<p>A method and system for advancing the state of commutation of an electronically commutated brushless D.C. motor. Impending motor stall is detected by measuring current flow through the motor windings to ascertain magnetic saturation. Upon such detection, a time sequence is started and if a change of state has not occurred within the time sequence, the state is advanced to the next succeeding state.</p> |
