Challenge Problems
Push your limits with advanced challenges
A three-phase motor has 8 poles and is powered by a 50 Hz supply. Calculate its synchronous speed and discuss the significance of the result.
💡 Hint: Think about how pole arrangements impact motor design.
If you were to increase the supply frequency to 60 Hz for the same 8-pole motor, what will happen to its synchronous speed? Show the calculation.
💡 Hint: Recall the relationship between frequency and speed.
