GE DS3800NDAC Sequence control card

The specified ratings refer to a max. ambient temperature of 40 °C and mounting of the motor to an aluminium plate with a max. temperature of 40 °C and an installation altitude of max. 1000 above seal level. Minimum seating: 2.5 x the area of the motor flange Thickness of seating: min. 10 mm If the motor is to be mounted insulated (no heat discharge through the flange), the rated torque needs to be reduced. From an installation altitude of 1000 m above sea level a power reduction of 1 % per 100 m is required. The max. installation altitude is 4000 m. With ambient temperatures > 40 °C a power reduction of 1 % per 1 °C is required. The max. ambient temperature is 50 °C

The table specifies the max. 

permissible transverse force (radial force FRm) at the point of application I/2 and the max. permissible axial force FAm for a life of 20,000 h. A transverse force not acting on the centre of the shaft end can be simply converted to the changed lever ratios. Either the permissible radial force or the axial force may be applied to the motor shaft!
