ABSTRACT:
The invention concerns a method for operating an electric motor (32) with which a microprocessor or microcontroller (23) and a nonvolatile memory (74) are associated, at least one operating data value of the motor (32) being automatically saved under program control in the nonvolatile memory (74) upon occurrence of an error. An electric motor for carrying out such a method is also described. The result of the invention is to increase the operating reliability of a motor, since the saved data can be polled from time to time or after occurrence of an error. The manner in which such errors are processed is also described.
