The great advantage of the double squirrel-cage induction motor over single cage rotor is that its _________

Correct Answer: starting current is lower
The outer cage has higher resistance and low reactance while vice versa for the inner cage. So at starting the current is confined to outer cage with the reduction in starting current improving the torque.

The advantage of the double squirrel cage induction motor over a single cage rotor is that its _______

Relatively a squirrel-cage induction motor is advantageous over wound rotor type induction motor of identical rating due to ___________

(I) Even at no load a large 3-phase squirrel- cage induction motor is started at reduced voltage than rated. (II) If a large 3–phase squirrel-cage induction motor with no load is started at full voltage, it will be damaged.

Wound rotor induction motor has better ________ characteristics than Squirrel cage induction motor.

A wound rotor induction motor is preferred, as compared to squirrel cage induction motor, when major consideration is

Hotel Aditya has 10 single AC rooms, 5 double AC rooms and 18 non AC rooms. The fixed monthly rent of hotel is 150,000. The per day maintenance cost is Rs. 100 for double AC room, Rs. 75 for single AC room and Rs. 40 for non AC room. The per day charges are Rs. 600 for double AC room, Rs. 400 for single AC room and Rs. 250 for non AC room. In April 2003, the occupancy rate of non AC room was 50%, 70% of single AC room and 40% of double AC rooms. Find the profit/loss % for that particular month.

In double cage induction motor, inner cage has ___________

In case of a double cage induction motor, the inner cage has

If the squirrel-cage induction motor is replaced by a solid cylinder in an induction motor its slip will ____________

In a three phase induction motor of rotor impedance as (0.2+j0.2), rotor current in each phase lags behind the generated emf in that phase to rotor by a power factor angle of _________
