ABSTRACT:
A method and system for determining the commutation position in a DC machine using a single-bit rotor sensor and the back EMF signal from a stator winding by calculating a delay value, which is equal to the time elapsed between detection of the position signal and the back EMF signal, and establishing commutation after a period of time equal to the delay value has elapsed from when the position signal is detected.
