Motor Module with external air cooling

Description

A Motor Module with external cooling is a power unit (inverter) that provides the power for
the connected motors. Power is supplied by the DC link of the drive unit. A Motor Module
must be connected to a Control Unit via DRIVE-CLiQ. The open-loop and closed-loop control
functions for the Motor Module are stored in the Control Unit.
Motor Modules with external air cooling are offered as Single Motor Modules and Double
Motor Modules. One motor can be connected to Single Motor Modules and 2 motors can be
connected to Double Motor Modules.
External air cooling uses the "through-hole" method. The power unit and its heat sink can be
inserted in a rectangular knockout at the rear of the control cabinet and mounted with a seal.
The heat sink fins and the fan (included in the scope of delivery) project beyond the rear of
the control cabinet and the heat is dissipated outside the control cabinet or in a separate air
duct.
