摘要： A varnish impregnation apparatus that includes a support that supports a stator, in which the stator coil is mounted to the stator core, with an axial direction of the stator directed in a horizontal direction while grasping a radially outer side of the stator, and that is rotationally driven by a rotary device to rotate the stator; a varnish dropping device that drops the varnish toward a coil end portion of the stator which is rotated while being supported by the support; and a heater disposed in a cavity portion provided at an axial center of the stator core of the stator supported by the support to heat the stator from a radially inner side of the stator.

摘要： A stator heating apparatus that includes a support that supports a stator in which a stator coil is mounted to a stator core and that is driven by a rotary to rotate the stator; a first heater that includes an induction coil inserted into a cavity portion provided at an axial center of the stator core of the stator supported by the support to be disposed to heat the stator through induction heating, the first heater heating the stator from a radially inner side of the stator; and a second heater that includes a hot-air outlet port that blows hot air toward an outer surface of a coil end portion of the stator supported by the support to heat the stator using the hot air, the second heater heating the stator from a side of the outer surface of the coil end portion, wherein the stator is heated by the first heater and the second heater.
