There are a Transformer and an induction machine. Those two have the same supply. For which device the load current will be maximum? And why? Last Answer : The motor has max load current compare to that of transformer because the motor consumes real power and the transformer is only producing the working flux and it’s not consuming. Hence the load current in the transformer is because of core loss so it is minimum....
Why squirrel cage induction motors are not used for loads requiring high starting torque? Last Answer : Squirrel cage motors are started only by reduced voltage starting methods which lead to the development of low starting torque at starting. This is the reason why squirrel cage induction motors are not used for loads requiring high starting torque. ...
