Figure 3-3 Block Diagram: Motor Module Employing M2C Technology - Siemens SINAMICS PERFECT HARMONY GH150 Operating Instructions & Installation Instructions

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
The inverter unit has three phases. Each phase comprises two so-called M2C branches. The
six branches of the M2C inverter each consist of identical power cells connected in series. The
phase of the voltage-source DC link drive is realized employing M2C technology using power
cells connected in series for two branches.
