The specs are extremely impressive.
Looking at a 12.56 kW motor, the D127, 92% efficiency, 3600 rpm.
Lower revs, for boats esp. direct drive, is better.
So 8% => 1 kW heater.
I suspect the cooling is quite large and robust on both eletronics and
motor end ... air-cooling 1 kW permanently is non-trivial.
Anyway, I am officially impressed, very.
I would still prefer a non-brushed solution. And I think the brushes
will fail in saltwater environment, unless the boat is constantly in use.
Its only IP20, and looks very open frame.
IF used on lakes, I think the issue is 50x less, ie non-existent.
I live next to 2-3 marinas, on the coast of Spain, near seashore.
Anything conductive rusts very fast.
