Abstract
A motor vehicle auxiliary assembly electric motor includes a motor stator with stator coils. The motor stator is electronically commutated. A control electronics system drives the stator coils and is potted in a cast body. An electronics chamber is closed-off and has the control electronics system and the cast body arranged therein. A gas chamber is arranged adjacent to the cast body. A pressure equalization element ventilates and vents the gas chamber. An aeration shaft is arranged to pass through the cast body and fluidically connects the gas chamber to the atmosphere. The pressure equalization element is fluidically associated with the aeration shaft.
