The Simulation and Experimental Results of Dynamic Behaviour of Torque Motor Having Permanent Magnets

The application, construction, and principle of operation of the torque motor having permanent magnets are presented first. Since dynamic behaviour of a servohydraulic system is, to a large extent, determined by dynamic behaviour of the applied torque motor, an analysis of motor’s dynamic behaviour is carried out and its dynamic transfer characteristic is determined. Finally, the simulation and experimental results of dynamic behaviour of the torque motor are presented.
