    Abstract: A synchronous machine control device includes a flux command generator, a magnetic flux estimator, a divider, a flux controller and γ- and δ-axis armature current controllers. The flux command generator produces a flux command from the synchronous machine turning speed. The magnetic flux estimator calculates the magnitude and phase of armature flux linkage from armature currents and field current taking into consideration magnetic fluxes produced by permanent magnets. The divider produces an armature current command by dividing a torque command by the armature flux linkage. The flux controller determines a field current command based on an error of the magnitude of the armature flux linkage from the flux command. The γ- and δ-axis armature current controllers control the synchronous machine such that both an error of an armature current in a direction perpendicular to the armature flux linkage direction from the armature current command and an armature current in the armature flux linkage direction become zeros.

    Abstract: A multi-function apparatus and a method for performing the functions of a starter, alternator and engine stabilization system for an engine of a motor vehicle. The apparatus comprises a rotor, a stator and a switching/detection system associated with the stator. The stator comprises three independent stator sectors which each comprise a plurality of independent stator coils. The rotor comprises a plurality of rotor poles about its periphery. The rotor is secured to the flex plate of the engine and the stator sectors are secured to the bell housing of the vehicle's power train. The stator coils each protrude through opening formed in the bell housing such that the rotor poles are closely adjacent the stator coils without contacting the stator coils as the rotor rotates. The switching/detection system is used to detect the positions of the rotor poles relative to the stator coils and selectively energizes various groups of stator coils for very brief, predetermined time intervals to cause movement of the rotor and therefore assist in starting of the engine. In the alternator mode energy generated in the stator coils is returned to the vehicle's battery. In the engine stabilization mode selected groups of stator coils are periodically energized to assist in smoothing out the idle of the engine of the vehicle at low idle speeds. The apparatus and method can also be used to propel the vehicle for distances determined by the energy stored in the vehicle battery, to act as a supplemental "power booster" and as a brake for effecting powertrain braking.

    Abstract: A turbogenerator/motor controller with a microprocessor based inverter having multiple modes of operation. To start the turbine, the inverter connects to and supplies fixed current, variable voltage, variable frequency, AC power to the permanent magnet turbogenerator/motor, driving the permanent magnet turbogenerator/motor as a motor to accelerate the gas turbine. During this acceleration, spark and fuel are introduced in the correct sequence, and self-sustaining gas turbine operating conditions are reached. The inverter is then disconnected from the permanent magnet generator/motor, reconfigured to a controlled 60 hertz mode, and then either supplies regulated 60 hertz three phase voltage to a stand alone load or phase locks to the utility, or to other like controllers, to operate as a supplement to the utility. In this mode of operation, the power for the inverter is derived from the permanent magnet generator/motor via high frequency rectifier bridges. The microprocessor monitors turbine conditions and controls fuel flow to the gas turbine combustor.

    Abstract: A conventional motor controlling circuit is adapted to control an inverter that drives a permanent magnet generator as a motor to spin an engine to a speed sufficient to permit the engine to start. The commutation frequency is adjusted as a function of speed utilizing an automatic commutation frequency adjustment circuit. This circuit has multiple commutation frequency ranges that overcome a large initial bearing drag during low speed operation while still permitting high speed operation. The automatic commutation frequency adjustment circuit preferably generates first and second voltage ramps that overcome the initial bearing drag and accelerate the generator at a rate fast enough for sufficient back EMF to be generated for a closed-loop commutation phase. A speedup circuit operates during the closed-loop commutation phase to achieve the high speeds typically necessary for engine starting. The inventive circuits even permit a turbine type engine to be successfully started.
