Introduction
The
synchronous motor is one type of 3-phase AC motors which operates at a constant
speed from no-load to full load. It is similar in construction to 3-phase AC
generator in that it has a revolving field which must be separately excited
from a DC source. By changing the DC field excitation, the power factor of this
type of motor can be varied over a wide range of lagging and leading values.
This motor is used in many applications because of its fixed speed from no-load
to full load, its high efficiency and low initial cost. It is also used to
improve the power factor of 3-phase AC industrial circuits.
