A sensorless control for operating an inverter coupled to a switched reluctance machine includes an instantaneous position generation circuit that develops a signal for controlling commutation of the switched reluctance machine. The instantaneous position generation circuit includes a digitally controlled counter which provides a direct interface between a position estimation circuit and commutation logic for the inverter.

[ We claim:] [1.] Apparatus for converting a first machine position signal representing a series of indications of position of a machine at a first position update rate into a second machine position signal representing a series of machine position indications at a second position update rate greater than the first position update rate, comprising:a counter having a clock input responsive to a clock signal, an increment input and an output at which the second machine position signal is developed; andmeans responsive to the first machine position signal and coupled to the increment input of the counter for deriving an increment signal for the counter.
