A
synchronous phase modifier as compared to a synchronous motor used for
mechanical loadhave :
Larger shaft and higher speed.
Smaller shaft and higher speed
Larger shaft and smaller speed.
Smaller
shaft and smaller speed.
Smaller shaft and higher speed
●A
synchronous phase modifier is a type of synchronous motor that runs without
mechanical load, and is provided with means for varying its power factor to
simulate an inductive or capacitive reactor which is used in voltage regulation
of alternating current power system.
●Due
to no load, the motor can be operated at highest possible speed, hence designed
for higher speed having smaller shaft.
Hence,
the correct option is (B).
