    摘要: An adaptive control system for an electric motor has energization circuitry connected to phase windings of the motor for energization thereof and a controller for generating a control signal corresponding to a profile of an excitation current. The control signal is applied to the energization circuitry to control energization of the phase windings. The energization circuitry provides the excitation current to the phase windings from a power supply. For a present combination of torque and speed, the controller adaptively determine the profile of the excitation current optimal for achieving a particular motor control objective. Excitation current profiles may be optimized to achieve maximum efficiency, maximum torque, minimum torque ripple, minimum core loss, etc.

    摘要: The present invention offers a novel control system for a multiphase motor. The control system involves energization circuitry for energizing each phase winding, and a control circuit for defining phase currents for individual phases of the motor to generate control signals applied to the energization circuitry for energization of the phase windings. When at least one phase of the motor fails, a mode selection circuit enables the control circuit to operate either in a non-correction mode or in a fault-correction mode. In the non-correction mode of operation, phase currents for phases that remain operational are maintained unmodified. In the fault-correction mode, the phase currents for the remaining phases are modified in accordance with pre-set parameters.

    摘要: Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.

    摘要: A portable range extender can be used to supply electrical power to an electric vehicle operable by an electric traction motor. The portable range extender includes an engine, a dynamoelectric machine coupled to the engine by a shaft, an autonomous range extender controller for controlling operations of the range extender independently of a controller for the vehicle, and circuitry associated with the engine and machine. The range extender and its controlling circuitry are self contained within an enclosure. The enclosure is partitioned to form two sections, a first section housing the dynamoelectric machine and the second section housing the engine. Windows in the enclosure provide a path for air cooling of the range extender components. Air cooling is facilitated by a first set of cooling fins mounted on the rotor of the dynamoelectric machine at an end proximate an air inlet window, a second set of cooling fins mounted on the rotor of the dynamoelectric machine in the vicinity of an opening in the partition, and a third set of cooling fins mounted on the engine at the opposite side of the partition opening.

    摘要: A control system is provided for a multiphase motor having a plurality of stator phase components, each stator phase component comprising a phase winding formed on a core element, and a rotor. A plurality of motor control schemes are stored in memory or calculated dynamically during motor operation. Subject to user or system selection, one of the motor control schemes is selected by a controller for implementation. The controller generates control signals that are applied to energization circuitry for supplying current to the phase windings with a particular current waveform profile in accordance with the selected motor control scheme. The controller has an input terminal for receiving a user initiated torque command signal representing a desired motor torque. Each motor control scheme provides motor driving current that corresponds to torque command signals received at the controller input terminal. In an automatic mode, the controller accesses the appropriate control scheme to meet the torque tracking requirements of the system.
