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

Abstract

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.

Simulation Model for Prediction of Transient Performance Characteristics of Single–Phase Shaded Pole Motor

“…Numerical models of shaded pole motors have been constructed in order to determine the magnetic flux density distribution at crosssection of shaded pole motor [14][15][16][17]. During recent years, the increasing numbers of simulation models of different types of the motors have been developed mainly aimed for the simulation of motor transient behaviour during start up to the steady-state operation regime [18][19][20][21][22][23][24][25]. These simulation models have proven themselves as reliable replacement of laboratory equipment necessary for recording motor transient operation and obtaining different motor parameters such as: starting currents and torque as well as motor starting time under no load or with different types of loads.…”
