Siemens & Innomotics SIMOTICS HV High-Voltage Motors
The SIMOTICS HV platform constitutes the ultimate heavy industrial electric drive architecture originally developed by Siemens for mega-watt power ratings across global infrastructure and resource sectors. Following the corporate restructuring of Siemens' large-scale drive and motor businesses, this specialized high-voltage engineering portfolio operates and expands under the independent global identity Innomotics.
Engineering Excellence & Heavy Power Grid Compliance:
⢠Broad High-Voltage Range: Engineered for operation at grid voltages of 3.0 kV, 3.3 kV, 6.0 kV, 6.6 kV, 10.0 kV, 11.0 kV, and 13.8 kV (50 Hz and 60 Hz), with power outputs spanning from 150 kW up to 20,000 kW and beyond.
⢠Diverse Cooling Topologies: IC411 (fin/rib-cooled cast iron or fabricated steel), IC611 (air-to-air heat exchanger), and IC81W (air-to-water heat exchanger) optimized for high power density and lowest acoustic footprints.
⢠MICALASTIC® VPI Insulation System: Vacuum Pressure Impregnation (VPI) insulation meeting Class F (utilized to Class B thermal limits) providing high dielectric strength, high thermal reserve, and exceptional resistance against moisture, salt spray, chemical vapors, and high-frequency inverter stress.
The Siemens & Innomotics SIMOTICS HV Series provides maximum operational reliability, world-class electrical efficiency, and proven ruggedness in the most challenging industrial applications. Available in squirrel-cage induction (HV Series / Compact-Plus) and wound-rotor slip-ring motor designs, these drives are configured for Direct-On-Line (DOL) grid starting or variable-speed operation paired with medium-voltage converters (such as SINAMICS GM150, SM150, and GL150). Featuring insulated rolling or hydrodynamic sleeve bearings, vibration monitoring sensors, anti-condensation heaters, and certified hazardous area protection (Ex ec, Ex eb, Ex pxb, Ex db), they serve continuous-duty crude oil pipeline pumps, mine shaft hoists, primary ventilation fans, blast furnace blowers, ball grinding mills, and water utility intake pumping stations.
