However, a mechanism dedicated to varnish dripping is required to support the stator coil from the inner diameter side after induction heating, and to change the posture so that the axis of the stator coil is oriented in the horizontal direction, and similar to the technique described in Patent Document 1, overflow from the stator may occur. Possibility of run-off varnish adhering to support mechanisms

The present invention relates to a varnish impregnation device which impregnates a varnish into a stator coil which is mounted on a stator core in which a slot is formed facing radially inwards. To prevent the varnish from adhering to the support mechanism of the stator, which comprises the stator coil mounted on the stator core, while efficiently and effectively heating the stator in order to impregnate the varnish into the stator coil, this varnish impregnation device is provided with: a support mechanism which, while gripping the stator, which comprises a stator coil mounted on a stator core, on the outer diameter side, supports the stator in a state in which the axial direction thereof is turned towards the horizontal direction and rotates the stator when rotated by a rotation device; a varnish dropping device which adds varnish dropwise towards the coil end portion of the stator which rotates while being supported by the support mechanism; and a stator radially inner heating device which is arranged in a cavity in the shaft center of the stator core of the stator supported by the support mechanism and which heats the stator from radially inside of the stator.
Description
technical field [0001] The present invention relates to a varnish dipping device and a varnish dipping method, and more particularly to a varnish dipping device and a varnish dipping method suitable for dipping a stator coil attached to a stator core with a varnish. Background technique [0002] Conventionally, a varnish dipping device and a varnish dipping method for dipping a stator coil attached to a stator core with varnish are known (for example, refer to Patent Documents 1 and 2). The varnish dipping device described in Patent Document 1 is provided with a support mechanism that supports a stator in which a stator coil is attached to a stator core, and allows the stator to rotate. This support mechanism has a workpiece rotation shaft inserted into a cavity formed at the axial center of the stator core, supports the stator on the inner diameter side of the stator using the workpiece rotation shaft, and rotates the workpiece rotation shaft. The stator rotates. [0003]...
