Shunt connection has been recently proposed by the authors to attain fast starting of slip-ring induction motors. Torsional torques, which might be experienced with this connection, is a reservation of this method and should be investigated. Therefore, this paper analyzes the expected torsional problems of the shafts of these motors when driving distributed inertias. The analysis aims at investigating the developed pulsating torque, the resulting torsional oscillations, the transmitted torques, and the twist angles at different shaft sections. Effects of motor parameters on the torsional oscillation problem are studied. For this purpose, a rigorous mathematical model is presented and simulated by a developed computer program.
