A control unit for use in controlling a switched reluctance motor (SRM) for clockwise rotation in a clockwise-rotating electric supercharger and anti-clockwise rotation in an anticlockwise-rotating electric supercharger. Each SRM has a rotor 101 and a multiplicity of pairs of stator coils 103. The control unit is configurable in a first mode of operation, for controlling the SRM in the clockwise-rotating supercharger, and the control unit is also configurable in a second mode of operation, for controlling the SRM in the anti clockwise-rotating supercharger. In that second mode of operation the control unit is configured to energise, at the same time the first and second pairs 105A/105C of the stator coils, turn off the second pair 105C of coils, while leaving the first pair 105A energised; and after the rotor is caused to rotate in the anti-clockwise direction, subsequently accelerating the rotor. |
