Wheel hub motor

Abstract

The invention relates to a wheel hub motor, which comprises a motor main body, a carrying disc and a magnetic ring, wherein the motor main body comprises a rotor mandrel, and the rotor mandrel comprises a joint end part; the carrying disc comprises a disc body which is fixedly connected onto the joint end part and a circumambient wall which extends outwards from the outer periphery of the disc body in the axial direction; and the magnetic ring is fixedly connected onto the carrying disc and is pushed against the disc body and the inner wall surface of the circumambient wall, and by adopting the design way that the magnetic ring is fixed on the carrying disc and the carrying disc is fixedly connected onto the joint end part of the rotor mandrel, the situation that the carrying disc and the magnetic ring have axial displacement along a shaft rod of the rotor mandrel can be avoided.

Description

technical field [0001] The invention relates to a motor, in particular to a DC brushless hub motor arranged in a wheel frame. Background technique [0002] In the improvement of the structure of the brushless DC motor disclosed in Taiwan Patent No. M358466 (application number 97220505), the electromagnet is sleeved on the spindle of the motor body and rotates with the spindle. If the electromagnet When the stability of the joint with the mandrel is not good, the electromagnet is prone to displacement along the axial direction of the mandrel during the rotation of the mandrel, thereby affecting the sensing result of the Hall sensing element. [0003] It can be seen that the above-mentioned existing DC brushless motor obviously still has inconveniences and defects in structure and use, and needs to be further improved urgently. In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been d...

Problems solved by technology

[0002] In the improvement of the structure of the brushless DC motor disclosed in Taiwan Patent No. M358466 (application number 97220505), the electromagnet is sleeved on the spindle of the motor body and rotates with the spindle. If the electromagnet When the stability of the joint with the mandrel is not good, the electromagnet is prone to displacement along the axial direction of the mandrel during the rotation of the mandrel, which in turn affects the sensing results of the Hall sensing element

[0003] This shows that the above-mentioned existing brushless DC motor obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
