Abstract:
The simulation analysis of the transient response performance of a single cage machine has been conducted in MATLAB/Simulink environment. Having obtained the mathematical model of an induction motor based on Park's transformation in d-q reference frame, a Simulink model was developed to investigate the behaviour of the motor under no load, half load and full load conditions. The Simulation results have shown that increasing load torque affects the transient and steady state efficiency of induction machine. Generally, the transient behaviour of the single cage motor under no load is that its rise time (or response time) to input signal was 0.81 s, settling time (time to settle or reached steady state) was 1.09 s, and the steady-state speed was 1500 rpm. At half loading, its rise time was 1.23 s, settling time was 1.58 s, and it steady-state speed was 1463 rpm. At full load, the rise time in this case was 2.18 s, the settling time was 2.98 s, and the speed at steady-state was 1415 rpm.
