Question
a) If the torque pulled from the shaft is doubled while the asynchronous motor is working in the linear operating zone, how does the slip and speed of the motor change? (Note: Torque value doubled is smaller than maximum Torque) b) What are the differences and advantages of squirrel cage and ring asynchronous motors compared to each other? c) What are the problems caused by stray inductances in asynchronous motors and transformers? d) What measures can be taken to reduce Eddy losses? e) How does the starting torque change if the supply voltage of the induction motor is doubled? f) If the induction motor reaches synchronous speed, what changes are observed in the operation of the induction motor? g) What is an advantage if the starting Torque of the induction motor is higher than the nominal load Torque? h) What are the main differences when the equivalent circuits of transformer and asynchronous motor are examined?
