SIMOTICS SD Cast-Iron Motors
Innomotics SIMOTICS SD Severe Duty motors — rugged cast-iron low-voltage motors from 0.09 to 1,000 kW, IE3/IE4 efficiency, on the 1LE1/1LE5 platform (Basic Line and Performance Line) — genuine motors sourced through authorized channels, with 24-hour response on stock and lead time for customers worldwide.
Genuine Innomotics SD cast-iron motors from SENTRADO
The Innomotics SD (Severe Duty) motors are the high-efficiency low-voltage motors with a rugged cast-iron housing, built for normal industrial environments as well as harsh process-industry conditions — dust, vibration, moisture and chemically aggressive atmospheres. The platform spans induction motors for direct-on-line and converter operation (IE1 to IE4, with IE4 available from 2.2 to 1,000 kW), plus converter-only synchronous reluctance and permanent-magnet variants up to IE5 system efficiency. The range is offered as Basic Line (1LE15) for machine building and the particularly rugged Performance Line (1LE16) with reinforced bearings and heavy-duty coating for the process industry. We supply these as genuine Innomotics motors sourced through authorized channels, with FOB, CIF or DDP terms and full export documentation. We reply within 24 hours with a human response on stock and lead time — contact us for live stock & lead time.
Innomotics is the dedicated motors and large-drives company spun off from the Siemens large motors business, combining more than 150 years of motor engineering. SENTRADO supplies genuine Innomotics SD motors sourced through authorized channels, with manufacturer documentation.

Selection & supply
Three ways our team supports your SD motor project: genuine motor supply, driven-machine selection and complete drive-system BOM handling.
Genuine motors for harsh environments
We supply genuine Innomotics SD cast-iron motors — Basic Line and Performance Line, IE3/IE4 — sourced through authorized channels. Share your driven machine (pump, fan, compressor, mill, conveyor) and our engineers verify frame, poles and torque class.
Engineering & selection support
Our engineers verify shaft height, power, voltage/frequency, mounting form (B3/V1/B35), protection (IP55-IP66), paint system (up to CX offshore), temperature class and converter duty against your application, and support Innomotics Configurator article selection.
Drive-system BOM handled
We can quote the complete drive train — SD motor, matched frequency converter, encoder/brake options, forced-ventilation and spare parts — in one shipment with export-grade packaging and full documentation.
Typical applications
The first-choice cast-iron motor for harsh environments — process industry, oil & gas, chemicals, mining, cement, metals and marine duties.
- Pumps, fans and compressors in process plants
