STATOR STRUCTURE FOR OUTER ROTOR TYPE MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a stator structure for an outer rotor type motor enabling wiring in a narrow space between stator units with a good workability without deteriorating the lamination factor of a coil as well as the reliability of insulation between a coil and a stator yoke.

SOLUTION: A stator structure for an outer rotor type motor which comprises: an output axis; a stator 4 in which a plurality of stator units are concentrically laminated, while the stator unit is composed of a coil 6 wound with magnet wire and sandwiched by stator yokes having magnetic pole teeth 7c and 7d arranged in an interdigital manner; a rotator 1 supported so as to freely rotate on the output axis; and a terminal portion of a driving circuit which is a terminal of a driving circuit to drive the motor. Coil leads 8 for wiring from the coils 6 to the terminal portion of the driving circuit pass through the spaces between magnetic pole teeth 7c and 7d of the stator units 4a-4d and are wired along the outer surface of the stator 4.
