railway RRB JE (CBT I + CBT II) Mock Test 2024 Electrical Machines Alternator and Synchronous Motors Synchronous Reactance
The above graph is the V-curve of a synchronous motor. The no-load, full load, and half load curves are mentioned in the graph. What will happen when the synchronous motor is operated at the lowest curve?
1
The motor will only take lagging current
2
The motor will only take a leading current
3
The motor will take no current.
4
It can take leading and lagging current by over or under exciting its field winding
