rotation of dc shunt motor is revers by using 2
methods,which method is best and why??
(please answer if you know correct answer)
Answer Posted / marimuthu jayaseelan
The direction of rotation of a DC shunt motor can be
reversed by changing the polarity of either the armature
coil or the field coil.
you can reverse the direction by simply reversing the
armature leads. The same can be done with a shunt motor and
a compound motor,
You also can reverse direction by reversing field leads;
however, you run the risk of changing a cumulative compound
motor, which is inherently stable, into a differential
compound motor, which is somewhat unstable.
