Abstract
A winding separation method of separating a winding from an electric motor stator that includes a stator core and a coil attached to the stator core and has insulating paper between the winding of the coil and the stator core, which the winding is covered with a coating having insulating properties, which method includes: a heating step of heating the electric motor stator; a cutting step of cutting a predetermined welded portion of the electric motor stator and a portion of the winding; and an extraction step of extracting the winding from the stator core, in which a heat-resistant temperature of the insulating paper is lower than a glass transition temperature of the coating of the winding.
