STATOR OF MOLDED MOTOR, MOTOR AND DRIVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a small and lightweight molded motor exhibiting high water resistant performance. SOLUTION: The stator of a motor covered with mold resin 8 comprises a tubular yoke section, a plurality of teeth projecting radially at a constant interval, and a stator core 1 consisting of slots formed by the teeth and the yoke wherein a boss 3 is fastened to the yoke and a winding 2 is applied to the teeth through an insulator. The insulator of the teeth, the stator core 1 and the 3 boundary surfaces of the boss 3 are substantially matched and the mold resin 8 is injected at least to the 3 boundary surfaces in order to enhance water resistance on the interface thus enhancing reliability of the winding part with regard to water intrusion.
