Problems solved by technology
[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a ring-shaped capacitor suitable for hub motors and its manufacturing method. By designing the structure of the capacitor as a ring, it solves the problem of adapting ordinary square capacitors in the application of hub motors. Cylindrical controllers cause large space waste and low power density. The ring-shaped composite busbar ensures the dimensional accuracy of the product and reduces the self-inductance of the capacitor. The overall design is compact and has good machinability

The invention discloses an annular capacitor applicable to wheel hub motors and a manufacturing method thereof. The annular capacitor includes an annular plastic shell, a plurality of capacitor cores, two bus bar components used as positive and negative poles, and a potting material body. The capacitor cores are annularly distributed in the plastic shell, and the winding axis of each capacitor core is along the axis direction of the ring. The two ring-shaped bus bar components match each other in the plastic shell in a mutually insulated manner, and surround the capacitor cores. Each of the two bus bar components is connected with one end of each capacitor core. The two bus bar components are respectively provided with lead-out ends extending out of the plastic shell. The potting material body fills the space formed by the capacitor cores, the two bus bar components and the plastic shell. The problem that waste of a lot of space and low power density are caused when a common square capacitor is matched with a cylindrical controller in the application of a wheel hub motor is solved.
Description
technical field [0001] The invention relates to the technical field of film capacitors, in particular to an annular capacitor suitable for in-wheel motors and a manufacturing method thereof. Background technique [0002] New energy vehicles have now become a forward-looking field in the automotive industry, and the driving technology of new energy vehicles is quite different from traditional internal combustion engine vehicles, and one type of driving technology has great development prospects, which is in-wheel motor technology. [0003] In-wheel motor technology, also known as in-wheel motor technology, is characterized by the integration of power, transmission and braking devices into the wheel hub, thus greatly simplifying the mechanical parts of electric vehicles. The in-wheel motor has the characteristics of independent drive of a single wheel, so whether it is front-wheel drive, rear-drive or four-wheel drive, it can be realized relatively easily. At the same time, th...
