Motors for Ship Propulsion [PDF]
Proceedings of the IEEE, 2015 Electric propulsion of ships has experienced steady expansion for several decades. Since the early 20th century, icebreakers have employed the flexibility and easy control of direct current (dc) motors to provide for ship operations that split ice with back and forth motion of the ship.
