A13 A14 A15 A16 A17 A18 A19 A20 In the torque-slip characteristics of 3-phase induction motor, if the speed of the induction motor is beyond synchronous speed then the machine performs as a Choose True or False For any given capacity, three-phase ac machine is smaller in size than single-phase ac machine. The autotransformer size is larger when compared to two winding transformers. Series generator cannot be used for generation purpose. Losses in DC machines should be estimated to know the efficiency and temperature rise in the machine. Mechanical power developed by the de motor is maximum when back emf is equal to the supply voltage. Star delta starter is one of the method used for starting the three-phase induction motor. The 3-phase slip ring induction motor is used in cranes and hoists. True/False True/False True/False True/False True/False True/False True/False
