FIELD: electricity.
SUBSTANCE: invention can be used in automation systems as traction controlled and non-controlled electric drives, as wind generators, hydraulic generators, high-frequency electric generators, multi-phase synchronous electric motors and electric generators of frequency converters, as well as multi-phase power sources of electric current. The proposed non-contact magnetoelectric machine with modulated magnetomotive force of armature includes stator the armature core of which consists of isolated electrotechnical steel sheets with high magnetic permeability and has salient poles with coil w-phase armature winding, each coil of which is arranged on the appropriate salient pole of armature, one per a pole, as well as rotor which contains inductor with salient poles with alternating polarity, which are symmetrically distributed along cylindrical surface and excited with constant magnets. At that, there are certain ratios between the number of salient armature poles, number of phases of w-phase armature winding, number of salient poles of armature in phase and number of salient poles of inductor.
EFFECT: high energy data, high specific torque moment on the shaft in electric motor mode and high specific power in electric generator mode at reduction of torque moment pulsations, vibration and noise of non-contact magnetoelectric machine owing to its multi-phase design with modulated magnetomotive force of armature.
