Patent number: 11611270Abstract: A method for trickle impregnation of a stator or armature of an electric machine with a synthetic resin curing under temperature increase comprises heating the stator or the armature from an initial temperature to a trickle temperature range of the synthetic resin; keeping constant the temperature in the trickle temperature range and introducing the synthetic resin into the stator or the armature; heating the stator or the armature to a curing temperature range; keeping constant the temperature of the stator or the armature in the curing temperature range and setting and curing the synthetic resin to a duroplast; and cooling down the stator or the armature. The trickle temperature range has lower temperatures than the curing temperature range. The method includes inductively heating the stator or the armature. The stator or the armature may be disposed in an impregnation device.Type: GrantFiled: February 18, 2018Date of Patent: March 21, 2023Assignee: GEHRING TECHNOLOGIES GMBH + CO. KGInventors: Jens Berthold, Stefan Schneider, Richard A. Rasp
