🔍 Key Concepts

• Formula for synchronous speed of an AC motor in RPM • Relationship between frequency (Hz), number of poles, and motor speed • Typical synchronous speeds for 60 Hz motors with different pole numbers (2, 4, 6, 8)

💭 Think About

• First, recall or look up the standard formula that links frequency and number of poles to synchronous speed. • Substitute 60 Hz and 8 poles into that formula carefully, watching units. • Compare your calculated value with the answer choices and think about whether 8 poles should give a higher or lower speed than 4-pole and 6-pole motors at 60 Hz.

✅ Before You Answer

• Make sure you are using the correct formula for synchronous speed, not slip or rotor speed. • Double-check your calculation of poles in the denominator (don’t confuse number of pole pairs with total poles). • Confirm that your result is a standard synchronous speed for a 60 Hz motor and matches one of the listed RPM values.
