ELECTROMECHANICAL CONVERTER Russian patent published in 2007 - IPC H02K19/10 

FIELD: electrical engineering; low-speed drives, vehicle motor-wheels, elevator drive motors, generators, including windmill ones, as well as low- and medium-speed water-wheel generator,s synchronous condensers, and the like.

SUBSTANCE: proposed electromechanical converter has at least one stator-and-rotor pair in which stator has high-magnetic-permeability core whose butt-ends are attached to stator supporting ring and positioned in parallel with main magnetic flux. Multiphase winding conductors are disposed between these cores. Rotor is assembled of two coaxially disposed inductors, external and internal ones, made of high-magnetic-permeability material in the form of cylinders, they function as magnetic circuits and are mounted for rotation about stator and carry alternating-polarity poles disposed on circumference facing stator through working clearances and enclosing this stator. Polarity of poles disposed on internal and external inductors opposing one another is additive. Stator core number z and number of coil groups per phase d are correlated by equation p/d = k, where p is pole pair number; k = 1.5, 2, 2.5, 3, 3.5 ... is integer positive number or number differing from the latter by 0.5. When k is integer number, coil group windings of each phase are connected cumulatively. When k differs from integer number by 0.5, coil group windings are connected differentially in each phase. and 0.5 < z/(2 x p) < 2. In this case z/(2 x p) ≠ 1.

EFFECT: improved power characteristics, enhanced specific power output.
