ABSTRACT:
Lower coils (5b) and upper coils (5a) are inserted to slots (12) of a cylindrical armature core (4). The upper coils are used as crossover lines (102a) at the side of commutator (10) and form commutator segments. The crossover lines are approximately deviated by a pole pitch (yf) at the commutator and inserted to other slots as lower coils. The lower coils are used again as crossover lines and deviated approximately by the pole pitch at the opposite side of the commutator so as to be inserted again to the slots as the lower coils. An insulating resin (11) are forced to push into inner peripheral sides of the armature core, and the crossover lines forming a squirrel cage type shape and extending cylindrically from the core.
