Abstract
A method for insulating a coil of a rotary electric machine resulting in improved insulating properties at critical coil ends. A mica sheet or mica tape is wound around a part of each coil to be inserted into a slot cut in an iron core of the rotary electric machine to thus form a first insulating layer. The coils thus treated are inserted into respective slots and are connected together and to external terminals as required. Each coil end is then covered in its entirety with a thermosetting resin. The thermosetting resin is hardened by heating to form a second insulating layer.
