Cooling for MAD motors
MAD motors with explosion-protection design are equipped with a fan
cowl for operation with an external fan.
Note:
The required fan and corresponding connection materials (air
duct, connection clamps, etc.) do not belong to the scope of
delivery of the motor; these must be provided by the machine
manufacturer.
MAD motors may be operated only if the fan provides the specified
minimum amount of air flow on the motor side. Therefore, when selecting
radial fans or central ventilation systems, take into account the length of
the air duct to be installed, as well as the air baffles. For further
information refer to the Chapter 9.8 “Motor Cooling” of the project
planning manual.

Cooling for MAF motors
The connection of the cooling system is done directly to the two
connecting threads on the motor side. The connecting threads have been
covered with protective caps at the factory.
The assignment of inflow (IN) and outflow (OUT) can be made as desired;
it has no influence on the performance data of the motor.
The following coolant connection threads are present, they depend on the
motor frame size.
