Title:
STATOR AND ROTARY ELECTRIC APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/210704
Kind Code:
A1
Abstract:
The present invention relates to a stator and a rotary electric apparatus comprising same. Multiple conductors constituting each of multiple parallel circuits are formed to be two types of hairpins having different slot pitches, namely a long slot pitch and a short slot pitch, and the conductors of the two types of hairpins are alternately arranged along the circumferential direction on every layer and are wired in intersecting directions. Therefore, the multiple conductors constituting each parallel circuit are evenly distributed in every slot and every layer so as to form a balanced parallel circuit, thereby, due to the balanced parallel circuit, enabling each parallel circuit to have the same interlinkage magnetic flux and enabling an electric current to flow along the multiple parallel circuits in balance.
