摘要： A stator core including field slots housing field windings and armature slots housing armature windings is provided. Permanent magnets are housed in the respective armature slots. Field windings face to the permanent magnets directly or via the stator core on the outer and inner circumferential sides. A coil end of one of the armature windings straddles the predetermined one of the field slots and passes over the axial end face of each of the permanent magnets in the corresponding one of the field slots over which the coil end straddles.

摘要： An electromagnetic generator comprises one or more flux assembly having at least one coil and at least one magnetic field source separated by a gap. An interference drum has a sidewall at least partially positioned inside the gap and comprising at least one magnetic field permeable zone and at least one magnetic field impermeable zone. The interference drum is movable relative to the at least one coil and to the at least one magnetic field source to alternatively position the at least one magnetic field permeable zone and the at least one magnetic field impermeable zone of the sidewall inside the gap. When the interference drum is moved, magnetic flux is created in the coil, and induces electrical current to flow into the coil. The coil may be connected to an external circuit, such that the electrical current may flow through the external circuit.

摘要： An electromagnetic rotary drive includes a contactlessly magnetically drivable rotor that is coil-free and free of permanent magnets and that includes a magnetically effective core, and a stator by which the rotor is contactlessly magnetically drivable about a desired axis of rotation in the operating state. The stator has a plurality of coil cores of which each includes a bar-shaped longitudinal limb extending from a first end in a direction in parallel with the desired axis of rotation up to a second end, all the first ends being connected by a reflux of windings generate an electromagnetic rotational field of which each surrounds one of the longitudinal limbs. The coil cores include a plurality of permanent magnets by which a permanent magnetic pre-magnetization flux can be generated.

摘要： A DC electric rotating machine, such as a starter of an automotive vehicle, includes a stator with salient poles having at least four poles distributed uniformly over the circumference of the stator, a rotor disposed inside the stator, a set of brushes adapted for the electric supply of the rotor, and at least two geometrically opposed salient poles. Each pole includes at least one substantially radial slot in a plane parallel to the axis of rotation of the rotor and preferably passes through the axis of the rotor. By minimizing the reaction fields of the armature, utilization of the magnetic material of the parts of the stator is balanced and a harmful armature reaction effect, which increases saturation of the polar parts of the inductor and which leads to reduction in the driving magnetic torque, is mitigated.

摘要： The invention relates to an electrical power motor-generator excited by magnetic transference, and which further comprises a stator (1) and a rotor (2) with an external core (3) stationary relative to the stator and rotor, said external core (3) comprising: an outer axial part, or axial armature (6) joined to the stator (1), an inner part that communicates through an air gap (4) with the rotor (2), a third part, disk (8), that joins the other two parts, where the rotor does not have any excitation coils, and hence no rings or collector brushes. The outer core (3) has an axial permanent magnet (12) and permanent magnets (10) on the outer axial part (6) thereof, and electromagnets (11) in the other two parts or on the disk (8). The rotor does not have brushes to create a magnetic field, which is created by the magnets and coils of the outer core (3), the magnetic flow transmitting the induction flow to the rotating rotor, through an air gap, thus dispensing with rings and collector brushes.

摘要： A high-efficiency magnetic inductor rotary machine in which eddy current loss is reduced even if driven at super-high-speed rotation, and a fluid transfer apparatus that uses the same. In the magnetic inductor rotary machines, first and second stator cores are disposed coaxially such that circumferential positions of teeth are aligned, and first and second rotor cores are fixed coaxially to a rotating shaft such that salient poles are offset by a pitch of half a salient pole circumferentially, and are disposed on an inner peripheral side of the first and second stator cores. A salient pole width of the salient poles of the first and second rotor cores is configured so as to be greater than an opening width of slots of a stator.
