Can the same motor be operated in both direction ?

Answer Posted / p.k.chadhar

In case of dc motors, change the direction of either
field current or the armature current. if u change both ,the
motor will run in the same direction as before.

For ac machines(3 phase) just by changing the phase connection
we can make the motor to run in opposite direction.
