A rotary electrical machine comprises: a mechanical motor/generator assembly, and optional electronics. The mechanical motor/generator assembly comprises: a core assembly, and an armature assembly. The core assembly comprises two magnet assemblies, which are positioned to define an air gap therebetween and produce time invariant magnetic fields in the air gap. The armature assembly comprises: an armature, and one or more conductors that are mounted to the armature and positioned in the air gap. Either the core assembly or the armature assembly may be mounted to a rotating element, while the other is mounted to a stationary element. During operation as a motor, electrical current flows in alternating directions in the one or more conductors, to produce torque on the armature and rotating element. During operation as a generator, electrical current is produced in the one or more conductors when torque is applied to the rotating element and the armature.

A power apparatus, power assembly, energy assembly or energy apparatus that stores and disperses energy, the power assembly including: (1) a first and second energy object that experiences movement so as to store kinetic energy in the energy object, the energy object including a magnet assembly through which electrons are driven resulting in electric output from the magnet assembly, and the electric output dependent on experienced EMF (electro-motive force) that is experienced by the magnet assembly. The power assembly can include a switch assembly adapted to perform switching to switch between a first arrangement in which the first positive output is connected to the second positive output, and a second arrangement in which the first positive output is connected to the first negative output, and such second arrangement provides increased energy output relative to the first arrangement. A flip assembly can be provided that performs flipping of output energy.

A synchronous reluctance motor includes: an annular stator; and a rotor disposed radially inside the stator. The stator includes an annular stator core having in its inner peripheral portion a plurality of slots located at intervals in a circumferential direction of the stator, and slot coils accommodated in the slots. The slot coils are formed by a wire having a quadrilateral section and are wound in the slots by distributed winding.

The purpose of the present invention is to provide an electric generator which allows the magnitude of mutual magnetic action between a rotor and an armature to be self-adjusted in the electric generator against a fluctuation in a motive power or a fluctuation in an electric load, such that the magnitude of an induced electromotive force is controlled to compensate, with voltage variation, for amounts of the fluctuation in the motive power and the fluctuation in the electric load and to induce electricity with a uniform frequency from the electric generator, while stabilizing the prime mover or load devices, and parts optimized for the same. To this end, the present invention has an iron-piece structure in which the rotor and the armature of the electric generator mutually correspond to each other in a concave-convex structure, and the present invention is configured to be able to control the magnitude of the induced electromotive force, as the armature moves in the axial direction in response to a change in the rotation speed, output voltage, or frequency of the electric generator and, thereby, variably controls a mutually corresponding length of the concave-convex structure.

A rotor of a synchronous motor includes a rotor core that includes magnet insertion holes and a plurality of slits formed on an outer peripheral side of the magnet insertion holes, and permanent magnets embedded in the magnet insertion holes. Magnetic-path forming slits are formed at intervals in a direction along a side of the permanent magnet. Magnetic paths are formed between the magnetic-path forming slits and at portions on the outside of the magnetic-path forming slits on the outermost side. An adjusting slit is formed between a predetermined magnetic-path forming slit and the permanent magnet such that a difference between quantities of magnetic flux passing through the magnetic paths adjacent to each other for widths in a direction intersecting an orientation of a magnetic pole of the permanent magnet is small.
