Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Such as figure 1 As shown, a bidirectional non-reluctance DC motor includes a rotor 1, a stator 2 and a motor shaft 3. The inner wall of the rotor 1 is provided with a permanent magnet 9, and the stator 2 is arranged in the rotor 1.

[0021] Such as figure 2 , 3 As shown, the motor shaft 3 is connected to the stator 2 through the one-way clutch 4. The stator 2 is provided with a carbon brush, and the motor shaft 3 is provided with a slip ring matchin...

Abstract

The invention relates to the technical field of motor, in particular to a bidirectional DC motor without reluctance. The motor includes a rotor, a stator, and a motor shaft. Permanent magnets are arranged on the inner wall of the rotor. The stator is arranged in the rotor. The motor shaft is connected with the stator through a one-way bearing. The stator is provided with a brush assembly bar. The motor shaft is provided with a slip ring matching the brush assembly bar. The stator is provided with a locking device through which the stator and the motor shaft can be fixed. When the bidirectional DC motor without reluctance is used in an electric vehicle or other tools, no matter whether the electric vehicle or the like drives forwards or backwards, no reluctance will be produced between the stator and the rotor of the motor, and thus the driving of the electric vehicle or the like is facilitated. Moreover, the device is simple, time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a bidirectional non-reluctance DC motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its basic structure includes a stator and a rotor. The stator is composed of spokes arranged in a circular shape and ring-shaped silicon steel sheets fixed to the outer ends of the spokes. The rotor is composed of steel walls opposite to the ring-shaped silicon steel sheets and steel The wall is composed of circular and tightly arranged rectangular magnetic poles, and the spokes are directly fixed with the axles of electric vehicles and the like. [0003] In the prior art, patent 201120198110.5 discloses a non-reluctance motor for electric vehicles, which includes a rotor and permanent magnets fixed on the inner wall of the rotor in a ring-shaped and tightly arranged manner. Ther...
