FIELD: electricity.
SUBSTANCE: valve-inductor motors of proposed design comprise salient-pole symmetrical stator with concentrated windings made of ferromagnetic material, and bipolar symmetrical rotor made of ferromagnetic material, without windings and without permanent magnets. Slots of rotor in valve-inductor motor are filled with material, having diamagnetic properties, and neighbouring half-windings of stator are separated from each other with the help of T-shaped wedges made of materials having diamagnetic properties. Such structural design provides for the fact that in valve-inductor motor magnetic flows of scattering are practically unavailable since paths of these flows closing are barred with structural elements, having diamagnetic properties and being actually magnetic insulators. Reduced magnetic flows of scattering results in reduced coefficient of energy return, reduction of losses and increased motor torque.
EFFECT: reduced coefficient of energy return, reduced capacity of losses in valve-inductor motors and increased torque.
