ELECTRICAL MACHINE Russian patent published in 2012 - IPC H02K16/02 H02K1/06 H02K17/00 

FIELD: electricity.

SUBSTANCE: in a proposed electrical machine, comprising a device for development of a magnetic field, where an inductor is represented by ferromagnetic cores with electric coils, and devices for conversion of one type of energy into another one, according to the invention, the device for development of the magnetic field is made as a separate unit in the form of a flange with concentric flanges on the wall made of non-magnetic and dielectric materials. In through radial slots made on flange collar rims, in a certain sequence, ferromagnetic cores are fixed with electric coils, which form pole pairs of the electrical machine. Stiffness of ferromagnetic cores fixation with electric coils in slots is ensured by a pressing cover, which is also made from non-magnetic and dielectric material. The device to convert one type of energy into another one consists of two rotors. One rotor is installed in the inner part of the device to develop a magnetic field and interacts with a so called main magnetic flux Φm and interacts with a so called magnetic leakage flux Φl.

EFFECT: higher efficiency of electrical machine operation due to using a magnetic leakage flux Φl in electric motors to develop a torque Mt, and in current generators - for production of electric energy.
