    torque at standstill with sHFI

    silent HFI uses phase modulation instead as audible amplitude modulation

    The motor starts from standstill with the maximum permissible torque
    and is fully controlled even at low speeds.

    From a certain speed, the control switches to observer mode.






    IPD (initial position detection) followed from

    silent HFI signal






    the current shape of silent HFI

    the first pulses for IPD
