摘要： In an armature, a busbar unit includes at least first-, second-, and third-phase busbars electrically connected to respective first-, second-, and third-phase armature windings. The first-phase busbar serves as a lowermost busbar in the axial direction, the second-phase busbar serves as an intermediate busbar stacked over the lowermost busbar in the axial direction, and the third-phase busbar serves as an uppermost busbar stacked over the intermediate busbar in the axial direction. A resin member of the busbar unit covers the lowermost busbar, intermediate busbar, and uppermost busbar stacked in the axial direction, so that the lowermost busbar, intermediate busbar, and uppermost busbar are integrated to constitute a busbar stack. A protrusion member is mounted to the intermediate busbar and protruding radially outward from the intermediate busbar. At least part of the protrusion member is located to be nonoverlapped with the uppermost busbar and the lowermost busbar.

摘要： A power generating device comprises a magnetic core, an induction coil assembly, a first housing, a conductive plate, and a second housing. The induction coil assembly is coupled with the magnetic core, and the magnetic core and the induction assembly are configured in the accommodating space of the first housing. The conductive plate is attracted to the magnetic core. The second housing is configured above the conductive plate. When the second housing receives an external force along an extending direction of the magnetic core, a distance change between the conductive plate and the magnetic core causes a variation of magnetic flux. The induction coil assembly generates a current by sensing the magnetic flux variation.

摘要： A coaxial electromagnetic apparatus formed of at least one magnetic disk and at least one coil disk synchronously and relatively movable and staggered at intervals. The magnetic disk and the coil disk are respectively provided with at least one power-driven module and at least one power generation module. The power-driven modules are provided at the outermost diameters of the magnetic disk and the coil disk. The power generation modules are provided at the innermost diameters of the magnetic disk and the coil disk. A rotation speed of the magnetic disk is increased due to torque amplification and good magnetic current management of the power-driven modules, thereby achieving low power consumption and large thrust of the power-driven modules. The power generation modules generate high cutting frequency to increase power generated and meet the requirement for supplying power to the power-driven modules, thereby achieving autonomous power generation and a self-propelled motor.

摘要： An interactive electromagnetic apparatus, which includes an acting magnet assembly, a conducting magnet assembly parallel with the acting magnet assembly, an induction coil assembly arranged between the acting magnet assembly and the conducting magnet assembly, and an induction switch module, in which the acting magnet assembly includes at least two magnets arranged to space from each other. These magnets have magnetic poles face the induction coil assembly. The adjacent ones of the magnets are arranged to have opposite magnetic poles face each other. The conducting magnet assembly includes at least two magnets arranged to space from each other. These magnets have two ends having magnetic poles parallel with a moving direction. As such, the induction coil assembly generates a reverse magnetic resistance force at only one end thereof.

摘要： An electrical system including a linear motor in which energized forcer and thruster coils are used for the field and armature elements. In accordance with exemplary embodiments, one or more thruster coils may be provided on a shaft with opposing single or multiple fixed forcer coils. Using coils as the electromagnets for forcer and thruster coils advantageously provides necessary power while also minimizing system weight and decreases in magnetism typically encountered with permanent magnets with rising temperature, resulting in higher and more controllable magnetic forces over varying temperatures. Ferrous elements, such as a ferrous system housing and/or open ferrous containers for the thruster coils may be further included to advantageously focus the magnetic forces. Additionally, multiple forcer and thruster coils may be disposed in various arrangements along the shaft. Exemplary applications include use of such a system for controlling oscillations of a poppet valve in an internal combustion engine.

摘要： An electromagnetic reciprocating fluid apparatus includes a magnetic circuit device in which magnetic pole members project inward from an annular magnetic circuit member so as to oppose each other. The magnetic pole members and the annular magnetic circuit member have a uniform thickness. First and second additional annular magnetic circuit members are set on both sides of the annular magnetic circuit member to constitute a part of the magnetic circuit device, thereby minimizing the increase in magnetic reluctance due to magnetic flux concentration at the joints between the magnetic pole members and the annular magnetic circuit member.

摘要： A linear electrodynamic system for conversion of mechanical motion into electrical power or conversion of electrical power into mechanical motion allows for advantageous mass and size reductions. Magnet volume is increased through use of non-annular shaped magnets affixed to stator poles. Mover sections complementary in shape to the non-annular magnets. The mover, stator and associated windings used have reduced mass and size resulting in overall mass and size reductions of the innovative linear electrodynamic system compared with conventional linear electrodynamic systems of similar performance capability.
