Siemens expands Sinamics G120P series

In line with Siemens’ Integrated Drive Systems strategy, the drive is optimally adapted to operate with Simotics severe-duty and flexible-duty motors from Siemens. For example, the inverter output currents have been adapted to the motor rated currents and the motors to the rated pulse frequencies of the inverters.

As the components interact as an integrated drive system, the voltage is optimally utilised and the noise level of the motor is also reduced by 4 dB. The efficiency of the overall system is 98 per cent. The new inverter also has application-specific functions that enable efficient operation of pumps.
