Q.

3 phase synchronous motor needs

  • A3 phase AC supply only
  • B3 phase AC supply as well as single phase AC supply
  • C3 phase AC supply as well as DC supply
  • DDC supply only
Correct Answer : (C)

3 phase AC supply as well as DC supply

Hints :

3 phase synchronous motor needs 3 phase AC supply as well as DC supply.
