Abstract: Measures, including apparatus, methods and computer program products, for generating an output signal with a defined waveform shape are provided. A plurality of switched inductor arrangements are each connected in parallel to generate a combined output signal. Each of the switched inductor arrangements are selectively enabled, wherein the number of enabled switched inductor arrangements is varied to define a waveform shape of the combined output signal.

Abstract: An electric motor apparatus comprising: a stator component and a rotor component rotationally mounted coaxially with and within the stator component. The stator component and the rotor component each comprise windings configured to generate an electromagnetic field from an electric current. The electric motor further comprises an intermediate screening component rotationally mounted between the stator component and the rotor component and configured to provide at least some magnetic screening between the rotor component and the stator component. The intermediate screening component comprises at least some magnetically active sections configured such that changing magnetic fields generated by changing electric currents in the windings on either the rotor component or the stator component generate a force on the magnetically active sections causing the intermediate screening component to rotate; and control circuitry for independently controlling power supplied to the windings on the rotor component and the stator component in dependence upon a desired output rotational speed.

Abstract: A driver circuit for driving an electrical motor coil is provided which comprises combined switched inductance boost voltage converter circuitry and switched inductance buck voltage converter circuitry. An input node of the driver circuit is provided to be coupled with the electrical motor coil, which provides the inductive element of both the boost and buck circuitry. Further the boost and buck circuitry share a storage capacitor, which provides the capacitive element of each circuitry, and a voltage developed across the storage capacitor by the boost circuitry forms an input of the switched inductance buck voltage converter circuitry. Bidirectional driving of the electrical motor coil is thus provided from a driver circuit which only need be supplied with a single unidirectional supply and the current drawn from that supply is significantly reduced because of the manner in which the boost and buck circuitry operate synergistically to recycle electrical power which is moved back and forth between the electrical motor coil and the storage capacitor. A corresponding driver board, electrical motor driver apparatus, method of operating a driver circuit and apparatus are also provided.

Abstract: An electrical motor system comprises a switched reluctance electrical motor comprising a rotor section and a stator section, the rotor section comprising a plurality of rotor teeth and the stator section comprising a plurality of stator teeth, the stator teeth wound with respective coils. Coil driver circuitry is coupled to the coils of the stator teeth and controls an independent phase of electrical power to each coil of the plurality of stator teeth. The coils of the stator teeth each have an inductance which absorbs electrical energy provided to that coil by the coil driver circuitry and subsequently releases at least a portion of the electrical energy back to the coil driver circuitry when that coil is not being actively driven by the coil driver circuitry. The coil driver circuitry comprises an electrical energy store configured to store the portion of the electrical energy released back from the inductance of each coil and the electrical energy provided to each coil of the stator teeth by the coil driver circuitry is augmented by the electrical energy stored in the electrical energy store.
