Description
Известны устройства дл определени магнитных свойств магнитотвердых материалов, содержащие трехстержневой магнитопровод, на крайних стержн х которого помещены намагничивающие обмотки, а на среднем стержне - измерительна обмотка. Один из крайннх стержней имеет воздушный зазор дл установки в нем испыт смого образца , а в воздущном зазоре среднего стержн пол ещаетс ротор.Devices are known for determining the magnetic properties of magnetically hard materials, containing a three-core magnetic conductor, on the extreme rods of which magnetizing windings are placed, and a measuring winding is placed on the middle rod. One of the extreme rods has an air gap for mounting a test sample in it, and a rotor is still in the middle air gap.
Отличие предлагаемого устройства заключаетс в том, что дл повыщени точности измерений ротор выполнен из двух сердечников с вно выраженными полюсами, закрепленных на одной оси. Сердечники ротора сдвинуты один относительно другого на 90° и помещаютс в зазорах параллельных ветвей среднего стержн .The difference of the proposed device lies in the fact that in order to increase the measurement accuracy the rotor is made of two cores with pronounced poles fixed on one axis. The rotor cores are shifted by 90 ° relative to each other and placed in the gaps of the parallel branches of the middle stem.
Pia чертеже показана иринципиальна схема устройства с выделенным средним стержнем.The pia drawing shows an irincipital diagram of the device with a highlighted middle rod.
На крайних стержн х магнптопровода расположены намагничивающие обмотки W п . Магнитные потоки Ф1 и Ф2, создавае.мые токами /I и /2, проход щими по обмоткам W и W-2, замыкаютс через средний стержень и направлены навстречу друг . Величина тока /i подбираетс с таким расчетом, чтобы суммарный магнитный ноток через средний стержень был равен нулю, т. е. Ф + Ф2 0, откуда cDi -Ф2. Средний стержень магнитопровода состоит из двух параллельных ветвей, в зазорах которых расположен ротор Р. Дл повыщени точности измерений ротор Р выполнен из двух сердечников PI и PZ, сдвинутых один относительно другого на 90°. На среднем стержне помещена измерительна обмотка , концы которой подключаютс к входным зажимам усилител У, присоединенного к ламповому вольтметру ЛВ. Образец испытуемого материала ОМ помещаетс в зазоре одного из крайних стержней.On the extreme rods of the magnetic pipeline are magnetizing windings W p. The magnetic fluxes F1 and F2, created by the currents / I and / 2 passing through the windings W and W-2, are closed through the middle rod and directed towards each other. The magnitude of the current / i is chosen so that the total magnetic note through the middle rod is zero, i.e. F + F2 0, hence cDi -F2. The middle core of the magnetic circuit consists of two parallel branches, in the gaps of which the rotor P is located. A measuring winding is placed on the middle rod, the ends of which are connected to the input terminals of the amplifier V connected to the LV lamp voltmeter. A sample of the OM material being tested is placed in the gap of one of the outermost rods.
