Title: Insulated core for rotary electric machine
Inventor: GOHISA TOSHIO
IPC: H02K3/34
Filed: 1980-08-08
Abstract: PURPOSE:To improve the insulating withstand voltage of the insulated core for a rotary electric machine and to facilitate a coil inserting work by inserting a U-shaped sheetlike insulator into the slot of the core and forming a continuously insulating layer by a powder coating from the end of the slot to the end face of the core.
