FIELD: physics.
SUBSTANCE: invention relates to non-contact superconducting synchronous electric machines with combined excitation. Superconductive inductor electric machine with combined excitation includes stator with laminated core, fixed ring excitation windings, multiphase multi-pole armature winding, ferromagnetic shaft, on which ferromagnetic steel core of rotor with rotary projections (teeth) is installed. Unidirectional radially magnetized permanent magnets are located between ferromagnetic rotor projections. Magnetic shunts (interceptors) are installed on both end faces of the ferromagnetic core of the rotor. Non-magnetic slots are made on ferromagnetic rotary ledges.
EFFECT: technical result is increase in specific power and reliability.
