which starter is used for synchronous motor..

Answer / mallikarjun

At first , the synchronous motor is coupled with induction
motor then the synchronous motor will run as a induction
motor and then the d.c supply is given to the field winding
of the synchronous motor ,the rotor will tends to magentic
locking with stator rotating field then that synchronous
motor wii run at synchronous speed

which starter is used for synchronous motor..

Answer / ed

Across the line Starter.
with time delay relay or current sensing relay or
speed monitor relay to
energize the field when the motor is close to
synchronous speed

For above 600 volt motors, a Circuit Breaker can be
used instead of a starter.
