Q

Universal motors will operate on AC or DC current. In what application is this type of motor generally?

🔍 Key Concepts

• Universal motors characteristics (speed, torque, size) • Typical power source and usage of portable equipment aboard ship • Differences between motors used for continuous heavy-duty service vs. intermittent/light portable service

💭 Think About

• Which type of equipment commonly needs to work on either ship’s AC power or from a DC/rectified source? • Which of the listed applications normally requires large, continuous-duty motors with smoother, quieter operation rather than high-speed, lightweight motors? • Think about which devices are usually small, high-speed, and often hand-held or easily moved around a vessel.

✅ Before You Answer

• Identify which listed application is typically small, lightweight, and high-speed. • Eliminate options that usually use large, continuous-duty AC induction motors. • Confirm which application commonly needs motors that can operate on both AC and DC supplies.
