Abstract
A brushless motor device controlled by a carrier of DC positive and negative power wires comprises a controller. The controller outputs a positive DC wire for outputting a positive DC voltage and a negative DC wire for outputting a negative DC voltage. The positive and negative DC voltages include a carrier signal. The controller is connected to a driver which is applied to receive the carrier signal and control a rotating mode of a brushless DC motor according to the carrier signal. Therefore, the carrier signal allows the driver and the controller to be connected by the positive and negative DC wires and attains the object of transmitting the signal, thereby reducing the material of the signal wire and the manufacture cost.
