Abstract:
A direct current brushless motor, comprising:a base, having a single slot extending around a periphery of the base and a receiving chamber whose one end is formed with a shaft hole; a film printed circuit, having at least two coil sets, a Hall sensing drive member set, and a connecting end for connecting on with a power supply, the film printed circuit being positioned in the signal slot so as to extend around a periphery of the base, and each of the coil sets of the film printed circuit being oppositely distributed on the periphery of the base in an equally angular manner with the receiving chamber serving as a center; and a rotor, having a rotation shaft and a permanent magnet ring, the rotation shaft pivoted on the shaft hole of the base, the permanent magnet ring and each of the coil sets around the periphery of the base directly producing mutually repulsive forces, so that the rotor is driven to rotate successively.
