Abstract
The utility model provides a high power N-S type direct current permanent magnet motor which comprises a stator, a rotor and a carbon brush. The stator comprises a casing, permanent magnets and an end cover. The rotor comprises a disk, a coil and a shaft. The stator is formed by connecting the casing and the end cover. The casing and the end cover are respectively provided with a circular permanent magnet. N-S magnetic poles of the two permanent magnets are corresponding. The rotor is arranged between the two permanent magnets. The rotor is formed by connecting the shaft and the plastic disk. The disk is wound with the coil. The shaft is arranged in an end cover shaft hole. The end cover is provided with the carbon brush which electrically contacts the coil on the rotor. The N-S type direct current permanent magnet motor is applied to an electric bicycle and has the advantages of high power, light weight and low cost.
Description
Technical field
The utility model relates to a kind of motor of electric bicycle, and the big N-S type direct current permanent magnet motor of power output is especially arranged.
Background technology
The present no iron core rotor direct current permanent magnet motor of existing electric bicycle, it is made up of shell, permanent magnet, rotor, carbon brush, end cap, and that this motor has is in light weight, cost is low, but disposes because permanent magnet has only on one side, has the little deficiency of power output.
Summary of the invention
In order to overcome existing no iron core rotor direct current permanent magnet motor, there is the little deficiency of power output, the purpose of this utility model provides a kind of power output big N-S type direct current permanent magnet motor.
The utility model technical scheme that adopts of dealing with problems is: it comprises stator, rotor, carbon brush, stator comprises shell, permanent magnet, end cap, rotor comprises disk, coil, axle, stator is connected to form by shell and end cap, respectively be provided with a round ring magnet on shell and the end cap, two permanent magnet N-S magnetic poles are corresponding, in the middle of two permanent magnets, be provided with a rotor, rotor is connected to form by axle and plastic disc, be wound with coil on the disk, axle is contained in the end cap axis hole, is provided with at end cap that coil electrically contacts on carbon brush and the rotor.This motor is former existing identical with the no iron core rotor direct current permanent magnet motor of tradition, has only increased a permanent magnet, and the N-S magnetic pole of two permanent magnets should be able to increase magnetic flux relatively, shortens magnetic circuit, thereby reach the utility model the big purpose of power output is arranged.
The beneficial effects of the utility model are, have power output big, in addition in light weight, cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is the sectional arrangement drawing of the utility model embodiment.
Among the figure 1, stator 1-1, shell 1-2, permanent magnet 1-3, end cap 2, rotor 2-1, coil 2-2, disk 2-3, axle 3, carbon brush
Embodiment
In the embodiment shown in the figure, stator 1 is connected to form by shell 1-1 and end cap 1-3, each bonding many magnetic poles of annular permanent magnet 1-2 on the inner face of shell 1-1 and end cap 1-3, the N-S magnetic pole of two permanent magnet 1-2 is corresponding, in the middle of two permanent magnet 1-3, be provided with a rotor 2, rotor 2 is connected to form by axle 2-3 and plastic disc 2-2, and disk 2-2 is provided with coil 2-1, and axle 2-3 is contained in the end cap 1-3 axis hole.Carbon brush 3 is contained in end cap 1-3 upward and the coil 2-1 on the rotor 2 electrically contacts, and plays the transformation that coil 2-1 direct current advances the positive and negative electrode of electricity, rotor 2 and stator 1 magnetic field is interacted produce torque.This motor adopts the N-S magnetic pole of two permanent magnet 1-3 corresponding, not only can increase magnetic flux, can also shorten magnetic loop, and power output is just big.
