D C ELECTRIC MACHINE Russian patent published in 1999 - IPC

Abstract RU 2124800 C1

FIELD: electric machine engineering, design of nonsalient pole DC electric machines. SUBSTANCE: core of stator is truncated along generating line formed by pairs of parallel planes equal to number of poles so that formed sides make up angle with axis of compensation winding equal to 75-90 electrical degrees. EFFECT: diminished dimensions of machine, reduced waste of electrical sheet steel and copper in its structure by combination of compensation and series excitation windings, improved commutation. 1 dwg
