Please typed by computer not hand write.. What happens to the rotor of a synchronous motor when load torque is applied to the motor? What is the pull-out torque of a synchronous motor? At which angle and relative position (leading or lagging) does the rotor of a synchronous motor pull out of synchronization with respect to the rotating magnetic field? What is the relationship between the pull-out torque of a synchronous motor and the motor field current?
