Problems solved by technology

In this way, no matter where the elongated positioning piece is located on the base, as long as the positioning piece passes through the rotation axis of the hub, the positioning piece will touch the metal shaft tube, resulting in magnetic flux leakage Phenomenon, and will produce structural interference with the shaft tube, so the existing motor of this type cannot apply the technology of the above-mentioned easy-to-start motor 9

[0068] Please refer to figure 2 , which is the first embodiment of the easy-to-start thin motor of the present invention, the easy-to-start thin motor generally includes a base 1, and a stator 2, a rotor 3 and a magnetic attraction set on the base 1 Ring 4.

[0069] Please refer to figure 2 , image 3 , the base 1 has an opposite inner surface 1a and an outer surface 1b, the inner surface 1a of the base 1 is protruded with a shaft tube 11; in this embodiment, the shaft tube 11 is integrated with the inner surface 1a Therefore, the base 1 can be integrally injection-molded with plastic material to improve the manufacturing convenience of the base 1 . In addition, the base 1 can also be provided with an anti-rotation part 12 to prevent the magnetic ring 4 from rotating on the base 1, so as to improve the positioning effect of the magnetic ring 4; the anti-rotation part 12 can For example, two bumps on the inner surface 1a, or other equivalent structures, the present invent...

Abstract

A thin-type motor being easy to start is used for solving the problems that an existing thin-type motor being easy to start is poor in universality. The motor comprises a base which is provided with ashaft tube; a stator which is combined with the base; a rotor which is rotatably assembled on the shaft tube and is provided with a magnetic assembly; and a magnetic attraction ring which is providedwith an annular body and two positioning parts, the two positioning parts being oppositely connected to the annular body in the radial direction, the annular body being arranged on the periphery of the shaft tube in a sleeving mode, the annular body and the magnetic assembly being arranged in an axial staggered mode, and the two positioning parts being axially opposite to the magnetic assembly respectively.

Description

technical field [0001] The invention relates to a motor, in particular to an easy-to-start thin motor. Background technique [0002] Generally speaking, the existing motor generally includes a base, a rotor and a stator; the base is provided with a shaft tube for the rotor to be rotatably combined, and the stator is combined with the base. In this way, after the stator is energized to generate a magnetic field, it can be used to drive the rotor to rotate. However, when the existing motors are used in practice, there are still problems such as difficulty in starting or dead spots in starting. For this reason, the current common motors are equipped with related structures that are "easy to start". [0003] Please refer to figure 1 , is one of the existing easy-to-start motors 9 , which has a base 91 , a rotor 92 and a stator 93 . The base 91 has an inner surface 911 and an outer surface 912 opposite to each other, and the base 91 has a shaft tube 913 on the inner surface 91...
