K11" Alpha

The most powerful 11" motor kostov motors 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

Diameter: 26.5cm=10.43" 
Length: 43.2cm=17"

Voltage: up to 250 VDC
