided with rotor 3, one end of described casing 2 is provided with front end housing 4, the other end of described casing 2 is provided with rear end cap 5, described front end housing 4 and rear end cap 5 are provided with for output shaft 1 through bearing, described rear end cap 5 is provided with commutator 6, described rotor 3 comprises and turns hub 31 and turn with described the integral type coil windings 32 that hub 31 is connected, described output shaft 1 successively through the bearing of front end housing 4, turn the bearing of hub 31 and rear end cap 5; This drag cup servomotor is owing to having adopted integral type coil windings 32, thus in use, its coil windings 32 can bear can not occur compared with large working strength loose, good stability, can be widely used in intensity high, use workplace frequently.
Further, described integral type coil windings 32 comprises cup coil 321, and described cup coil 321 is fixing by spraying resin bed 322; That is to say, this integral type coil windings 32 is made up of resin bed 322 and cup coil 321, can, in manufacture process, first coil winding be become to cup-shaped, and then on the coil winding, additional resin layer 322 is fixed it,
Further, solidify the rear high molecular weight crosslinked structure coating that forms because epoxy powder resin has, there is good antiseptic property and higher mechanical performance, especially resistance to wear and adhesive force the best.So, as the technical program preferably, described resin bed 322 is epoxy powder resin.
As further improvement project, the outer soft magnetic bodies layer 33 that is equipped with of described cup coil 321.Add that soft magnetic bodies can reduce the leakage field phenomenon of cup coil 321 afterwards, reduce magnetic force loss, increase the power output of motor.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
