Description

A kind of brush motor

Technical field

This utility model relates to a kind of drive motor, refers in particular to a kind of brush motor.

Background technology

Brush motor is to include converting electric energy to mechanical energy (motor) or converting mechanical energy into the electric rotating machine of electric energy (electromotor) of brushgear.Brush motor is the basis of all motors, it has, and startup is fast, braking in time, can the features such as smoothly speed governing on a large scale, control circuit be relatively easy.

Brush motor is made up of stator and rotor two large divisions, stator has magnetic pole (winding type or magneto), rotor has winding, after energising, rotor is also formed magnetic field, an angle is had between stator and the magnetic pole of rotor, under the attracting each other in rotor magnetic field, make motor rotate, change the position of brush, just can change the direction of rotor magnetic pole angle, thus changing the direction of rotation of motor, during the commutation of high speed brush motor, diverter is continually changing, commutation effect can worse and worse, and service life is short.

Utility model content

The purpose of this utility model be to provide a kind of rational in infrastructure, commutation better effects if a kind of brush motor.

nullThis utility model solves its technical problem and be the technical scheme is that a kind of brush motor of the present utility model，Including stator and rotor，Rotor includes rotating shaft、Winding、Iron core and diverter，Its shaft is sequentially provided with outfan、Magnet installation end、Transducer positive stop end、Spline and fastening end，Described iron core is fixed in rotating shaft，Winding is wound in around iron core，Iron core and be wound in the winding on iron core and diverter is axially arranged side by side along rotating shaft，Stator includes Magnet、Carbon brush、Fixed gear and shell，The quantity of fixed gear is two，Fixed gear is assemblied in the two ends of Magnet，Play fixing and position-limiting action，The quantity of described diverter is two，One diverter electrically connects with winding，Another diverter electrically connects with iron core，Described Magnet is radially provided with several breach and axis hole，Wherein breach array is arranged on around Magnet，It is uniformly distributed，Described carbon brush coordinates assembling and is fixed on stator end cap place with breach；

Further, wherein the outside dimension of carbon brush and the inside dimension of breach are matched in clearance size；

Further, wherein the quantity of carbon brush and the quantity of breach are identical；

Further, wherein winding is interior outer double-layer structure.

This utility model has the advantage that and has the benefit effect that this motor structure with brush is reasonable, adopts the frame for movement of two diverters to realize two grades of commutations, thus the effect that realizes better commutating, wearability is good, and repair rate is low.
