DEVICE FOR IMPREGNATING VARNISH INTO HAIRPIN IN STATOR OF ELECTRIC MOTOR

WIPO Patent Application WO/2024/071913

A1

This invention relates to an impregnation device for impregnating varnish into portions of a hairpin which is mounted on a stator of an electric motor and exposed from both lengthwise end portions of the stator. The impregnation device of the invention comprises: a first support mechanism abutting around an outer surface of a stator core to support the stator; a second support mechanism on which the first support mechanism is rotatably mounted around the axis of the stator; a first rotation mechanism for rotating the first support mechanism around the axis of the stator core; a heating mechanism which extends through the stator core, moves in the axial direction of the stator core, and is placed on the portions of the hairpin exposed from both end portion in the longitudinal direction of the stator core to heat the portions of the hairpin; a movable mechanism for moving the heating mechanism in the axial direction of the stator core; and an application tool for applying varnish to the portions of the hairpin exposed from both ends in the longitudinal direction of the stator core.
