🔍 Key Concepts

• Podded propulsor construction – where is the motor located and how does power get into a rotating housing below the hull? • Difference between brushes and slip rings – which one is normally stationary and which is attached to the rotating part? • How AC power is usually transferred to a rotating assembly in marine applications.

💭 Think About

• Picture a podded propulsion unit: the electric motor is in the pod, which rotates to steer. How do you usually feed electrical power into something that must rotate freely without twisting cables? • In standard rotating electrical machines, what is mounted on the shaft (rotor), and what is fixed to the housing (stator) when using slip rings and brushes? • Look at each answer choice and ask: does it match the real-world roles of slip rings and brushes, or has something been reversed or over‑complicated?

✅ Before You Answer

• Verify which component is fixed to the ship’s structure and which rotates with the pod/shaft. • Check which element in standard practice is the sliding contact on the rotating part (brush or slip ring?). • Eliminate any option that uses a complicated synchro transmitter/receiver arrangement if the question is only asking about supplying power, not control signals.

By what means is electric current conveyed to the electric drive motor of a podded propulsor?

Current is conveyed from the source to a set of stationary brushes, then through a single rotating slip ring and then on to the motor windings.

Current is conveyed from the source to a set of stationary slip rings, then through a set of rotating brushes and then on to the motor windings.

Current is conveyed from the source to a set of stationary brushes, then through a set of rotating slip rings and then on to the motor windings.

Current is conveyed from the source to the stator of a synchronous transmitter, and by synchro action to the rotor of a synchronous receiver.
