ABSTRACT:
A stator for a rotary machine is produced by a method which includes the steps of: mounting terminal pins to one end of a main core unit which has teeth protruding from its outside; winding the beginning part of a coil wire around one of the terminal pins, and then winding the coil wire around a plurality of adjoining teeth to form a coil and repeating the formation of a coil until a predetermined number of coils are obtained on the outside of the main core unit, and thereafter winding the ending part of the coil wire around one of the other terminal pins; fitting a ring unit on the outside of the main core unit while these units are respectively kept in appropriate shapes by adjusting members; and inserting wedge members between the outside of the coils and protrusions formed on the outer ends of the teeth.
