🔍 Key Concepts

• Difference between motor synchronous speed and pump operating speed • Where the illustration lists Speed R.P.M. (SYN.) versus the pump Speed R.P.M. • How synchronous speed on an AC motor nameplate relates to a 60 Hz, 3‑phase supply

💭 Think About

• On the illustration, which table refers specifically to the motor rather than the pump? • In that motor table, what exact wording is used next to the speed value, and how does that relate to the word synchronous in the question? • Why is the pump speed slightly different from the motor’s synchronous speed on many AC motor‑driven pumps?

✅ Before You Answer

• Be sure you are reading the Motor Characteristics section, not the Pump Characteristics section. • Locate the line that includes Speed R.P.M. (SYN.) and match that number to one of the choices. • Verify that you are not choosing the 1150 RPM pump speed, which is the actual running speed, not the synchronous rating.
