Basic Line Module

The Basic Line Module generates a DC voltage providing energy for the modules connected to
the DC link. In this case, the line voltage fluctuations must remain within the permissible
tolerance range. Depending on the design, the Basic Line Module consists of series-connected
six-pulse rectifiers. RC combinations are provided to protect the diodes.

Motor Module employing M2C technology

The Motor Modules provide the power for the connected motor. The Motor Module is supplied
with power for the motor via the DC link.
The Motor Module is built in M2C technology with IGBT semiconductors. Motor Modules in
M2C technology provide the motor with almost sinusoidal voltages. The Motor Module in M2C
technology comprises a submodule and a branch reactor cabinet.
● The power cells are housed with the IGBT semiconductors in the submodule cabinet.
● The branch reactors and the associated measuring equipment can be found in the branch
