Description

tt

Изобретение относитс  к электрическим машинам, а именно к магнитным системам роторов электрических машин с возбуждением от посто нных магнитов.The invention relates to electric machines, in particular to magnetic systems of rotors of electric machines with excitation from permanent magnets.

В насто щее врем  в магнитных системах роторов электрических машин широко используютс  посто нные магниты .Nowadays, permanent magnets are widely used in magnetic systems of electric machine rotors.

Известны конструкциироторов, в которых за счет концентрации магнитного потока полюсными сегментами возMoxwo получить индукцию в зазоре магнита выше остаточной индукции полюсных магнитов. С увеличением числа полюсов такого ротора увеличиваетс  суммарный рабочий поток в зазоре электрической машины, что позвол ет повысить мощность электрической машины , уменьшить расход меди. Известны и широко примен ютс  магнитные системы роторов 12-полюсные и более.Known constructions of rotors, in which due to the concentration of the magnetic flux by the pole segments of the Maxwo, induction in the magnet gap is higher than the residual induction of the pole magnets. With an increase in the number of poles of such a rotor, the total working flow in the gap of the electric machine increases, which allows increasing the power of the electric machine and reducing the consumption of copper. Magnetic systems of rotors 12-pole and more are known and widely used.

Электродвигатели с такими магнитными системами начинают примен ть в бесконтактном приводе flj.Electric motors with such magnetic systems are beginning to be used in the flj contactless drive.

Известны устройства, которые обеспечивают поддержание любого угла между вектором пол  статора и ротора .Devices are known that maintain any angle between the stator and rotor floor vector.

Применение таких устройств позвол ет работать в точке максимума электромагнитного момента (точка выпадени  из синхронизации дл  обычных синхронных электродвигателей без систем управлени ) и, следовательно, максимально использовать двигатель.The use of such devices allows operation at the point of maximum of the electromagnetic moment (point of fallout from synchronization for conventional synchronous motors without control systems) and, therefore, makes the most of the motor.
