Description

A Motor Module with external air cooling is a power unit (inverter) that provides the power
supply for the connected motor(s). Power is supplied by means of 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.
Single Motor Modules and Double Motor Modules are available.
Just one motor can be connected to and operated using a Single Motor Module. Two motors
can be connected to and operated with a Double Motor Module.
External air cooling uses the "through-hole" method. This is a cooling method for SINAMICS
power units that is only available for booksize devices. The power unit and its heat sink can
be inserted in a rectangular knockout at the rear of the switching cabinet and mounted with a
seal. The heat sink fins and the fan (included in the scope of supply) project beyond the rear
of the switching cabinet and the heat is dissipated outside the switching cabinet or in a
separate air duct.
