Abstract:
A control system for an electric motor comprising a stator having a plurality of stator coils and a rotor movable along the stator comprises a position detection device and a coil monitoring device. In this case, the position detection device is designed to generate position data representing a position of the rotor along the stator, and the coil monitoring device is designed to generate coil data representing a status of one or a plurality of the stator coils. The control system furthermore comprises a safety device designed to carry out a coordination between the coil data and the position data. Moreover, the safety device is designed to cause the electric motor to be transferred to a safe state if an error has been discovered during the coordination.
