Abstract
A drive device having an electric motor with a device for field oriented control of the electric motor and a method for operation thereof is disclosed. An error monitoring of a transducer on the electric motor is achieved by a comparator device for comparing a transducer signal of the transducer on the electric motor with a calculated parameter of the field oriented control, the comparator device recognizing a transducer error and/or a coupling error. The coupling error relates to a coupling for mounting the transducer on the electric motor.
