    Abstract: A high phase order induction machine wound and permitted by coil symmetry to operate at fewer than the magnetically optimal number of poles is constrained by symmetry to be a two pole machine and be capable of operating on odd harmonics only, but with back-iron, end rings, and rotor core optimized for 10 pole operation, might be used normally in ‘5th harmonic’ mode, with ‘7th harmonic’ utilized to engage the ‘mesh effect’. Such a machine thus appears to be operating in the ‘1.4 harmonic’. A high phase order induction machine driven by a second harmonic drive, in which a symmetry imposed by full span windings is broken. This may be most simply accomplished through the use of short pitch windings. Other possible approaches include using non-wound slot drive, and using toroidal windings which localize coils to individual slots.

    Abstract: A wheel design is provided for an aircraft landing gear wheel that is configured to maximize the space available within a landing gear wheel well to support a geared motor assembly that drives the aircraft wheel when the aircraft is on the ground. The wheel includes inboard and outboard support walls that are spaced apart a selected distance along the wheel axle so that the geared motor assembly components are substantially completely contained within the wheel space defined by the support walls. The preferred motor driver assembly includes an electric motor and a gear and clutch assembly operatively connected to the wheel to drive the wheel and move the aircraft on the ground. The wheel and motor driver assembly described herein may be retrofitted in an existing aircraft wheel without changing existing landing gear components, including tires, piston, and axle.

    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.

    Abstract: In the present invention, several polyphase devices are connected together: an inverter, and electrical rotating machine, and a resistive load or braking resistor. The purpose of the resistive load is to dissipate excess electrical power which may be produced when the inverter acts to slow down the rotating machine, causing the rotating machine to act as a generator. In common art, this resistive load is a single DC resistor coupled to the DC link of the inverter via a separate resistor control transistor. In the present invention, the resistive load is a mesh connected array of resistors, and is electrically connected to the same inverter output terminals that the rotating machine is connected to. When it is desired that the resistors absorb energy, for example from a braking operation, then the harmonic content of the inverter output is adjusted, thus placing voltage differences across the resistor array and causing current to flow in the resistors.
