In the standard version, the rotor has vibration severity gradeA. Finely balanced rotors are
used in the standard version.
The technical data for the optional monitoring equipment can be viewed in the circuit
diagrams, on the rating plate or in the special order documents.
The stator housing and bearing shields are made of die-cast aluminum or cast iron.
The surface of the stator housing is equipped with cooling ribs and a mounted terminal box
or motor connector.
12.2.4 Cooling
NOTICE
Dust deposits prevent heat radiation.
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the geared motor free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sucient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80° C, please contact Technical Support.
The motor is designed to be cooled by means of ns. An external fan draws in the cooling
air through the aperture in the fan cover and blows the air over the surface of the stator
housing.
12.2.5 Terminal box and application box
The following are contained in the motor terminal box:
• Terminals for the motor (terminal board)
• Terminals for checking equipment
• Connection for brake
The number of available terminals is shown in the circuit diagrams. The circuit diagrams are
located in the terminal box.
