Abstract
A control system for an electric machine, the control system including a position sensor and a drive controller. The drive controller generates one or more control signals for exciting a winding of the electric machine in response to edges of a signal output by the position sensor. Moreover, the drive controller generates control signals in response to an edge that occurs within a time window. The time window starts at a time when control signals are generated and has a length less than the electrical half-cycle period.
