15. External vent (optional)
Functional description of vent motors
The fan cowl and fan blade of the drive motor are removed and replaced by the extended fan cowl with
integrated fan. The fan has a direct mains connection, and therefore delivers the maximum quantity of
cool air to protect the motor against overheating at all speeds. Separate fans can be operated over a wide
voltage range, according to the technical data below. They can be connected to three-phase or alternating
current power supply, if connected according to the instructions. For single-phase operation, an operating
capacitor is included in the terminal box (see electrical wiring diagram). The fan motors work according to
the direction of rotation. The air flow must be directed towards the motor.
Special versions available
• Extended fan cowl (for operation with tachogenerator or motor brake)
• Different mounting bracket
• Different fan cowl diameter
