Propulsion engine K11 Alpha

electricboating

Simply the most powerful 11" motor we have ever built. It can supply 50kW/85Nm nominal and at 75kg is 8% lighter than K11 250V. Efficiency is also increased to 88.7%. The back flange is custom designed to allow as much air through as possible. Shaft mounted fan is out while forced air cooling is standard. This makes the motor very quiet even at high speed and ventilation is not dependent on rpm. We have machined platforms in the motor case with threads so expensive motor mounts are no longer needed. An rpm sensor bearing can be ordered separately.
