Abstract:
An easy-to-start structure for a D.C. brushless motor, comprising:a base comprising a through-hole having an end, a support section being provided in the end of the through-hole, plural windings and an IC control means being mounted to the base, at least one positioning member being mounted to the base and located within a space defined between said plural windings; and a rotor comprising a shaft and a permanent ring magnet having a north pole and a south pole, each of the south pole and the north pole having a strong magnetic area, said positioning member being arranged to be directly aligned with whichever of the strong magnetic areas is closest to the positioning member when the rotor stops, and the shaft being rotatably held by the support section; said at least one positioning member being made of a material capable of attracting said whichever of the strong magnetic areas is closest and thus retaining one of the strong magnetic areas of the permanent ring magnet in a predetermined angular position proximal to said at least one positioning member when the rotor stops.
