“…The simplest method used for controlling the speed of a slip ring induction motor is to convert a small amount of power into outer side impedance, as a result the motor current and total energy consumption are reduced (Ameen, 2011a). The power factor and rotor current distortion have been improved by third harmonic current injection in the rotor side of static rotor resistance variation, and the THD of rotor current has been reduced from 25% to 3% (Ameen, 2011b). (Kumar et al, 2017) presented the speed control of wound rotor induction motor by static rotor resistance variation using MATLAB/Simulink for rotor chopper resistance and slip power recovery induction motor.…”

This paper examines the impact of harmonics generated by the power semiconductor devices in the rotor circuit of a Softly Rotor Resistance Variation Induction Motor Drive System (SRRVIMDS) operating under voltage asymmetry. The study evaluates the components of rotor currents, electromagnetic torque, and stator winding currents based on a detailed mathematical circuit model configuration. The analysis also investigates the stator winding distortion currents produced by electromagnetic induction in the stator windings due to the harmonic components of the rotor current. The paper provides relationships for estimating all harmonic order frequencies of the stator currents, rotor currents, and torque as a function of the stator frequency and rotor speed. The results show that the investigated currents have sufficient accuracy, except at a slip of one-sixth, where notable differences occur.
