Cooling
NOTICE
High housing temperature
Dust deposits prevent heat radiation and cause high housing temperatures.
Keep the motor free from dirt and dust, etc.
The motors are designed for fin cooling; an external fan draws the cooling air in through the
opening in the fan cover and blows it across the surface of the stator frame.
2.3
Terminal box
In the motor terminal box, alongside the motor connection terminals (terminal board),
additional connecting clamps are available for monitoring equipment. The number of
available terminals is shown in the circuit diagrams. The circuit diagrams are located in the
terminal box.
2.4
Rating plate
The rating plate on the gearbox or geared motor is of coated aluminum foil. It is covered with
a special masking film which ensures permanent resistance to UV radiation and media of all
kinds, such as oils, greases, salt water and cleaning agents.
The adhesive and the material ensure firm adhesion and long-term legibility within the
operating temperature range from -40 °C to +155 °C.
The edges of the rating plate are paint-finished to match the color of the gearbox or motor to
which it is affixed.
In special cases, riveted or bolted metal plates are used.
