Abstract
In a method of heating a stator, a first induction coil is disposed near one of the coil ends of the stator, and a second induction coil is disposed near the other, and the first induction coil and the second induction coil are electrically energized, whereby the induction-heating of the stator is performed as a pre-heating step prior to the resin molding step of the coil ends. According to this method, a first movement unit for moving the first induction coil and a second movement unit for moving the second induction coil are provided, the first induction coil is moved by the first movement unit and the second induction coil is moved by the second movement unit for induction-heating of the stator.
