For an even higher degree of redundancy on board, the redundant power system ABS-R2S is not only physically separated, but also has each propulsion motor built with two stator windings, each capable of delivering full power.
What is ABS-R2S+ two windings on propulsion motor
This highly reliable architecture where two circles in the motor represent redundant stator windings.
In the foregoing ABS classifications, we note that R denotes redundancy, 2 denotes two alternate parallel paths of powering the loads, S denotes physical separation, and + denotes additional reliability features.
