Motor-transformer consists of an alternating current transformer whose magnetic circuit is formed in a ring shape with the protrusions around the perimeter of the rings and the entire length of its circumference, and inside the magnetic core - of the ring spinning non-magnetic rotor, a cylindrical surface is recessed magnets on the same distance apart from each other as the projections on the yoke-ring. At the ends of a non-magnetic rotor, advocating the surface of the magnetic ring, secured non-magnetic disks and external non-magnetic ring. In all of their internal surfaces are recessed magnets with the same pitch as the projections on the yoke-ring. Step displacement between the projections is a point on the surface of the rotor as it rotates for one full period of the alternating current. On the yoke-ring in the spaces between the protrusions are wound the primary and secondary electrical windings. The technical result is to increase the torque.
DESCRIPTION OF THE INVENTION
The alleged invention relates to electric power.
The current transformer is used to convert AC power from one voltage to another.
It is proposed to perform magnetic circuit of the transformer in the form of a ring with protrusions around the perimeter of the rings and the entire length of its circumference. Inside the rotating magnetic rings the non-magnetic rotor, a cylindrical surface is recessed magnets at the same distance from each other as the projections on the yoke-ring.

At the ends of a non-magnetic rotor, advocating the surface of the magnetic ring, secured non-magnetic disks and external non-magnetic ring. In all of their internal surfaces are recessed magnets with the same pitch as the projections on the yoke-ring. Step displacement between the projections is a point on the surface of the rotor as it rotates for one full period of the alternating current.
where T - a step between the projections, D - the diameter of the rotor magnet and extending inner diameter lugs magnetic ring, N - number of AC cycles per second. In the magnetic circuit - the ring in the spaces between protrusions wound primary and secondary windings electrically. In the drawing, four fixing performance magnets are shown: direct and horseshoe. 1 - magnetic ring, 2 - rotating rotor. |
It is necessary to unwind nonmagnetic rotor with magnets built into it up to a speed at which one full period of the alternating current, one pole of the magnet is moved from a projection-magnetic ring to the other projection.
Then, for one half cycle AC magnetic ring protrusions ends attract the magnets of the rotor, while the other half-cycle of the AC they repel the same ends of the magnets. Then it is necessary to apply an alternating current to the primary winding. As a result, in the secondary winding obtain the desired AC voltage, and rotating the rotor with the magnets will produce a torque that can be used for various purposes.
CLAIM
Motor transformer comprising a magnetic circuit in the form of rings arranged around the perimeter of the rings protrusions, between which two coils are wound, primary, streamlined alternating current, and secondary - interacts with poles of alternating polarity of magnets mounted on the rotor, the distance between the poles which equal to the distance between the projections of the magnetic circuit, characterized in that the rotor is made with non-magnetic body and arranged inside the annular yoke and on its cylindrical surface embedded magnets and through the side nonmagnetic discs the rotor is attached outside the nonmagnetic ring with built in all their internal surface by magnets interacting with rotation protrusions magnetic bearing windings.
