Easy-to-start structure of a DC brushless motor |
摘要 |
An easy-to-start structure for a D.C. brushless motor comprises a base including a through-hole. Plural windings and an IC control member are mounted to the base. At least one magnetically attractive positioning member is mounted to the base and located between two windings that are adjacent to each other. A rotor comprises a shaft rotatably held by a support section in the through-hole and a permanent ring magnet mounted to the shaft, the permanent ring magnet having north and south poles, each of the south pole and the north pole having a strong magnetic area. The positioning member attracts and thus retains one of the strong magnetic areas of the permanent ring magnet in a position proximal to the positioning member when the rotor stops. Thus, the rotor rests in a pre-determined position not located in a dead corner for restarting.
