(1) Thermal conditions:
Ambient temperature 20°
C
Winding temperature rise 120°
C
Stator housing in contact with the ambient air or integral on all its peripheral area with a metallic armature in contact with the ambient air.
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.
Other speed characteristics are available, please contact us.
