FIELD: electricity.
SUBSTANCE: invention refers to peculiar features of the design of non-contact synchronous magnetic-electric machines and 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 synchronous magnetoelectric machine with modulated magnetomotive force of armature includes stator the armature core of which consists of insulated electrotechnical steel sheets with high magnetic permeability and has express poles with coil m-phase armature winding, each coil of which is arranged on the appropriate express pole of armature, one per a pole, as well as rotor which contains inductor with express poles with alternating polarity, which are symmetrically distributed along cylindrical surface and excited with constant magnets. At that, certain ratios are fulfilled between the number of express armature poles, number of phases of m-phase armature winding, number of express poles of armature in phase and number of express poles of inductor.
EFFECT: high energy properties, high specific torque moment on the shaft, reducing pulsations of torque moment, vibration and noise of non-contact synchronous magnetoelectric machine owing to its multi-phase design with modulated magnetomotive armature force.
