Electrical Propulsion

Question 1

Propulsion motor output

Answer 1

• Output if the 21MW generator supplied to the bus bar is connected to the 19MW advanced induction propulsion Motor.
• This is done through propulsion motor feeder breaker.

Question 2

Electrical propulsion

Answer 2

Propulsive power is provided via two independent shafts driven by the propulsion motors.

Each propulsion motor has a total of 15 phases.

Supplied by the 3 independent 5 phase converter channels.

The channels are contained in the converter regulator.

Question 3

3Ø (3 Phase)

Answer 3

Each phase is 120° different from the next on the view of an oscilloscope.

Question 4

Electrical propulsion

Channels

Answer 4

Each propulsion motor can run on 1,2 or 3 channels.

The number of channels used is dependent on power requirements.
