  • Patent number: 10066967
    Abstract: A method for detecting rotor position for a single coil DC motor or 2-coil DC motor with non-parallel windings, with no need of Hall position sensor. The method comprises applying a first respectively second probe pulse for generating a first response pulse having a first direction or polarity and a second response pulse having a second direction or polarity. The probe pulses are adapted so they do not substantially move the rotor with respect to the stator, but affect the magnetic properties of the stator. By comparing the measured effects caused by the probe pulses, the initial position of the rotor with respect to the stator is determined. A method for start-up, a motor driver circuit, and a motor assembly comprising said motor and driver circuit are also provided.
