Abstract
A converter motor includes a braking resistor, and an electric motor with a junction box. The junction box is formed from a bottom part and a cover placed on the bottom part, and a printed circuit board of the converter is fastened to the cover. A braking resistor is thermally conductively connected to the bottom part and/or fastened on the bottom part, and a metal sheet is connected to the bottom part. The braking resistor is arranged on that side of the metal sheet which is averted from the printed circuit board.
