摘要： PROBLEM TO BE SOLVED: To solve the problem that soldering quality is deteriorated due to disconnection caused when an insulating coating of an electric wire is peeled off, or the remainder of the insulating coating.SOLUTION: According to a method of peeling an insulating coating at a winding wire end portion of a winding wire wound around a magnetic pole of a stator, a tension-applied state is established by pulling the winding wire end portion, and the insulating coating is peeled off by moving an insulating coating peeling device whose cutting edge is rotated. This method allows the insulating coating to be peeled off without disconnecting the electric wire. The disconnection caused when the insulating coating is peeled off can also be prevented by employing aluminium having smaller strength than a copper wire or iron wire as a conductor for the winding wire.
