    Abstract: A decentralized motor drive arrangement provides high-voltage operational power and low-voltage standby power from a centralized distribution unit to remote motor drives using the same pair of interconnection power wires. The distribution unit includes a low- voltage power source which has one output terminal diode coupled to one of the output terminals of a high-voltage power source to form one output wire of the distribution unit. The other output terminals of the low-voltage and high-voltage power sources are directly coupled to form the other distribution unit outgoing power wire.

    Abstract: This invention aims at developing an Induction Motor that consumes less power than existing Induction Motors. An efficient Induction motor comprises a stator that includes three field windings and a rotor that includes rotor conductors short-circuited at both ends by end rings located at both ends of rotor. A field winding comprises a number of pairs of North pole and South pole. There are three full-wave rectifiers. Each of the three full-wave rectifiers converts a phase current of a three phase alternating current supply into a unidirectional current varying with time and delivers the converted current exclusively to a field winding. As a result, poles of the field winding generate fluctuating magnetic flux. A rotor conductor cuts said fluctuating magnetic flux thereby inducing an emf in said rotor conductor and consequently generating current in it. The direction of said magnetic flux and the direction of said current flowing in said rotor conductor are perpendicular to each other. Said rotor conductor moves in a direction perpendicular to both the direction of said magnetic flux and said rotor conductor current thereby rotates the rotor.

    Abstract: A method and an apparatus for sensorless profiling of a current waveform in a switched-reluctance motor (SRM) is disclosed. The apparatus comprises a switched-reluctance motor having at least one stator pole and at least one rotor pole, a phase inverter controlled by a processor, a load, a converter and a software control module at the processor. The current waveform sets a target magnitude for a programmable dwell angle that scales a programmable waveform shape. Slope of the current is continuously monitored which allows the shaft speed to be updated multiple times and to track any change in speed and fix the dwell angle based on the shaft speed. The method reduces the overall radial force magnitude by compensating nonlinear torque production thereby reducing the acoustic noise reduction and torque ripple which results in computational efficiency of the SRM.
