Single-wire control device for brushless direct current motor

Abstract

A single-wire control device for brushless DC (BLDC) motor is disclosed, applicable to the usage between a controller and a pre-drive stage of the BLDC motor, including an encoding modulation unit, a transmission wire, and a demodulation decoding unit; wherein, the encoding modulation unit is connected to the controller to receive a plurality of control signals from the controller, and encodes and modulates the control signals to generate a modulated signal; the transmission wire is connected to the encoding modulation unit for transmitting the modulated signal to the demodulation decoding unit; the demodulation decoding unit is connected to the transmission wire for receiving, demodulate and decoding the modulated signal to generate the original control signal, which is then passed to the pre-driver stage.

Dependencies are inferred from the claim text.
