Abstract
A regulator may include an output element and an electric motor for driving the output element. The electric motor may have a rotor. A mechanical power transmission device may be located between the rotor of the electric motor and the output element. A rotor position sensor for determining a position of the rotor may be included. A multi-turn sensor may also be included, where the multi-turn sensor is configured to monitor rotation of at least one of the rotor and a rotating element of the mechanical power transmission device.
