Motor Drive for Infrastructure Pump, Fan and Compressor Applications

March 20, 2019
The Sinamics G120X series from Siemens has power ratings of 1-700 hp (0.75-630 kW).

The drive can operate in a temperature range of -20 to +60 °C with any standard motor, including synchronous reluctance motors. It has an integral DC choke that improves harmonics and EMC performance; meets all the latest and upcoming UL, NEMA and EN/IEC standards for 2019 and beyond; and offers up to 100 kA short-circuit current rating (SCCR), ensuring enhanced product safety and energy efficiency. The unit integrates easily into existing applications and is configured for cost optimization and resource-saving operation, which ultimately helps reduce total cost of ownership. The drive’s compact design saves space in the control cabinet and can also be easily integrated into motor control center (MCC) solutions (including plug-in buckets). Even without an additional output reactor, the unit allows motor cable lengths of up to 150 m with category C2 or C3 filter and up to 450 m without a filter and have hardware-based SIL3-certified safety functions built in. The drive has Class 3C3 coating, which is suitable for harsh environments where the presence of corrosive gases such as hydrogen sulfide (H2S) is present. A high C2 or C1 EMC category ensures the drive can be used reliably in any kind of industrial or public network.
