3000 RPM

3600 RPM

1800 RPM

1500 RPM

The maximum power a SM (10 MVA, Xs=2pu), haging 1pu open circuit voltage, can deliver at 1pu voltage is

0.5 MVA

10 MVA

5 MVA

2.0 p.u.

The rotor winding of a SM is fed by DC current

when static excitation is used

when brushless excitation is used

both in case of static and brushless excitation

only in case of cylindrical rotor machines

I stator and rotor north poles are aligned

power is at it maximum in generator operation

power is at its maximum in motor operation

power is zero

power depends on the stator's current
