Beschreibung
Zusammenfassung:	A drive system for a motor having a rotor and a phase winding (a, b, c) comprises; a drive circuit (8) including switch means associated with the winding a, b, c for varying the current passing through the winding; rotor position sensing means (34) arranged to sense the position of the rotor; control means (30) arranged to provide drive signals to control the switch means; a power input for connection to a power supply at a nominal voltage; and boost means (26) in electric communication with the power input and power output, and controllable to boost the nominal voltage to a higher voltage for application to the winding.
