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
reactor cabinet.
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.
① Branch (identical power cells connected in series)
② Power cell
③ Bypass switch (optional)
④ Actual value sensing
⑤ Branch reactor
