摘要： A motor circuit for driving a motor having two independent sets of windings forming 3 or more phases, wherein each phase of a first set is paired with a respective phase of a second set. A first bridge driver circuit has a top side switch and a bottom side switch driving each phase of the first set, and a second bridge driver circuit has a top side switch and a bottom side switch driving each phase of the second set. First and second current determining means determine current flowing in each respective sets of windings independent of the current flowing in the other set of phase windings. A third current determining means is configured to determine the sum of the current flowing in each pair of the N pairs of phases of the motor.

摘要： Systems and methods are provided for braking a translator of a linear multiphase electromagnetic machine. The system detects a fault event. A polarity indicative of an electromotive force in determined in at least one phase of the linear multiphase electromagnetic machine caused by a motion of the translator. In response to detecting the fault event, the system causes, based on the polarity, a current to be applied to a respective phase of the at least one phase to cause a force acting on the translator that opposes an axial motion of the translator to cause the translator to brake. Braking includes causing the translator to reciprocate at a reduced velocity by opposing axial motion over one or more cycles. The system may use one or more of position information, current information, operating parameters, to brake, or may brake the translator independent of such information.

摘要： A control system to realize input power changing along with both loads and rotate speed by an inverter bridge dragging many sets of motors, is composed of a stator voltage regulating unit (1), a motor unit (2), a rotor speed control unit (3), an inverter bridge unit (4), a control drive unit (5) and a signal processing unit (6). By setting a power factor sensor, the phase voltage and phase current of the motor stator are acquired as a control signal to regulate the input power so as to make it change with loads. At the same time, by setting a voltage sensor and a current sensor, motor rotor phase voltage, rectifier output current, overvoltage protection current and chopper working current are acquired separately as a control signal to regulate the input power so as to make it change with the rotate speed, thus realizing input power changing along with both loads and rotate speed.

摘要： Phase currents of an inverter-driven electric machine are measured by mounting phase conductors of each respective phase current into a central passage of a respective flux core. A plurality of current sensors are mounted into a gap of each respective flux core to generate a respective plurality of current signals for each phase current. The Hall-effect devices are connected to a plurality of multi-channel op amp devices for conditioning the current signals such that each set of Hall-effect devices is connected to a different one of the op amp devices and such that each op amp device receives one current signal corresponding to each phase current. Thus, a valid conditioned current signal corresponding to each phase conductor is generated by the op amp devices unless there are multiple simultaneous failures of the Hall-effect devices and the op amp devices.

摘要： An exciter assembly for supplying a field current to the rotor windings of a superconducting synchronous machine includes a pulse transformer having a stationary primary winding and a secondary winding that is mounted to the rotor of the superconducting synchronous machine for rotation therewith. A switched mode power supply supplies a pulsed voltage to the primary winding of the pulse transformer. The pulsed voltage developed at the secondary winding of the pulse transformer is supplied to the rotor windings through a rectifier semiconductor device and a pair of transfer leads. The rotor windings and a flywheel semiconductor device are located inside a cryogenic chamber or cryostat. The flywheel semiconductor device is connected in parallel with the rotor windings and operates in unison with the rectifier semiconductor device in order to provide synchronous rectification of the switched mode power supply output. The switched mode power supply and both the primary and secondary windings of the pulse transformer are located outside the cryostat.
