MANUFACTURING METHOD FOR RESIN MOLD ARMATURE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a resin mold armature with high performance, simple constitution and high reliability. SOLUTION: After a single coil group 4 is put in a mold, a sealing resin 5 is injection-molded holding a peripheral portion of the single coil group 4 positioned at a periphery of a rib 7 for correcting an unbalanced rotation in a shape of a concentric ring to a commutator in the mold.
