Abstract

A cover plate for an electric motor which has a brush array and interference suppression devices has additional electronic components mounted directly on the cover to determine the speed of the electric motor and for diagnosis. Contact with the interference suppression devices and the additional electronic components is achieved through electrical conductors which are located directly on the cover plate. Flexible use of the electric motor is ensured through the high temperature stability of the cover plate.
