  • Method and device for determining the rotor position and speed of a rotating field machine
    Patent number: 9966884
    Abstract: A method for determining the rotor position and the rotational speed of a rotating field machine, including, based on Hall sensor signals, a step of determination of a sector in which a rotor of the rotating field machine is situated and a step of determination of a preliminary rotational speed of the rotating field machine. In a step of determination, the rotor position and the rotational speed are determined based on the sector and on the preliminary rotational speed, an observer of the rotating field machine being used at least for the determination of the rotational speed.
    Type: Grant

  • Control device and method for controlling an induction machine
    Patent number: 9680403
    Abstract: A control device for an induction machine includes an angle determining device designed to determine a rotor angle of the induction machine without requiring use of sensors. The angle determining device generates measuring voltage pulses which can be selectively used to replace control voltage pulses used to control the induction machine. Machine currents generated by the measuring voltage pulses can be used to determine a rotor angle without interrupting the control voltage pulses and/or operation of the induction machine.
