    Abstract: A method for identifying an operational phase of a motor (203) may include obtaining a first value of a signal that is indicative of the operational phase of the motor (203) and obtaining a second value of the signal after a period of time has expired. The method further includes identifying a first operational phase of the motor (203) if the second value exceeds the first value by a non-negative first threshold value. A second operational phase of the motor (203) is identified if the second value does not exceed the first value by the first threshold value. The first and second operational phases may correspond to relative positions of a motor’s rotor and stator, such that periods of energization may be identified for producing motoring or regenerative torque.

    Abstract: A method for collecting operational parameters of a motor may include controlling the energization of a phase winding of the motor to establish an operating point, monitoring operational parameters of the motor that characterize a relationship between the energization control applied to the motor's phase winding and the motor's response to this control, and collecting information of the operational parameters for the operating point that characterizes the relationship between the applied energization control and the motor's response. The collected information characterizing the relationship between the applied energization control and the motor' s response may be employed by a neural network to estimate the regions of operation of the motor. And a system for controlling the operation of motor may employ this information, the neural network, or both to regulate the energization of a motor's phase winding during a phase cycle.

    Abstract: A translation system, applicable in trains, elevators, aircraft launchers, rail guns, conveyors, door openers, machine tools and servo drivers, includes a first linear switch reluctance machine (LSRM)(100) having a stator (104) and a translator (102) each configured, positioned and proportioned for electromagnetic engagement with the other. The system further includes an assembly for selectable application of at least one phase of a multiphasic DC excitation to the LSRM (100) to produce a longitudinal or propulsive force between the stator (104) and translator (102). The system further includes an assembly for the substantially simultaneous application of at least two phases of the DC excitation to the LSRM (100) to produce a continual normal force between the stator (104) and the translator (102). A second LSRM (200) may be provided, positioned in quadrature to the first LSRM (100), and in electromagnetic engagement with it. A multi-phasic excitation of a stator and translator of the second LSRM (200) produces both a guidance force for the first LSRM (100) using error values generated by it and an additional propulsive force. Independent control of the phasic excitations for each of said propulsive, lift and guidance forces may be provided.

    Abstract: A power converter (500) for a switched reluctance motor or a permanent magnet brushless direct current (dc) motor including first and second partial circuits (553, 554) for forming multiple conduction circuits in cooperation with first and second phase windings (505, 508) of the motor. The contoller (704) also includes a switch (555) operable to open and close a first conduction circuit, which includes the first phase winding (551), and to regulate energization of the first and second phase windings of the motor through opening and closing the first conduction circuit. Control of the switch (555) provides four-quadrant operation of the motor through regulated energization of the first and second phase windings (551, 552).
