Abstract

The invention relates to a method for impregnating bodies provided with windings, especially electrical machines. The body comprising the windings is dipped into a resin or a lacquer and inductively heated using an open induction coil. During the heating, the open induction coil is arranged above the body comprising the windings, an angular segment above the body forming a drip space.
