Abstract
An insulating paper piece for electric motors, capable of improving both electrical insulation between a coil and a stator core and electrical insulation between ends of coils of different phases without adversely affecting ease of coil insertion or the space taken up for the coil. A single insulating paper piece for electric motors contains at least two slot cell portions arranged in two slots of the stator core in which portions of one single pole coil are to be inserted, with two phase insulation portions arranged to connect respective ends of the two slot cell portions to form loops and disposed to face directly against coil ends of the single pole coil. The phase insulation portions comprise overlapping widthwise portions extended from both ends so that when a plurality of the insulating paper pieces for electric motors are mounted on the stator core, the respective overlapping portions of the adjacent insulating paper pieces overlap one another.
