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： Provided is a diagnostic device for a coil including a voltage application unit applying an impulse voltage to the coil; a response voltage detection unit detecting a response voltage from the coil with respect to the impulse voltage; an index calculation unit calculating a determination index indicating an electrical feature of the coil based on the response voltage; and a determination unit determining whether there is an abnormality in a target coil to be diagnosed by comparing the determination index of a reference coil that is the coil that is normal and the determination index of the target coil. At least one of a zero cross point at which the response voltage intersects with a reference voltage and a peak voltage on a positive side and a negative side of the response voltage is used as the determination index, in addition to a circuit constant of the coil.
