Abstract: The invention relates to a method and a heating device (1c) for inductively heating a stator (2) or armature (3) of an electric machine, in particular before and during trickle impregnation thereof. In addition, the invention relates to an impregnating device (50) in which this heating device (1c) is integrated. According to the invention, it is provided that the heating takes place inductively by electromagnetic fields of different frequencies. For this purpose, it is provided in the case of the heating device (1c) that it has at least one electromagnetic inductor (18, 21, 24) which is disposed coaxially or axially parallel with respect to the longitudinal axis (7) of the stator (2) or armature (3) and which inductively heats said stator or armature, and that the at least one inductor (18, 21, 24) is designed to generate at least two electromagnetic fields of different frequencies.
Abstract: The invention relates to a device and a method for transferring conductor parts, in particular plug-in winding elements bent into a U-shape, also known as hairpins, into a desired arrangement.

Abstract: 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.
