The dynamics behavior of openloop electromagnetic torque control system, which is a part of doublefed asynchronous machine control system, is considered.The variant of torque control system with subordinated rotor and stator currents control systems under the frequency control is analyzed. The mathematical models of elements of electromagnetic torque system are shown. These models consist of the power part, current controllers and mode builder of asynchronous machine. During the description of electromagnetic torque control system the saturation of magnetic field was take into account. The main aim of simulation program is to investigate the influence of current control system performance on the dynamics of openloop electromagnetic torque control system. The simulation results of electromagnetic torque control system under different response speed of current control system are shown. It is shown that the decreasing of response speed the current controller begin to loss the ability to compensate the external disturbance, which is a motor speed. This fact results to disturb the coordinate system orientation, for which the electromagnetic torque controller is responsible. As a result, the dynamic responses of electromagnetic torque and speed control systems are decreased. Under given response speed of currents control system the quality levels of openloop electromagnetic torque control system depend of the value and rate of change the control and disturbance actions. The dynamics of torque control system are illustrated by means of transients graphics under the step control action and linear disturbance action. The main conclusions and recommendations for these investigations were formulated.
