Title:
ROTARY RECTIFIER SUITABLE FOR HIGH SPEED AND LARGE CURRENT
Document Type and Number:
WIPO Patent Application WO/2022/257914
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of rotary rectification of electric motors, aims to solve the problem that existing rotary rectifiers cannot meet the requirements of safe operation under high-speed and large-current conditions, and specifically relates to a rotary rectifier suitable for high-speed and heavy-current conditions. The rotary rectifier comprises a housing, a rectifier element, a copper busbar, and an insulating component, wherein the copper busbar comprises a phase-A copper bar, a phase-B copper bar, a phase-C copper bar, an excitation positive copper bar, and an excitation negative copper bar; the insulating component comprises a phase-A copper bar insulator, a phase-B copper bar insulator, a phase-C copper bar insulator, an excitation positive copper bar insulator, and an excitation negative copper bar insulator; and the rectifier element comprises a phase-A diode, which is arranged between the phase-A copper bar and the excitation negative copper bar, a phase-B diode, which is arranged between the phase-B copper bar and the excitation positive copper bar, and a phase-C diode, which is arranged between the excitation positive copper bar and the phase-C copper bar. The rotary rectifier of the present invention has high integration and a compact structure, effectively ensuring the safe operation thereof.
