Axial Asynchronous Motor With A Rotor Two-section Cone-cylindrical Magnetic Circuit

Abstract

The possibilities of improving the axial asynchronous engine by formation of two-section magnetic circuit and rotor winding with radial conical surfaces of teeth, tangential displacement of the core parts of sections and intermediate short-circuiting rings are shown. The displacement of the core sections of winding within of the toothed division limits is equivalent to the slots slope of machines with a cylindrical gap and weakens the electromotive forces and additional moments from the higher harmonics of the magnetic field. The condition for sectional components of the rotor currents compensation from the magnetic field toothed harmonics is obtained.
