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 electro-magnetic coupling system for transferring torque between a pair of coaxial spools of a gas turbine engine is provided. The system includes a first rotor rotatable with one of the spools, a second rotor rotatable with the other of the spools, and a stator. The first and second rotors and the stator are coaxial with each other. The second rotor operably couples the first rotor and the stator. The first rotor carries a plurality of magnetic flux-producing formations which produce a first magnetic field. The stator carries a plurality of electrical winding coils which are energisable to generate a second magnetic field. The second rotor carries an arrangement of interpoles which modulate the first and second magnetic fields such that the modulated fields interact to transfer torque between the spools.

摘要： A synchronous motor which has a stator which includes a pair of permanent magnets of circular configuration surrounding a common axis and situated adjacent each other on opposite sides of a plane normal to the latter axis. Each of the permanent magnets has a series of N and S poles and the poles of one of the permanent magnets has a predetermined out-of-phase relationship with respect to the poles of the other of the magnets. These circular permanent magnets are coaxially surrounded by a pair of coils which are also situated adjacent each other on opposite sides of the latter plane, with a plate of magnetic material being situated in the plane between these coils to separate them from each other. The coils are respectively supplied with alternating currents which have with respect to each other the same out-of-phase relationship as the poles of the pair of permanent magnets, and the plate between the coils has an inner edge which is of a diameter substantially larger than that of the permanent magnets. A rotor is supported for free rotary movement around the above axis and includes a cylindrical wall which extends between the pair of permanent magnets, on the one hand, and the pair of coils and the plate therebetween, on the other hand. This cylindrical wall coaxially surrounds the above axis and is formed with a plurality of elongated axially extending openings circumferentially distributed uniformly around the above axis with the cylindrical wall of the rotor having between these openings elongated portions which extend parallel to the above axis. The number of poles of each of the permanent magnets is an even multiple of the number of elongated portions of the cylindrical wall of the rotor.

摘要： A bearingless split tooth flux-reversal motor (FRM) for use with a pump, such as a centrifugal blood pump. In some embodiments, the motor has a magnet-free rotor and a magnetic configuration wherein the force generation is independent of the rotor angle, allowing for simple radial force generation using stator-fixed currents. The motor torque can be generated using commutated two-phase currents.
