Embodiment Construction

[0028] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0029] Such as figure 1 , image 3 with Figure 8 As shown, a hub integrated DC brushless motor according to the present invention includes a motor housing 10 , a motor shaft 1 , a motor end cover 4 , a stator 9 and a magnetic steel ring 7 . The motor shaft 1 is installed through the center of the motor housing 10, that is, the middle part of the motor housing 10. The motor end cover 4 is fixedly installed with the motor housing 10 through the bearing 2, forming a motor housing through which the motor shaft 1 passes. The body 10 and the motor end cover 4 are a closed combination, so that air cannot enter the inside of the motor, which is suitable for use in rain, mud and dust environments, and improves the reliability of the equipm...

Abstract

The invention relates to an integrated direct-current brushless motor of a wheel hub. Compared with the prior art, the integrated direct-current brushless motor of the wheel hub overcomes the defect that an integrated direct-current brushless motor of a wheel hub cannot operate at a high speed. The integrated direct-current brushless motor comprises a motor shell, a motor shaft, a motor end cover, a stator and a magnetic steel ring. The motor shaft is installed in the center of the motor shell in a penetrating mode, the motor end cover and the motor shell are fixedly installed through a bearing, the inner circle of the magnetic steel ring is provided with magnetic steel in an adhering mode and is installed in the motor shell through the motor shaft in a penetrating mode, the stator is embedded on the magnetic steel ring and is installed through the motor shaft in a penetrating mode, wire windings penetrate through wire embedded troughs formed by clamping jaws of the stator and are connected outside through shaft holes in the motor shaft, and the wire embedded troughs are in asymmetric elliptic structures with wide outsides and narrow insides. According to the motor, high-power and low-speed large torque is achieved, starting currents are low, and the motor shaft is small in axial dimension and easy to assemble.

Description

[0001] technical field [0002] The invention relates to the technical field of DC brushless motors, in particular to a hub-integrated DC brushless motor. [0003] Background technique [0004] At present, the power unit of the known motorcycle is composed of a gasoline engine and a gearbox, and the characteristics of its fuel oil have caused emission pollution and high running costs. In order to solve these disadvantages, the idea of ​​electric-driven motorcycles has emerged. According to the limitations of electric drive due to factors such as battery charging and cruising range, the transmission efficiency of the entire power system is required to be high. Therefore, the best power device for electric motorcycles should be the hub. It is integrated with the motor, that is, the speed-regulating motor is directly driven to reduce the mechanical loss in the transmission process. [0005] The hub motors of electric motorcycles on the market generally have low power, small t...
