Document Type and Number:
WIPO Patent Application WO/2023/193832
Kind Code:
A2
Abstract:
The present invention belongs to the technical field of motors, and disclosed are a non-polarized power supply circuit for a direct-current brushless motor and a control method. The circuit comprises a microcontroller chip, a polarity determination circuit, a pre-drive and power switch circuit, a voltage sampling circuit, and a current sampling circuit; the microcontroller chip is provided with a plurality of leads, each described circuit is connected to a different lead, and a direct-current brushless motor is connected to the pre-drive and power switch circuit. By utilizing the non-polarized power supply circuit, direct-current brushless motors can replace traditional brushed motors; the present invention has the advantages of being highly efficient and producing little noise; the present invention has no additional complexity in wiring compared to traditional direct-current brushed motors, direct replacement can be achieved, and a design scheme is simple and easy to implement.
