INVESTIGATION OF MAGNETIC CIRCUITS OF MEASURING TRANSDUCERS WITH A DISTRIBUTED LONGITUDINAL EXCITATION WINDING

The article examines the laws of distribution of magnetic voltage and magnetic flux in magnetic circuits of measuring transducers with distributed resistance parameters of long ferromagnetic rods and magnetic capacitance between them and a transverse distributed excitation winding using the example of a magnetic circuit of a new magnetically elastic force converter. It is established that in such magnetic circuits, the magnetic voltage changes its sign when passing through the section of the magnetic neutral, and the magnetic flux in the magnetic neutral has a maximum value, with a fixed value of the length of the distributed excitation winding, the nonlinearity of the change in the absolute value of the magnetic voltage, and the rate of decrease of the magnetic flux from this section towards the end parts of the magnetic circuit depends on the value the attenuation coefficient of the magnetic flux: the greater the value of this coefficient, the greater the degree of nonlinearity of the absolute value of the magnetic voltage and the rate of change of the magnetic flux along the length of the magnetic circuit. It is shown that in such magnetic circuits, at a fixed value of the magnetic flux attenuation coefficient, the nonlinearity of the change in the absolute value of the magnetic voltage and the rate of decrease of the magnetic flux from this section towards the end parts of the magnetic circuit at a rate depending on the value of the length of the distributed excitation winding: the greater the value of the length of the distributed excitation winding, the less the degree of nonlinearity of the absolute value the magnetic voltage and the rate of change of the magnetic flux along the length of the magnetic circuit.
