Question 1 of 27070

Q

The propulsion motor most often utilized in an AC drive system operating in the moderate to high power range is of what type?

🔍 Key Concepts

• Induction motors vs synchronous motors in AC drive applications • How starting torque, speed control, and ruggedness affect motor choice for moderate to high power drives • Why certain rotor constructions (wound rotor vs squirrel-cage) are preferred in industry

💭 Think About

• For an AC drive in the moderate to high power range, which motor type is most common in industry for pumps, fans, and propulsion systems? • Which motor type combines simplicity, durability, and low maintenance while still working well with variable-frequency drives (VFDs)? • Among the options, which motor construction is usually more complex and expensive, and therefore less likely to be the most commonly used?

✅ Before You Answer

• Identify which options are induction motors and which is a synchronous motor • Consider which rotor type is mechanically simple and rugged and often cast in aluminum or copper bars • Think about which design is most widely used in shipboard and industrial AC drive systems, not just for small fractional horsepower motors
