Description
Technical field
The utility model relates to a kind of motor, specifically a kind of improved electric motor.
Background technology
Motor is applied very extensive in hyundai electronics, electrical equipment and industrial equipment.Existing motor limit because of its structure and working principle, generally all carbon brush can be used, carbon brush is commutator for motor or slip ring, as deriving the sliding contact body importing electric current, its conduction, heat conduction and greasy property well, and have the instinct of certain mechanical strength and suppression commutation spark, and carbon brush is the important composition parts of motor.
In existing motor, carbon brush is generally arranged in the carbon brush seat in motor, and rearward end and the fixing connecting card on carbon brush seat is conflicted and coordinated, and utilizes this connecting card to realize tail end stop bit and the conduction of carbon brush.There is certain drawback in this kind of structure, specifically, this kind of structure needs to use connecting card, and connecting card also needs to fix with carbon brush seat to coordinate, the outer wire connected also needs to carry out soldered with connecting card simultaneously, this just makes the integral production cost of motor higher, and step is more, is unfavorable for the industrialized mass production of motor.
Utility model content
The utility model is to overcome the deficiency existing for existing motor, provides a kind of improved electric motor not needing to use connecting card.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of improved electric motor, comprises fore-stock, after-poppet, main shaft, rotor windings, rotor core, stator winding, stator core, commutator, carbon brush seat, carbon brush.
Rotor core is set in the middle part of main shaft, and rotor core is provided with some rotor windings;
Rotor core inserts in stator core, and contraposition coordinates with it;
Stator core is provided with some stator winding;
Main shaft tail is arranged with commutator;
Fore-stock is provided with a bearing by retainer, and front-end of spindle inserts in this bearing, coordinates with it;
After-poppet is provided with a bearing by retainer, and main shaft tail end inserts in this bearing, coordinates with it;
Fore-stock, stator core, after-poppet are integrated by some connected nail fixeds;
On after-poppet, symmetry is installed on two carbon brush seats, carbon brush seat offers the mounting groove coordinated with carbon brush;
Carbon brush seat offers the two symmetrical connecting holes be connected with mounting groove;
Rigid connection wire is inserted with in two connecting holes;
Carbon brush is inserted in mounting groove;
The power spring that carbon brush comprises charcoal block and is connected with charcoal block, conflict with commutator and coordinate in charcoal block front end, power spring tail end is conflicted with rigid connection wire and coordinated, and realizes stop bit and the conduction of carbon brush.
The utility model structure is simple, reasonable in design, need not produce, assemble, soldered connecting card, saves a large amount of production cost, effectively improves integral production efficiency, and not easily causes machine operation unstable because of the rosin joint connected between wire and connecting card.
