Stator housing secured on a metallic frame having an area equal to twice the cross section of the housing. (2) Cold motor at 20° C (3) See torque vs speed characteristics on : http://www.alxion.com/CFN (4) Torque at stall or low speed. (5) Fluid input temperature should not be lower for avoiding condensation inside the motor. (6) For cooling fluid, use softened gycol-added water or fluids approved for closed cooling circuits.
