    Abstract: An electric submersible pump (ESP) that has a motor section for driving the ESP. The motor section has a stator has an inner surface, winding channels disposed axially therein and windings disposed in the winding channels to generate an electromagnetic field when power is supplied to the ESP. The motor section also has a rotor rotatably disposed in the stator. The rotor has permanent magnets or induction windings disposed therein that are responsive to the electromagnetic field to facilitate rotation of the rotor relative to the stator. The motor section also includes a manipulated air gap disposed between the rotor and the stator that the electromagnetic field crosses. The manipulated air gap provides a desired constant radially directed load on the rotor to stabilize the rotor when instability of the motor section occurs. A method of designing and constructing the ESP disclosed herein. To design and construct the ESP, a desired constant radially directed load is determined for an electric submersible pump (ESP) to stabilize the ESP when instability of an electromagnetic field of the ESP occurs. The air gap is manipulated to achieve the desired constant radially directed load or the design of a stator of the ESP is manipulated to achieve the desired constant radially directed load. The ESP can then be constructed.

    Abstract: A planar drive system comprises a stator and a rotor. The stator comprises a plurality of stator conductors. The rotor comprises a magnet device comprising at least one rotor magnet. The stator is configured to energize the stator conductors. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device of the rotor in order to drive the rotor. The stator is configured to carry out the energizing of the stator conductors by a current control based on a pulse-width modulation. Due to the current control, a ripple current in energized stator conductors of the stator and thereby an alternating magnetic field can be generated. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field.

    Abstract: An inner rotor includes a rotor body, a polar anisotropic magnet, and magnetic bodies. The rotor body rotates about a rotation axis. The polar anisotropic magnet is located at an outer peripheral surface of the rotor body and has magnetic poles arranged in a circumferential direction centered on the rotation axis. The magnetic bodies are arranged on an outer peripheral surface of the polar anisotropic magnet at positions corresponding to the magnetic poles.

    Abstract: A rotating electrical machine capable of obtaining a higher torque while limiting the amount of permanent magnets used. A magnetic pole of a rotor includes an auxiliary magnet embedded in a rotor core and at least one main magnet arranged on an outer circumferential side than the auxiliary magnet of the rotor. In each magnetic pole, the distance from an end of the main magnet, the end facing the auxiliary magnet, to the auxiliary magnet facing the main magnet is shorter than the length of the main magnet in the radial direction. In a cross-section orthogonal to the rotation axis of the rotating electrical machine, the main magnets of each magnetic pole are arranged so as to be asymmetrical about a virtual line passing the rotation axis and axisymmetrically dividing the auxiliary magnet.

    Abstract: An electromechanical kinetic motor including a frame, a stator, a rotor, a power source, and an electric load. The stator is connected to the frame and includes a coil. The rotor is rotatably connected to the frame and includes a magnet. The power source is electrically connected to the coil. The electric load is connected to the coil and configured to extract power from the coil. The coil generates an electromagnetic field in response to electricity provided by the power source. The rotor is configured to rotate the magnet through the magnetic field generated by the coil. An electric current is induced in the coil by the rotation of the magnet through the electromagnetic field generated by the coil.
