1one

Изобретение относдтс к приборостроению , в частности к магнитным опорам.The invention relates to instrument making, in particular to magnetic bearings.

По осноикллу авт. св. Мз 483578 известна магнитна опора, совмещенна с датчиком угла, содержаща ротор с вно выраженными пошосами и статор с сигнапьными обмотками и обмотками воз ждени , |}аспо оженными в пазах статсфа с щел ми .On Osnoycl auth. St. Ms 483578 is a known magnetic support, combined with an angle sensor, containing a rotor with pronounced outcrops and a stator with signal windings and excitation windings,} suspended in the slots with slots.

Однако устройство имеет недостаточ- to ную подъемную сипу и жесткость подвеса.However, the device has insufficient lifting vulture and suspension rigidity.

Цепь изобретени - повышение пере грузочиой способности и увеличение жесткости поовеса. .The chain of the invention is to increase the overload capacity and increase the rigidity of the weight. .

Указанна цепь достигаетс тем, что is в магнитной опоре, совмещений с датчиком угла, в ше в. пазов статора введены магнитные шунты из магнитом гкого материала.This circuit is achieved by the fact that is in a magnetic support, alignments with an angle sensor, in above. Magnetic shunts made of magnet material are inserted into the stator slots.

На чертеже изображена магиитнш онора совмещенна с датчиком углаThe drawing depicts an onor magnetization combined with an angle sensor.

Устройство содержит ротор 1 с юсо выраженными полюсами 2 и статор 3. с сигнальными обмотками 4 и о& откамиThe device comprises a rotor 1 with pronounced poles 2 and a stator 3. with signal windings 4 and o & otkami

5 возбуждени , расположенными в па зах 6 статора со щел ми 7, в щели пазов статора введены магнитные шунты 8 из магнитом гкого материала, магнитна проницаемость которого больше, а магнитна индукци насыщени меньше, чем у материала статора.5 excitations located in the stator pins 6 with slots 7, magnetic shunts 8 made of magnetically soft material are introduced into the slots of the stator slots, the magnetic permeability of which is greater and the magnetic induction of saturation is less than that of the stator material.

Магнитна стора, совмещенна с датчиком угла, работает следукнним образом.The magnet stor combined with the angle sensor works in the following way.

Claims

When the rotor 1 is rotated with its exponentially; - by the poles 2, a signal is generated in the signal windings 4 proportional to the angle of rotation of the rotor. At a laugh As the rotor increases in the direction of increasing the gap, the magnetic flux of the stator 3 with the side: - through the rotor, creating centering from the dust. Simultaneously from the opposite side, the working gap decreases, the magnetic flux in the gap decreases, and with a certain gap it becomes equal and less magnetic flux saturations fermenting shunt 8. Since magnetic shunt 8 is made of a material with greater magnetic permeability than that of stator 3, almost the entire magnetic flux is closed through the magnetic shunt. This leads to a change in the magnetic flux in the working gap, a decrease in the force acting on the rotor from the side of the stator with a reduced working gap, and consequently, an increase in the overload capacity of the suspension rigidity. Magnetic support combined with angle sensor according to the author. St. No. 483578, characterized in that, with a chain of overload capacity and an increase in the rigidity of the suspension, magnetic shunts of magnetically flexible material are inserted into the slots of the stator slots.
