Rotating electrical unit and method of producing the same
First Claim
Patent Images
1. A production method of a rotating electrical unit, comprising:
- a first process forming a coil by winding a flat conductor wire in a plurality of turns around a pre-forming member; and
a second process producing a stator by inserting the coil into three or more slots provided in a stator core of a rotating electrical unit so as to cross over the plurality of slots, wherein the flat conductor wire is wound around the pre-forming member so that a cross-section shape of the coil is matched approximately with a cross-section shape of the slots in said first process.

Abstract
A coil is formed by winding a flat conductor wire around a coil pre-forming tool in a predefined number of turns. The cross-section shape of the coil is made approximately the same as that of the slot in a stator core into which the coil is to be inserted. A stator of a rotating electrical unit is comprised by inserting the coil into a plurality of slots so as to cross over the plurality of slots.
