Abstract
A method for controlling a single coil BLDC motor having an electrical time constant, the method includes EHP sequences having a pulse train with at least two driving pulses of a same polarity, each driving pulse comprises: applying a driving signal during a torque generating period (TGP), followed by a non-torque generating period (NTGP); monitoring the phase current, wherein the sensing window lasts at least during a time constant, which is the electrical time constant or an approximation thereof, if the sensing window is during the TGP, and wherein the sensing window minimally lasts until the phase current has reduced to less than half the maximum phase current which was generated during the TGP if the sensing window is during the NTGP; determining parameters for the ongoing EHP, and/or for at least one next EHP sequence based on the obtained phase current information.
