Abstract
The invention discloses a device and a method for eliminating electric potential of a motor core. The device is formed by a stator core; a plastic package body (1) is arranged outside the stator core; a lug boss (2) is arranged at the middle part of one end of the plastic package body (1); a plurality of grooves (3) in a circle are arranged in the periphery of the lug boss (2); an end cover (4) is arranged at the middle part of the lug boss (2); a self-tapping hole (5) which extends to the surface of the stator core is arranged at the side of the lug boss (2); a shielded wire (7) is fixed in the self-tapping hole (5) through a self-tapping screw (6); the other end of the shielded wire (7) is fixed on the end cover (4) through a bolt (8). The method comprises the following steps that one end of the shielded wire is screwed into the self-tapping hole, is in contact with the surface of the stator core, and is embedded into the groove through the middle section of the shielded wire, and the other end of the shielded wire is fixed on the end cover through the bolt. According to the device and the method, the electric potential of the motor core can be eliminated to prevent a bearing from electric corrosion, so that the service life of the bearing is prolonged.
Description
Technical field
the present invention relates to a kind of plastic packaging motor field, particularly a kind of elimination electric machine iron core electromotive force device and method.
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.
Summary of the invention
the object of the invention is to, provide a kind of and eliminate electric machine iron core electromotive force device and method.The present invention can eliminate electric machine iron core electromotive force, prevents bearing by galvanic corrosion, thus extends the useful life of bearing.
technical scheme of the present invention: 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.
eliminate the method for electric machine iron core electromotive force device, by self-tapping screw one end of shielding conductor is screwed into self tapping hole and with stator core surface contact, the interlude through shielding conductor is embedded in groove, and the other end of shielding conductor is fixed by screws on end cap.
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 present invention, 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 present invention, 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 invention.
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 present invention is further illustrated, but not as the foundation limited the present invention.
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.
according to the method for described elimination electric machine iron core electromotive force device, by self-tapping screw one end of shielding conductor is screwed into self tapping hole and with stator core surface contact, the interlude through shielding conductor is embedded in groove, and the other end of shielding conductor is fixed by screws on end cap.
one end of shielding conductor to be fixed in self tapping hole by self-tapping screw and to contact with stator core by the present invention, 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 present invention, rationally can not only hide, not affect the appearance, and can not also hinder normal operation and the structure of motor.
