Question 208Electricity & Electronics - 1st Asst/Chief
70% to passWhat type of motor is generally used in DC propulsion drive systems?
Ashunt wound
Bdifferentially compounded
Cseries wound
Dpermanent magnet
AI Explanation
The correct answer is A) shunt wound. Shunt wound motors are commonly used in DC propulsion drive systems for Coast Guard vessels. This is because shunt wound motors have good speed regulation and can provide the necessary torque and speed control required for marine propulsion applications. In contrast, series wound motors are not well-suited as they have poor speed regulation, while differentially compounded and permanent magnet motors are less common in this specific application.
