A dual shaft integrated motor includes an inner rotor and an outer rotor that are independently rotatable and rotate in an identical pivotal direction. The inner rotor, an inner stator, an outer stator, and the outer rotor are sequentially arranged from a pivot in a radial direction. The inner stator and the outer stator interpose a non-magnetic body therebetween, the non-magnetic body being provided at a position contiguous with the inner stator and the outer stator along a circumferential direction centering on the pivot.

The disclosure relates to a rotor for an electrical machine having internal permanent magnets including a yoke consisting of a stack of sheets defining a plurality of recesses for receiving parallelepipedal permanent magnets, the recesses being surrounded by magnetically saturated external transverse isthmuses, by radial isthmuses, lateral isthmuses and oblique isthmuses, wherein the magnets are assembled in pairs of magnets magnetized in the same direction and perpendicular to the radial direction of the radial isthmuses arranged between the coupled magnets, the radial isthmuses having a thickness of less than 5% of the diameter of the rotor, and the perimeter of the cross section of the rotor is formed by a succession of curved profiles, between two consecutive pairs of magnets, and tangential linear profiles at the external transverse isthmuses. The disclosure also relates to the application of such a rotor for creating a motor, in particular a motor for a turbo compressor, or an electrical generator.

A transport apparatus including a housing, a drive mounted to the housing, and at least one transport arm connected to the drive where the drive includes at least one rotor having at least one salient pole of magnetic permeable material and disposed in an isolated environment, at least one stator having at least one salient pole with corresponding coil units and disposed outside the isolated environment, where the at least one salient pole of the at least one stator and the at least one salient pole of the rotor form a closed magnetic flux circuit between the at least one rotor and the at least one stator, and at least one seal configured to isolate the isolated environment where the at least one seal is integral to the at least one stator.

Electrical machines such as electromagnetic devices rely on the magnetic flux to create the forces required to move the component that transfers the work output of the device. Embodiment of the disclosure achieve this through a unique stator pole to rotor/actuator pole configuration that maximizes the magnetic flux flow across the air gap(s). This is achieved by tilting the air gap in more than one plane with respect to the rotation plane of the rotor.

On an AC permanent magnet switched reluctance motor stator seat, C-shaped or U-shaped excitation salient pole pairs or compound excitation salient pole pairs are set up in a balanced way. Excited by excitation current, the permanent magnet flux of compound excitation salient pole pair is imported into the main loop of excitation flux to form compound excitation magnetic potential. On the rotor support, permanent magnets are fixed at the same interval, and the magnetic polarity of neighboring permanent magnets on a same rotating surface is different. When the rotating shaft rotates, two magnet pole faces of each permanent magnet on rotor support will be dead against the two ports of each excitation salient pole pair on the stator, forming a closed magnetic loop with air gap.

A single phase permanent magnet motor includes a stator core, windings, and a permanent magnet rotor. The stator core includes an end portion and two spaced arm portions each including a connecting arm and a pole claw. Each pole claw has a long pole tip and a short pole tip, and forms a pole surface. The long pole tip of each pole claw corresponds to the short pole tip of the other pole claw with a slot opening formed there between. The slot opening causes the arc pole surface to be discontinued along a circumferential direction, and the arc pole surface is recessed inwardly to form a startup groove.

Methods, systems, and devices are disclosed for wind power generation. In one aspect, a wind power generator includes a support base; inductors positioned over the support base in a circular array; an annulus ring track fixed to the base support and providing a circular track around which the inductors are located; an annulus ring rotor placed on the annulus ring track and engaged to rollers in the circular track so that the annulus ring rotor can rotate relative to the an annulus ring track, in which the annulus ring rotor include separate magnets to move through the circular array of inductors to cause generation of electric currents; and a wind rotor assembly coupled to the annulus ring rotor and including wind-deflecting blades that rotate with the rotor and a hollow central interior for containing a wind vortex formed from deflecting wind by the blades to convert into the electric energy.

Disclosed is a doughnut type electromagnetic motor (100) having C-shaped stator windings (1), including C-shaped stator windings, a bearing shaft rod (2), permanent magnets (3), an adjustment circuit board (4), and a flat circular housing (5). The flat circular housing is configured to provide an ultrathin appearance structure for the motor. The permanent magnets serving as rotors are distributed along a second circle parallel to the flat circular housing, and are connected to the bearing shaft rod in the center of the motor by means of connectors, so as to form a permanent magnet rotor structure with the bearing shaft rod as a fulcrum. The C-shaped stator winding serving as a stator is arranged in a transverse direction of the permanent magnet rotor, and the permanent magnet rotor can pass through an inner ring of the C-shaped stator winding during rotating. The structure of the motor is simpler, the torque is increased, and the stator and the rotor can be separately processed and assembled, which makes the production more simplified and the practicability high.

A transport apparatus including a housing, a drive mounted to the housing, and at least one transport arm connected to the drive where the drive includes at least one rotor having at least one salient pole of magnetic permeable material and disposed in an isolated environment, at least one stator having at least one salient pole with corresponding coil units and disposed outside the isolated environment, where the at least one salient pole of the at least one stator and the at least one salient pole of the rotor form a closed magnetic flux circuit between the at least one rotor and the at least one stator, and at least one seal configured to isolate the isolated environment where the at least one seal is integral to the at least one stator.
