Abstract
The utility model discloses a DC motor, which comprises a shaft and an electromagnet installed on the shaft; two permanent magnets are symmetrically installed on two sides of the electromagnet; and the permanent magnets are circular ring shaped. The electromagnet is electrified to drive the permanent magnet to move and further drive the motor to work. The DC motor depending to the magnetic attraction principle has simple structure and high efficiency.
Description
Technical field
The utility model relates to a kind of DC motor.
Background technology
At present, motor mainly is to adopt alternating current, utilizes alternating magnetic field to make motor work.The efficient of some motor is comparatively low.
The utility model content
The purpose of this utility model is to provide a kind of DC motor, and is simple in structure, efficient is higher.
The utility model provides a kind of DC motor, comprises axle and the electromagnet that is installed on the axle, in the both sides of described electromagnet, is symmetrically installed with two permanent magnets, and described two permanent magnets are annular.
Adopt DC motor of the present utility model, during the electromagnet energising, allow permanent magnet move, make and realize motor work utilizing magnetic to inhale the DC motor of principle mutually, simple in structure, efficient is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model DC motor.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model embodiment is done further and to be elaborated.
See also Fig. 1, a kind of DC motor comprises axle 11 and the electromagnet 12 that is installed on the axle, and in the both sides of electromagnet, being symmetrically installed with 13,14, two permanent magnets of two permanent magnets is annular.
Adopt the DC motor of present embodiment, during the electromagnet energising, allow permanent magnet motion, permanent magnet move to farthest/during most proximal end, deenergization because electromagnet is made of iron, thereby makes that permanent magnet can be under the effect of magnetic force, counter motion.By utilizing magnetic to inhale principle work mutually between electromagnet and the permanent magnet, realize direct current supply, simple in structure, efficient is higher.
The above only is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (1)
1. a DC motor comprises axle and the electromagnet that is installed on the axle, it is characterized in that in the both sides of described electromagnet, be symmetrically installed with two permanent magnets, described two permanent magnets are annular.
