Simulation model of elastomagnetic sensors

An article says about the basic magnetic features of ferromagnetic material, which need to be taken to the consideration when designing model of elastomagnetic sensor. Mentioned is an intelligent calculator, which is used for calculation of change of sensor permeability in cubic grate in dependence of the lay of vectors of magnetostriction and external field. In the article, the sensor model in program PSPICE is described. Model in program PSPICE simulates a real hysteresis loop of sensor, his loses, his dependency from the frequency and the entry signal. Realized is by passive elements and controlled current sources the way it could simulates real entry signal and also the shape of the hysteresis loop. In the conclusion of the article, the hysteresis loop of real sensor of a torque is showed. The basic requirements for the sensor model were simplicity, accuracy, comprehensibility, open system and further utility for similar types of sensors.
