Abstract
Устройство для измерения динамического распределения магнитной восприимчивости ферромагнетика, выполненного в виде кольца, краем помещенного в магнитный зазор электромагнита с регулируемым в широких пределах постоянным магнитным полем и вращающегося от синхронного электродвигателя, подключенного к многофазному генератору с регулируемой частотой, а также включающее магнитный датчик с обмоткой, образующей с параллельно подключенным к ней подстраиваемым конденсатором колебательный контур высокочастотного генератора, выходом подключенного к первому входу смесителя, ко второму входу которого подсоединен выход опорного генератора перестраиваемой частоты, выход смесителя связан с первым информационным входом блока вычисления и индикации, на второй, третий и четвертый информационные входы которого подключены соответственно выход одной из фаз многофазного генератора, регулируемого источника постоянного тока и датчика угла перемещения магнитного датчика относительно боковой поверхности ферромагнитного кольца в пределах длины магнитного зазора электромагнита, причем указанное перемещение осуществлено с помощью шагового привода, связанного механически с датчиком угла и управляемого от блока вычисления и индикации, который также программно управляет частотой многофазного генератора и регулируемого источника постоянного тока, подключенного к обмотке электромагнита. A device for measuring the dynamic distribution of the magnetic susceptibility of a ferromagnet, made in the form of a ring, an edge of an electromagnet placed in the magnetic gap with a widely adjustable constant magnetic field and rotating from a synchronous motor connected to a multiphase generator with an adjustable frequency, and also including a magnetic sensor with a winding, forming with a parallel adjustable capacitor connected to it, an oscillatory circuit of a high-frequency generator, output connected to the first input of the mixer, to the second input of which the output of the tunable frequency reference oscillator is connected, the output of the mixer is connected to the first information input of the calculation and indication unit, the second, third and fourth information inputs of which are connected respectively to the output of one of the phases of the multiphase generator, an adjustable constant source current and the angle sensor of the magnetic sensor relative to the side surface of the ferromagnetic ring within the length of the magnetic gap of the electromagnet, p When in use, said movement performed by a stepping drive, mechanically connected with the sensor and controlled by the angle calculation unit and display program which also controls the frequency of the polyphase generator and the adjustable constant current source connected to the coil of the electromagnet.
