Description

расположен кольцевой посто нный магпит 18, намагнпченный в осевом направлении. Зубчатые поверхности неподвижных и вращающихс  дисков образуют воздушные зазоры 19-22. При подаче питани  в обмотки статора система управлени  воздействует на рабочее поле двигател , устанавлива  ротор в среднем осевом положении между пакетами статора. При этом пассивпа  радиальна  стабилизаци  осуществл етс  магнитным полем посто нного магнита с помощью зубчатых поверхностей дисков. Отклонение ротора в радиальном направлении, а также его перекос вызывают изменение магнитной проводимости в зазорах радиального центрирующего устройства, что вызывает по вление стабилизирующих магнитных сил. При аксиальном смещении ротора немагнитное кольцо 17 среднего диска преп тствует перераспределению магнитных потоков в зазорах 19, 21 и 20, 22, расположенных последовательно по пути магнитного потока. Вследствие этого осева  дестабилизаци  значительно ослабл етс , что повышает эффективность работы осевой системы стабилизации. Применение данной конструкции позвол ет без увеличени  числа каналов регулировани  обеспечить эффективную работу системы комбинированного магнитного подвеса, снижа  потери в подвесе и увеличива  КПД электрической машины.there is an annular permanent magpe 18 magnetized axially. The serrated surfaces of the fixed and rotating discs form air gaps 19-22. When power is supplied to the stator windings, the control system acts on the engine's working field, setting the rotor in the middle axial position between the stator packages. In this case, the passivp radial stabilization is carried out by the magnetic field of the permanent magnet with the help of the toothed surfaces of the disks. The deviation of the rotor in the radial direction, as well as its bias, causes a change in the magnetic conductivity in the gaps of the radial centering device, which causes the appearance of stabilizing magnetic forces. With an axial displacement of the rotor, the non-magnetic ring 17 of the middle disk prevents the redistribution of magnetic fluxes in the gaps 19, 21 and 20, 22 arranged in series along the path of the magnetic flux. As a result, axial destabilization is significantly weakened, which increases the efficiency of the axial stabilization system. The use of this design allows, without increasing the number of control channels, to ensure the effective operation of the combined magnetic suspension system, reducing the losses in the suspension and increasing the efficiency of the electric machine.
