Direct current brushless motor includes permanent magnet ring and coil set, which are arranged around periphery of base, for producing mutually repulsive forces so as to drive rotor

摘要

A film printed circuit (2) includes opposing coil sets (21) distributed on a base (1) having a receiving chamber (11). A rotor has a shaft pivoted on the shaft hole (13) of the base, and a permanent magnet ring (32). The ring and the coil sets are arranged around the periphery of the base, for producing mutually repulsive forces so as to drive the rotor.
