Abstract
The present invention relates to a kit for an electric motor having a rotary encoder for determining the position of the motor shaft of the electric motor. A kit is proposed by which simple and precise positioning of a sensor of the rotary encoder on the electric motor, good protection of the sensor, and simple assembly are possible. To this end, the invention proposes that the kit includes an electric motor and a rotary encoder having a solid measure and having a sensor having sensor electronics, wherein the solid measure of the rotary encoder can be applied to a motor shaft at a reverse end face of the electric motor and protruding therefrom, the sensor of the rotary encoder is embedded with the sensor electronics in a plastic disc, a motor-side mounting element is disposed at the reverse end face of the electric motor, and the plastic disc comprises a sensor-side mounting element designed to be complementary to the motor-side mounting element.
