Abstract
A system and method of motor control enable improved motor control by controlling a phase winding to float or enter a high impedance state prior to activating phase detection of the phase winding. Because the phase winding floats prior to phase detection, the effect residual current coupling in such phase can be mitigated and thereby help improve motor operation.
