State the functions and material used for the following parts of a 3-phase induction motor.
Explain the methods to get more starting torque in 3-phase slip ring induction motor.
The power input to a 500V, 50Hz, 6-pole, 3-phase induction motor running at 975 RPM is 40KW. The total stator losses (iron and stator cu loss) are 1KW, the friction and windage losses are 2 KW. Determine
State the losses occurred in 3-phase induction motor and state the ways to reduce these losses.
Draw the circuit diagram for No load and blocked rotor tests on 3-phase induction motor. Which measurements are taken during the tests? Also explain the purpose of these tests.
In a No load test, a 3-phase, star connected induction motor took 10A and total input power is 450 watt at a line voltage of 110V. If the stator resistance per phase is 0.05 ohm and friction and windage losses amount to 135 watt, determine
Explain how the power factor and armature current varies with change in field current for a particular load condition in a 3-phase synchronous motor.
A 1-MVA, 11-KV, 3-phase, star connected synchronous motor has an armature resistance and reactance per phase are 3.5 ohm and 40 ohm respectively. Determine the induced emf and retardation angle fully loaded and operated at unity power factor.
Draw and explain O.C.C and S.C.C of a typical 3-phase alternator and explain how the synchronous impedance can be determined?
A 3-phase, 12-pole, star connected alternator has 180 slots with 10 conductors per slot and conductors of each phase are connected in series. The coil span is 144°(electrical). Determine the phase values of emf if machine runs at 600RPM and the flux per pole is 0.06wb distributed sinusoidal over the pole.
Explain the effect of change in steam input and change in exciting current on the output power of a 3-phase synchronized alternator with grid.
What is synchronizing? State the conditions for synchronizing and explain how we can synchronize the incoming alternator with grid.
