A Motor Module comprises a self-commutated inverter with IGBTs. It generates a variable voltage with variable frequency from the DC link voltage that feeds the connected motor.
Several Motor Modules can be interconnected through a common DC bus. This makes it possible to exchange energy between the Motor Modules. This means that if a Motor Module is in the generator mode, this energy can be used by another Motor Module operating in the motor mode.
Motor Modules are controlled by a Control Unit.
Liquid-cooled Motor Modules are available for applications where installation space is restricted and for plants or machines that cannot be equipped with air-cooled drive units as a result of critical environmental conditions.
