Optimal Selection of Rotor Bar Number for Minimizing Torque and Current Pulsations Due to Rotor Slot Harmonics in Three-Phase Cage Induction Motors
The paper develops a method to choose the number of rotor bars in order to eliminate rotor slot harmonics in stator current spectrum and pulsation torques that are their consequence.Mains-fed, three-phase cage induction motors with the most common number of pole pairs and number apac1/60/1/cw of stator slots, that result in integer slot winding, ar
