Embodiment Construction

[0029] figure 1 Shown is the cross-sectional view of the permanent magnet mounting device of the outer rotor brushless DC motor. The permanent magnet mounting device of the outer rotor brushless DC motor is composed of three parts: the air guide ring assembly, the bracket assembly and the pneumatic arm assembly.

[0030] Among them, the air guide ring assembly is mainly composed of a leading air tube 1, a guiding ball 10, and an air guiding ring 5. The leading air tube 1 is connected to the leading air hole 15 of the guiding ball 10 through a nut, and the inner air guiding hole 21 of the air guiding ring 5 is connected to the main air hole 15 through a nut. The branch air guiding holes 16 of the guiding ball 10 are connected to each other.

[0031] Among them, the bracket assembly is mainly composed of the cantilever fixing column 2, the gas guide ring cantilever 8, the conductive ring fixing frame 3, the positive conductive ring 6 and the negative conductive ring 7, and the c...

Description

[0001] The patent application of the present invention is a divisional application of the invention and creation title "a permanent magnet mounting device for an outer rotor brushless DC motor". The filing date of the original application is September 15, 2015, and the application number is 2015105852055. technical field [0002] The invention relates to hub motor assembly technology, in particular to a permanent magnet mounting device for an outer rotor brushless DC motor. Background technique [0003] Electric vehicles are an important direction for the development of new energy vehicles. Electric vehicles can be divided into hybrid type and pure electric type according to the driving mode. Hybrid vehicles transform the drive system on the basis of traditional fuel vehicles and incorporate a set of electromechanical systems driven by DC power and motors. Pure electric vehicles only provide driving force through motors, which mainly include three parts: power supply, drive ...
