Abstract
A sensor device for determining a position ϕof a rotor of an electrical machine, for example an electric motor or electric generator. The sensor device comprises a number r of sensors, which detect the magnetic field generated by the rotor and/or a permanent magnet rotating with the rotor, and an electronic circuit which is configured The invention further concerns a control device for an electric motor with such a sensor device.
