AXIAL INDUCTOR ELECTRIC MACHINE WITH ELECTROMAGNET EXCITATION Russian patent published in 2014 - IPC H02K19/20 H02K19/24 H02K7/18 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering, and namely to electric machines and is referred to design of axial inductor electric machines. The suggested axial inductor electric machine with electromagnet excitation contains the stator housing, stator magnet packs, excitation windings, windings of alternating electromotive force, the rotor and rotor magnet packs. According to the invention a cylindrical turbine rotated in a flow of gas or another medium as the rotor shaft is equipped with three geared magnet packs place axially to the stator windings at the outer diameter of the turbine shaft and are shifted per ⅓ of the geared section and without open magnetic-air gap with the stator windings they form the three-phase system of a reversible electric machine. In motor operation one type of control voltage is supplied to the windings of alternating electromotive force in the form of sequential rectangular electrical pulses which duration defines frequency of the rotor shaft rotation.

EFFECT: in motor mode one type of control voltage is used, in generator mode electric energy can be generated using flows of different media and implementing the function of a starter-generator with high shaft torque in a wide range of preset rates, with high mechanic endurance and high degree of protection.
