Abstract

The invention relates to a control device (1) for reducing electrolytic corrosion in a brushless direct-current motor (3). The control device (1) is designed to control phases (9, 11, 13) of the brushless direct-current motor (3). The control device (1) has a potential equalization connection (5) and a potential equalization line (7). The potential equalization line (7) is designed to connect the brushless direct-current motor (3) to the potential equalization connection (5). An anti-corrosion resistor (RK) is provided on the potential equalization line (7), which anti-corrosion resistor is designed to reduce a current flow between the phases (9, 11, 13) of the brushless direct-current motor (3) and the potential equalization line (7).
