(1) Vmin water = 0.2 m/s. Standard windings for water temperature up to 45 °C.<br />
(2) Vmin water = 0.2 m/s. Special windings for water temperature up to 65 °C.<br />
(3) Vmin water = 0.5 m/s. Standard windings for water temperature up to 45 °C.<br />
(4) Vmin water = 0.5 m/s. Special windings for water temperature up to 65 °C.<br />
(5) Vmin water = 0.5 m/s. Standard windings for water temperature up to 40 °C.<br />
(6) Vmin water = 0.5 m/s. Special windings for water temperature up to 60 °C.<br />
EXAMPLE:<br />
An FW845T405, 45 kW motor must work in water at a temperature of 40°C.<br />
Motor power at 40°C = 45 x 0.83 = 37.4 kW<br />
