xplain in detail d pr. of synchronous motors? why syn.
generators r used for the production of electricity?
Answer Posted / ranjeet rohilla
synchronous machines have capability to work on different
power factor(or say different imaginary power levels) by
varying the field emf.
However not only synchronous generators are used for
production of electricity. In case of wind power, induction
generator are used and for controlling the imaginary power
capacitor banks are used.
