Abstract
Способ для испытания изделий из магнитомягких материалов, заключающийся в том, что в цепь генератора синусоидального напряжения включаются обмотка, нанесенная на испытуемый образец, переменный управляемый конденсатор, измеритель тока, цепь настраивается в резонанс напряжений, по току в обмотке испытуемого образца определяется напряженность магнитного поля в испытуемом образце, отличающийся тем, что с помощью измерителя тока фиксируются все значения намагничивающего тока, значение максимальной магнитной индукции определяется пропорционально среднему значению напряжения на обмотке испытуемого образца, резонанс определяется по совпадению фаз амплитудных значений напряжения последовательной цепи переменного управляемого конденсатора и обмотки испытуемого образца и тока в цепи, по вольтамперной характеристике последовательно включенных обмотки испытуемого образца и переменного управляемого конденсатора определяется форма петли гистерезиса испытуемого образца, соответствующая данному намагничивающему току, которая масштабируется пропорционально максимальному значению магнитной индукции, потери на перемагничивание определяются по площади петли гистерезиса, затем, изменяя амплитуду на выходе генератора синусоидального напряжения, таким же образом производят измерения петель гистерезиса для всех необходимых значений намагничивающего тока, а по пересечению предельной петли гистерезиса с вертикальной и горизонтальной осью определяют значения соответственно остаточной магнитной индукции и коэрцитивной силы испытуемого образца. A method for testing products from soft magnetic materials, which consists in the fact that a winding applied to the test sample, an alternating controlled capacitor, a current meter are included in the circuit of the sinusoidal voltage generator, the circuit is tuned to voltage resonance, the magnetic field strength is determined by the current in the winding of the test sample test sample, characterized in that with the help of a current meter all values of the magnetizing current are recorded, the value of the maximum magnetic induction is determined by the proportion As a function of the average value of the voltage across the winding of the test sample, the resonance is determined by the coincidence of the phases of the amplitude values of the voltage of the serial circuit of the variable controlled capacitor and the winding of the tested sample and the current in the circuit, the shape of the hysteresis loop of the tested sample is determined by the voltage-voltage characteristic of the series-connected windings of the tested sample and the variable controlled capacitor, corresponding to this magnetizing current, which scales proportionally to the maximum the value of the magnetic induction, the magnetization reversal losses are determined by the area of the hysteresis loop, then, changing the amplitude at the output of the sinusoidal voltage generator, the hysteresis loops are measured in the same way for all the necessary magnetizing current, and determined by the intersection of the limiting hysteresis loop with the vertical and horizontal axis values of the residual magnetic induction and the coercive force of the test sample, respectively.
