A Motor Module is a 3-phase converter (IGBT technology) that supplies energy to the
connected motor. Energy is supplied to the Motor Modules via the DC busbar.
Motor Modules in chassis format are available for the following voltages and power ratings:
Line voltage
DC link voltage
Unit rating
380 to 480 V 3 ph. AC 510 to 720 V DC 150 ... 1000 HP (110 to 800
KW)
500 to 690 V 3 ph. AC 675 to 1035 V DC 75 ... 1250 HP (75 to 1200 KW)
The available shaft output can be increased by connecting up to 4 Motor Modules in parallel.
These modules are operated on one Control Unit and feed one motor.
Note
Parallel connection to a common Control Unit
Note that the Motor Modules connected in parallel are operated on a common Control Unit.
