Abstract
A stator for a direct current motor belongs to the technical field of motor manufacturing and mainly comprises a winding (8), a stator core (7) with a permanent magnet (5) and the like, wherein the direction of a permanent magnetic field of the permanent magnet (15) is vertical to the direction of an excitation magnetic field of the stator core (7). The excitation and permanent magnet composite stator formed by the method enables the structural design of the stator of the direct current motor to be more reasonable and scientific, and enables the change of the current reversing angle to be matched and adapted with the magnetic field of the excitation and permanent magnet composite stator after the stator and the rotor form the direct current motor, thereby effectively enhancing and changing the distribution condition of the magnetic density of the magnetic field, overcoming the low torque area, changing the output characteristic of the motor, effectively reducing the additional resistance load and having obvious electricity-saving effect.
Description
Technical field
The utility model relates to a kind of direct current machine stator, belongs to the manufacturing technology field of motor.
Background technology
Have widely used middle low power direct current machine on electric automobile, light industrial goods, household electrical appliance now, or the carbon brush reversing motor of also sharp or series excitation or compounding, its stator is all for being made of around magnet exciting coil a pair of stator core, it is different so causing the rotor coil moment of torsion that different angle position produced in magnetic field, is alternation.With single turn rectangle plane coil is example, when coil plane is in the upright position, magnetic field, and the moment that coil will not rotate, coil is to rely on inertia to turn over.Above-mentioned situation must cause the unsmooth of rotating speed, after loading, will produce the operational shock of motor, has so increased harmful additional dynamic load, makes idle work more, thereby causes the decline of electric efficiency.This also be adopt direct current machine to be used as power at present its efficient of electric automobile of device is low, power consumption big, the short problem place of continuous journey.
Summary of the invention
It is a kind of reasonable in design that the purpose of this utility model is to provide, and can effectively improve running efficiency, the tangible direct current machine stator of power savings.
The utility model is a kind of direct current machine stator, comprises stator core and winding, it is characterized in that the both sides of stator core also are provided with a pair of permanent magnet, and the permanent magnetic field direction of permanent magnet and the excitation field direction of stator core are perpendicular.
The utility model is according to direct current machine magnetic field principle features, the compound stator of excitation, permanent magnetism that employing is made of stator core and a pair of permanent magnet, make the more reasonable structural design science of DC motor stator, behind rotor formation direct current machine, make the adaptation that is complementary of the variation of electric current commutation angle and excitation, the compound stator field of permanent magnetism, thereby effectively strengthen and changed the close distribution situation of magnetic field magnetic, overcome low torque district, changed the motor output characteristic, effectively reduced additional drag load, power savings is obvious.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
Embodiment
The utility model is with stator core 7 formations such as grade of permanent magnet 5 mainly by winding 8.
The compound stator 6 of the excitation of said structure, permanent magnetism with by rotor core 10, the coil 1 of belt current commutator segment 2, place a pair of commutation carbon brush 3 on the electric current commutator segment 2,3 ' and a pair of carbon brush 4,4 ' of crossing wait formation rotor 9 supporting, when on electrocar, using, under the constant situation of vehicle condition, road conditions, load, storage battery capacity, speed per hour can be brought up to now average 70KM, the highest 100KM by original average 30KM, the highest 40KM, and mileages of continuation is brought up to existing 20KM by former 60KM.
Claims (1)
1, a kind of direct current machine stator, comprise stator core (7) and winding (8), the both sides that it is characterized in that stator core (7) also are provided with a pair of permanent magnet (15), and the excitation field direction of the permanent magnetic field direction of permanent magnet (15) and stator core (7) is perpendicular.
