FIELD: electrical engineering.
SUBSTANCE: electric reducer machine with a polar gear inducer contains a stator (its armature core made laminated and having clearly express poles on the inner surface whereof elementary cogs are arranged), the armature m-phase coil winding and a rotor containing an inducer with clearly express gear poles, symmetrically distributed along the cylindrical surface, with coil excitation winding placed on the poles. Electrical connection between the inducer excitation winding and the voltage source is effected via brushes and contact rings of the brush contact unit. Subject to definite ratios between number of clearly express armature poles, number of elementary cogs on a clearly express armature pole, number of clearly express armature poles per phase, total number of armature cogs, number of the inducer gear poles, total number of the inducer cogs, number of elementary cogs per inducer gear pole and number of phases in the m-phase armature winding of the electric reducer machine with a polar gear inducer the technical effect is achieved.
EFFECT: provision for high power and operational indicators, high specific rotation torque on shaft and high electromagnetic reduction of rotation speed in electric motor mode, high specific power at high frequencies of EMF in electric generator mode.
