    Abstract: An apparatus for controlling the power output of an unthrottled engine has a variable gear ratio transmission connected between a mechanical load and the engine, and it has a controller for controlling the torque load on the engine, according to the power output required. The controller measures the torque output of the unthrottled engine at the power output required, and sets the gear ratio of the transmission to produce a torque load on the engine equal to the torque output of the engine. This means the unthrottled engine will reach an equilibrium with the mechanical load at the required power output. Controlling the unthrottled engine in this way involves receiving a signal describing the power output requirement, varying a gear ratio of the transmission, and establishing a torque equilibrium between the load and the engine.

    Abstract: This application describes a motor designed to operate as a reluctance machine at low speeds and as an induction machine at high speeds. The drive waveform is composed of one or more harmonics to be used to match the reluctance pattern of the stator-rotor, causing the rotor to rotate due to the reluctance effect, and one or more other harmonics to induce current in the rotor, causing the rotor to rotate due to the induction effect and the subsequent interaction of the stator and rotor magnetic fields. The two effects are generally not applied simultaneously.
