  • Device and Method for the Detection of the Rotor Position at Low Rotational Speeds or at a Standstill
    Publication number: 20120229119
    Abstract: The invention describes a circuit arrangement and a method for the detection of the rotor position at low rotational speeds of rotors or at a standstill. For this, an HF signal is fed into the neutral point (zero sequence) and the rotor position is detected via the distribution of the HF signal in the coils (non-zero sequence).
