The present disclosure relates to an actuator. The actuator includes at least two iron cores, each iron core including a pole extending in a first direction parallel to a direction of gravity; a permanent magnet disposed between the at least two iron cores so as to generate a magnetic field along a shape of a combination of the at least two iron cores arranged so as to be adjacent to each other in a direction not parallel to the first direction; and a winding wound around the pole of each of the at least two iron cores.

An electromagnetic generating transformer comprises one or more flux assembly having one or more magnetic field source having a positive pole and a negative pole and a magnetic field passing in a path between the positive pole and the negative pole and a conductor magnetically coupled with the one or more magnetic field source, the magnetic field source and the conductor being fixed relative to one another; a shunt is coupled with a motive source and configured to move the shunt into a primary position and a secondary position, wherein the magnitude of the magnetic field passing between the positive pole and the negative pole varies when the shunt is moved between the primary position and the secondary position.

A reluctance motor has salient teeth on both the stator and the rotor. The reluctance motor includes electrical coils that are usable to generate magnetic flux to drive rotation of the rotor. Concentrated coil windings are wound around each stator tooth. The electrical coils are arranged across all the stator teeth of the reluctance motor to enable the reluctance motor to be driven by alternating current. The electrical coils are arranged so that, when excited with alternating current, the number of magnetic half-poles is equal to the number of teeth on the rotor. The reluctance machine can operate using an inverter instead of an asymmetric bridge.

In a rotating electric machine, an axis direction width of a rotor core arranged at an end of a load side of the rotating shaft is set to be γ, an axis direction width of a rotor core arranged at an opposite side end of the load side is set to be ε, a distance from a support part at the load side to the rotor core at the load side is set to be α, and a distance from a support part at the opposite side of the load side to a rotor core at the opposite side of the load side is set to be β. In a case of α>β, γ≥ε is satisfied, and in a case of α<β, γ≤ε is satisfied. Thereby, the vibration of the rotor can be suppressed effectively.
