Thermal capacity P
G
for types O4C, O5C, O5R
With types O4C, O5C and O5R, the design of the input drive
assembly makes it the component that determines the thermal
capacity. If the calculated average oil temperature of the geared
motor is below the permissible oil temperature, then the plane-
tary gear unit can also be regarded as having sufficient thermal
capacity.
For further information, see Catalogs MD 50.1 and MD 50.11 or
contact the manufacturer.
