Technical description
4.4 Backstop at the motor
4.2
Cooling
The motor is designed for surface cooling and has cooling ribs. An external fan draws in the
cooling air through the opening in the fan cover and blows the air over the surface of the stator
housing. As standard, the fan is driven via the motor shaft IC411. IC416 forced ventilation is
optionally available. In special cases, there is also the non-ventilated motor variant IC410.
NOTICE
Consequence of dust deposits
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the motor free from dirt, dust etc.
4.3
Condensation drain hole
Condensation accumulates inside the motor as result of environmental effects. Condensation
results in corrosion and reduces clearances and creepage distances.
The condensation is drained to the outside through the condensation drain hole. Depending
on the mounting position, the drain holes are located at the DE and/or NDE of the motor.
Ensure that the geared motor is always mounted in the correct position.
Note
The condensation drain hole cannot be selected in conjunction with explosion-protected motors
(MB motors) or worm geared motors S.
4.4
Backstop at the motor
NOTICE
Service life of backstops
Input speeds below 1 000 r/min or frequent starting and stopping operations (≥ 20 starts/stops
per hour) significantly increase the wear of the backstops and therefore reduce the service life.
Ensure that the backstop is replaced in time for frequent starting and stopping operations.
NOTICE
Damage or destruction due to incorrect direction of rotation
Do not run the motor against the backstop.
Observe the direction of rotation arrow on the motor.
