摘要： An electric motor comprises a stator presenting a first surface. A rotor is rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the first surface of the stator. The first surface of the stator defines a plurality of slots in spaced relationship with one another to define a plurality of spaced teeth between the slots. At least one electrical conductor is disposed in each of the slots and configured to selectively create a moving magnetic field for acting upon the rotor for providing rotational movement of the rotor. A portion of the at least one electrical conductor extends substantially into radial alignment with, or past the first surface of the stator to at least partially define a stator raceway of the stator for engaging the rotor raceway of the rotor during relative radial movement between the rotor and the stator.

摘要： A motor-driven compressor includes an inverter device. The inverter device includes a noise reducing unit. The noise reducing unit includes common-mode choke coils and a smoothing capacitor. The common-mode choke coils include a first coil and a second coil. The first coil includes a first core, a first winding, and a second winding. The first core includes a first straight portion and a second straight portion. The second coil includes a second core, a third winding, and a fourth winding. The second core includes a third straight portion and a fourth straight portion. The first coil and the second coil are arranged side by side such that a current flowing through the first winding and the third winding generates an annular magnetic flux that passes through both of the first straight portion and the third straight portion.

摘要： A damper finger segment is radially disposed between a retaining ring and a damper ring arrangement at a rotor end of a generator arrangement, in particular of a high power turbogenerator, having a multitude of plate-like finger elements with a longitudinal extension and arranged parallel to each other. Each neighboring pair of finger elements encloses a gap and all finger elements are joined at one end of each finger element by a band-like strip section having a longitudinal extension being oriented orthogonally to the longitudinal extension of the finger elements. At least one slot is provided in each plate-like finger element and/or in the band-like strip section. The at least one slot has a slot axis oriented parallel to the longitudinal extension of the plate-like finger elements.

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.
