Abstract
The utility model discloses a kind of elimination electric machine iron core electromotive force device, form and comprise stator core, plastic-sealed body (1) is provided with outside stator core, boss (2) is provided with in the middle part of one end of plastic-sealed body (1), the periphery of boss (2) is provided with and somely encloses conglobate groove (3), and the middle part of boss (2) is provided with end cap (4); Described boss (2) is other is provided with the self tapping hole (5) extending to stator core surface, be fixed with shielding conductor (7) through self-tapping screw (6) in self tapping hole (5), the other end of shielding conductor (7) is fixed on end cap (4) through screw (8).The utility model can eliminate electric machine iron core electromotive force, prevents bearing by galvanic corrosion, thus extends the useful life of bearing.
Description
Technical field
The utility model relates to a kind of plastic packaging motor field, particularly a kind of elimination electric machine iron core electromotive force device.
Background technology
Plastic packaging motor adopts plastic package technology that the stator core of motor, winding etc. are carried out overall package with engineering plastics, can cancel traditional motor stator insulated treatment process and the metal chassis of common electric machine.Plastic packaging motor is made up of plastic packaging stator, axle, rotor, bearing, end cap and thermal protector, lead-out wire, socket etc.During due to motor rotation, armature spindle produces magnetic field, and Hui Zhou two ends, magnetic field form electromotive force, and this electromotive force can corrode bearing, has a significant impact the life-span of bearing.
Utility model content
The purpose of this utility model is, provides a kind of and eliminates electric machine iron core electromotive force device.The utility model can eliminate electric machine iron core electromotive force, prevents bearing by galvanic corrosion, thus extends the useful life of bearing.
The technical solution of the utility model: a kind of elimination electric machine iron core electromotive force device, it is characterized in that: comprise stator core, outside stator core, be provided with plastic-sealed body, in the middle part of one end of plastic-sealed body, be provided with boss, the periphery of boss is provided with and somely encloses conglobate groove, and the middle part of boss is provided with end cap; Described boss is other is provided with the self tapping hole extending to stator core surface, and self tapping is fixed with shielding conductor through self-tapping screw in hole, and the other end of shielding conductor is fixed on end cap through screw.
In aforesaid elimination electric machine iron core electromotive force device, described shielding conductor is arranged in groove.
Compared with prior art, one end of shielding conductor to be fixed in self tapping hole by self-tapping screw and to contact with stator core by the utility model, and the shielding conductor other end is fixed on end cap through screw, thus by conducting between stator core and end cap, when motor rotation, armature spindle produces magnetic field, and Hui Zhou two ends, magnetic field form electromotive force, and energy of position is delivered on end cap, thus elimination electromotive force, effectively prevent motor bearings galvanic corrosion phenomenon, thus extend the useful life of bearing, the use safety of motor can also be improved.Shielding conductor is also arranged in the groove of end cap by the utility model, rationally can not only hide, not affect the appearance, and can not also hinder normal operation and the structure of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-plastic-sealed body, 2-boss, 3-groove, 4-end cap, 5-self tapping hole, 6-self-tapping screw, 7-shielding conductor, 8-screw.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.A kind of elimination electric machine iron core electromotive force device, forms as shown in Figure 1, it is characterized in that: comprise stator core, plastic-sealed body 1 is provided with outside stator core, be provided with boss 2 in the middle part of one end of plastic-sealed body 1, the periphery of boss 2 is provided with and somely encloses conglobate groove 3, and the middle part of boss 2 is provided with end cap 4; Described boss 2 is other is provided with the self tapping hole 5 extending to stator core surface, and be fixed with shielding conductor 7 through self-tapping screw 6 in self tapping hole 5, the other end of shielding conductor 7 is fixed on end cap 4 through screw 8.Described shielding conductor 7 one end to be screwed in self tapping hole by self-tapping screw 6 and with stator core surface contact.
Reasonable, described shielding conductor 7 is arranged in groove 3, can hide obviously, ensure attractive in appearance.
One end of shielding conductor to be fixed in self tapping hole by self-tapping screw and to contact with stator core by the utility model, the shielding conductor other end is fixed on end cap through screw, thus by conducting between stator core and end cap, when motor rotation, armature spindle produces magnetic field, Hui Zhou two ends, magnetic field form electromotive force, energy of position is delivered on end cap, thus eliminates electromotive force, effectively prevents motor bearings galvanic corrosion phenomenon, thus extend the useful life of bearing, the use safety of motor can also be improved.Shielding conductor is also arranged in the groove of end cap by the utility model, rationally can not only hide, not affect the appearance, and can not also hinder normal operation and the structure of motor.
Claims (2)
1. eliminate electric machine iron core electromotive force device for one kind, it is characterized in that: comprise stator core, plastic-sealed body (1) is provided with outside stator core, boss (2) is provided with in the middle part of one end of plastic-sealed body (1), the periphery of boss (2) is provided with and somely encloses conglobate groove (3), and the middle part of boss (2) is provided with end cap (4); Described boss (2) is other is provided with the self tapping hole (5) extending to stator core surface, be fixed with shielding conductor (7) through self-tapping screw (6) in self tapping hole (5), the other end of shielding conductor (7) is fixed on end cap (4) through screw (8).
