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 use in exciting a winding of the electric machine. Control signals for each electrical half-cycle of one mechanical cycle are generated by the drive controller in response to a single edge of a signal output by the position-sensor.
