FIELD: electricity.
SUBSTANCE: electric reducing machine with electromagnetic excitation contains stator with salient poles on the inner surface of which elementary teeth are executed. The stator's m-phase concentrated winding of armature is comprised of coils, each coil wraps corresponding armature pole. The machine also contains ferromagnetic toothed rotor without windings with odd and even inductor cores the number of which is not less than two. Even inductor cores are shifted relative to odd cores in tangential direction by half of inductor tooth mark, between odd and even inductor cores the ring-shaped inductor exciting coils are located. Electric connection of inductor exciting winding with constant (rectified) voltage source is implemented via contact rings and brushes. In this machine, certain relations between armature poles number, elementary teeth number on armature pole, number of teeth on each inductor core and armature winding phases number of electric reducing machine with electromagnetic excitation are observed.
EFFECT: achievement of high power and operational indicators, high specific rotation torque on shaft and high electromagnetic reduction of rotation speed in electric motor mode and high specific power at high frequencies of EMF in electric generator mode.
