Challenge Problems
Push your limits with advanced challenges
A synchronous generator operates at 50 Hz and must produce 900 V. If the winding factor is 0.9, how many turns per phase are necessary if the magnetic flux is 0.2 We?
💡 Hint: Don't forget to re-arrange the equation correctly to solve for turns.
If the pole number of a synchronous generator changes from 4 to 6 while keeping the frequency constant at 60 Hz, what will be the new synchronous speed?
💡 Hint: You can solve the speed using the same formula; just adjust the pole count.
