How many slip rings does wound rotor induction motor has?Question 2Select one:a.3b.1c.2d.4

When induction motor is at standstill, slip of the machine will be:Question 5Select one:a.0b.1c.Infinited.-1

A 40 kW, 3-phse slip ring induction motor of negligible stator impedance runs at a speed0.96 times synchronous speed at rated torque. The slip at maximum torque is 4 times the fullload value. If the rotor resistance of the motor is is increased by 5 times, determine,(i) The speed, power output and rotor ohmic losses at rated torque(ii) The speed corresponding to maximum torque.Neglect mechanical losses.

How does the current appears in rotor of squirrel cage induction motor?Question 6Select one:a.From external power supplyb.By inductionc.Through slip rings

Slip of 3-Phase Induction Motor in motor mode should always beQuestion 3Select one:a.Zerob.0..1c.Equal to 2d.Greater than 1

10 kW, 6-pole, 50 Hz, 3- phase induction motor has linear torque-slip characteristicsbetween zero torque and maximum torque. The slip at which maximum torque of 520 Nmoccurs is 0.2. For mechanical losses of 600 W, find the speed at which motor would run whiledelivering rated shaft power.
