Abstract

PURPOSE: To make the manufacturing cost lower by forming the end insulator with plastic sheet bendable depending on the winding of armature coil.
CONSTITUTION: Plastic sheet is stamped out and bent by the press to form an end insulator 8 which has the end 8a similar to the end face of the armature core 3 and has the fin 8b that makes an obtuse angle θ with the end 8a. The armature coil 1 is installed on the core 3 so that the fin of end insulator is placed in contact with the end face in the axial direction of armature core. Thus the end insylator can be manufactured at a lower cost since it is made of plastic sheet bendable depending on the winding of the armature coil, its thickness can also be made extremely thin to make the number of turns of the coil greater.
