Abstract

Устройство для измерения угловой скорости вращения магнитного поля, содержащее вращающийся ферромагнитный ротор и неподвижный магнитопроводящий статор, отличающееся тем, что ферромагнитный ротор выполнен в форме цилиндра с осью вращения, в средней части которого осесимметрично размещена бесконтактно обмотка подмагничивания ротора, связанная с регулируемым источником постоянного тока, измеряемым амперметром, магнитопроводящий статор выполнен в форме двух соосно с ротором расположенных цилиндров, на которых выполнены соответственно две обмотки вблизи магнитных полюсов ротора в виде тороидов, часть каждого из витков которых расположена в цилиндрических магнитных зазорах между ротором и статором, и эти части витков расположены на некотором расстоянии от статора внутри магнитных зазоров, например, по их середине или ближе к цилиндрической поверхности ротора, при этом ротор приводится во вращательное движение от синхронного двигателя переменного тока с регулируемой частотой вращения, измеряемой частотомером, а возникающая в статорной обмотке э.д.с. индукции измеряется регистрирующим вольтметром.A device for measuring the angular velocity of rotation of a magnetic field, containing a rotating ferromagnetic rotor and a stationary magnetically conductive stator, characterized in that the ferromagnetic rotor is made in the form of a cylinder with an axis of rotation, in the middle part of which is contactless the magnetizing winding of the rotor, connected with an adjustable constant current source, measured by an ammeter, the magnetically conductive stator is made in the form of two cylinders coaxial with the rotor, on which are made respectively two windings near the magnetic poles of the rotor in the form of toroids, part of each of which turns is located in cylindrical magnetic gaps between the rotor and the stator, and these parts of the turns are located at some distance from the stator inside the magnetic gaps, for example, along their middle or closer to the cylindrical surface the rotor, while the rotor is driven in rotational motion from a synchronous alternating current motor with an adjustable speed, as measured by a frequency meter, and the emf arising in the stator winding induction is measured by a recording voltmeter.
