🔍 Key Concepts

• Synchronous motor construction – difference between stator (AC) and rotor (field DC) in a synchronous propulsion motor • How DC is normally supplied to a rotating field winding in electrical machines • Differences between commutator systems (DC motors) and slip ring systems (AC/synchronous motors)

💭 Think About

• Think about what part of the motor actually rotates and what part is stationary in a synchronous azipod propulsion motor. • Ask yourself: when you need to feed DC to something that is spinning continuously, what common mechanical method is used to transfer current from a fixed supply to a rotating winding? • Consider which option is normally associated with DC motors and which is normally associated with AC synchronous or wound‑rotor motors.

✅ Before You Answer

• Identify which components are typically used to transfer electrical power from a stationary source to a rotating winding. • Distinguish between commutator bars (segmented, used for DC armature current switching) and slip rings (continuous rings, used mainly for feeding rotor windings). • Verify which of the choices is the standard method for supplying steady DC excitation to a synchronous rotor without switching the current as it rotates.
