摘要： A rotating field machine (200) including a stator (140) and a rotor (150) are provided. In particular, a dual-winding rotating field machine (200) in which the stator (140) includes two separate windings can be provided. In one example implementation, the stator (140) can include an excitation winding (220) configured to control an excitation current and a power winding (230) configured to control power flow to an electrical system. The dual-winding rotating field machine (200) can further include a starting mode and a generating mode. During the starting mode, both the excitation winding (220) and the power winding (230) can be coupled to one or more switching power converters (170). During the generating mode, the power winding (230) can be coupled to a variable frequency bus and the power converter (170) can be used to manage excitation power only.

摘要： A generator rotor assembly can include a diode holder configured to hold one or more diodes. The diode holder can be formed of a first material having a first coefficient of thermal expansion (CTE). The assembly can include a rotor housing configured to hold the diode holder within the rotor housing. The rotor housing can be formed of a second material having a second CTE. The second CTE is different than the first CTE. The assembly can include one or more CTE compensation spacers interfacing the diode holder to the rotor housing such that the diode holder and the rotor housing are connected via the one or more CTE compensation spacers. The one or more CTE compensation spacers can be configured to have a third CTE different than the first CTE and the second CTE to compensate for relative length change between the diode holder and the rotor housing to prevent and/or reduce temperature induced stress growth at the interface of the diode holder and the rotor housing.

摘要： An assembly that can enhance the power factor of synchronous reluctance (SynRel) machines. The assembly can include one or more pickup coils that are at least proximally adjacent to an outer periphery of a rotor that are structured to harvest energy in an air gap between the rotor and a stator. The harvested energy can be supplied to a rectifier that is electrically coupled to the pickup coils, and which can convert the harvested energy into DC excitation current. The DC excitation current can be provided to one or more DC field windings that extend through the rotor, such as, for example, through flux barriers in the rotor. The flow of the DC excitation current through the DC field windings can generate a flux that can be put in a rotor axis to enhance the power factor and torque rating of the SynRel machine.

摘要： A multi-degree-of-freedom electromagnetic machine includes a stator, an armature, and a control. The stator includes a first stator conductor, a second stator conductor, and a third stator conductor. The armature is disposed adjacent to, and is movable relative to, the stator. The armature includes an armature conductor and a plurality of magnets, where each magnet has at least one of its magnetic poles facing the surface. The control is coupled to the first, second, and third stator conductors, and is configured to supply direct current (DC) to the first, second, and third stator conductors, and to selectively amplitude modulate the DC supplied to one or more of the first, second, and third stator conductors, to thereby electromagnetically couple the armature conductor to the one or more first, second, and third stator conductors.

摘要： The present invention inhibits the voltage jump of a source voltage or an output voltage by an approach which is different from a conventional one. A logic circuit allows an H bridge circuit to be shifted among a plurality of states in a specific sequence. A compulsory regenerating circuit is configured to be switched between an enabled state and a disabled state; while being in the enabled state, the current that flows in from a ground line via the H bridge circuit and a motor coil to a power line back-flows to the ground line.
