Device for driving a ship incorporates two drive motors of varying power and a drive shaft with two electric drive motors designed as multi-strand AC motors with a power converter feed.

摘要

To optimize the energy balance in a drive device for a navy ship that has two different operating ranges for a propeller, a drive shaft is allocated two electric drive motors designed as multi-strand AC motors with a power converter feed. These motors differ in their power rating at a ratio of 20:1. Rotors (12,22) for both drive motors have common bearings in two sets of bearings (16,26) fitted on either side of the rotors.
