SINAMICS Drives, SIMOTICS Motors & SENTRON Energy
Variable speed drives are one of the single largest energy-saving opportunities in any industrial plant — pumps and compressors running at reduced speed consume dramatically less power than those on fixed-speed starters. Siemens SINAMICS covers every power range from a small pump motor to an offshore gas compressor train.
SINAMICS Power Range — Match the Drive to the Machine
G120 / G120C
Low Voltage (400 V)
General pumps, fans, conveyors, mixers
G130 / G150
Low Voltage (690 V)
Large pumps, compressors, fans in MCC panels
S120
LV Modular (400 V)
Multi-axis, servo, pumping stations
S150
LV Cabinet (690 V)
High-dynamic fans, compressors, test benches
GM150 / SM150
Medium Voltage (2.3–6.9 kV)
MV motors for gas compressors, large pumps in O&G

SIMOTICS Motors
Siemens motors paired with SINAMICS drives for complete drive trains. The SIMOTICS range includes standard IEC motors (IE2–IE4 efficiency), explosion-proof motors (ATEX/IECEx) for hazardous areas, and high-speed motors for compressor applications.
- SIMOTICS GP/SD — general purpose (1M1)
- SIMOTICS XP — ATEX Ex d, Ex e, Ex nA
- SIMOTICS HV — high-voltage (MV motors)
- IE4 Super Premium Efficiency available
SENTRON Power Distribution
SENTRON is Siemens' power distribution portfolio — from molded-case circuit breakers to intelligent energy meters. Used in MCC panels and LV switchgear throughout plants.
- SENTRON 3VA/3VL — molded-case circuit breakers
- SENTRON 3WL — air circuit breakers (up to 6,300 A)
- SENTRON PAC3200/4200 — power meters (kWh, kVAr, PQ)

Energy Savings — Why Drives Matter
A centrifugal pump running at 80% of its rated speed consumes only 51% of the power (Affinity Laws: power scales with the cube of speed). Replacing a fixed-speed motor starter with a SINAMICS drive typically pays back in 12–24 months through energy savings alone.
