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.
Claims20
A cover plate for an electric motor, comprising:
- a brush array;
- at least one interference suppression device;
- and
- at least one additional electronic component is earned on the cover plate, the at least one additional electronic component including temperature-sensitive means for providing a temperature-dependant signal for pulse-width modulated control of the electric motor.
A cover plate for an electric motor, comprising:
- a brush array;
- at least one interference suppression device;
- and
- at least one additional electronic component carried on the cover plate;
- wherein the at least one additional electronic component forms a diagnostic circuit.
A cover plate for an electric motor, comprising:
- a brush array;
- at least one interference suppression device;
- and
- at least one additional electronic component carried on the cover plate;
- wherein the at least one additional electronic component forms a diagnostic circuit;
- and wherein the diagnostic circuit has at least one voltage divider, where a first node of the voltage divider is connected to a first reference potential in the diagnostic circuit, and a second node of the voltage divider is connected to a second reference potential of the diagnostic circuit.
