Siemens & Innomotics SIMOTICS 1LE0 Low-Voltage AC Motors
Brand: Siemens / Innomotics | Series: SIMOTICS GP & SD (1LE0, 1LE1, 1LE5 Range)
Brand & Ownership Evolution Notice:
To optimize its industrial operations, Siemens transferred its low-voltage electric motor business into an independent enterprise named Innomotics. The renowned SIMOTICS 1LE0, 1LE1, and 1LE5 three-phase asynchronous motor series are now manufactured and supplied under the Innomotics brand identity.
Regional Model Note: The 1LE0 Series is the primary standard model produced for the Asian / Chinese market, whereas 1LE1 / 1LE5 are the primary European and global models. Because they adhere to identical IEC frame sizes (B3 foot, B5 flange, B14 flange), Asian 1LE0 models offer 100% direct 1:1 dimensional interchangeability and cost-effective upgrade potential for overseas 1LE1 installations.

The Siemens SIMOTICS 1LE0 Series (including 1LE0001 IE2 and 1LE0003 IE3 Premium Efficiency) represents the industry benchmark for three-phase low-voltage squirrel-cage AC motors in general purpose (GP) and severe duty (SD) industrial applications. Available in cast iron or aluminum frames across IEC sizes 80 to 355 (0.55 kW to 1,000 kW), 1LE0 motors deliver high energy efficiency, robust thermal overload capacity (Class F/B insulation), IP55 protection, and low noise levels. They are heavily specified across centrifugal pumps, industrial fans, air compressors, belt conveyors, mixers, and general machinery drives.

Expert Selection & Retrofit Engineering Notes
WE DRIVE HONGKONG LIMITED specializes in providing technical sourcing and global supply solutions for the complete Siemens & Innomotics SIMOTICS Low-Voltage AC Motor family. Whether your facility requires standard general-purpose aluminum motors (1LE10), severe-duty cast iron motors (1LE0003 / 1LE15 / 1LE55), general industrial motors (1TL0), or explosion-proof hazard-rated motors (1MB0 / 1MB1), all units can be ordered pre-configured with PTC thermistors, space heaters, reinforced bearings for belt drives, or forced-cooling ventilation fans for inverter-fed VFD operations.
When servicing or replacing imported European machinery equipped with older 1LE10, 1LE15, or 1LA/1LG series motors, switching to Asian 1LE0 series models offers significant lead-time reductions and cost savings while maintaining 100% exact mounting alignment, thermal capacity, and IE3 energy efficiency compliance. Simply provide us with your motor nameplate order code (e.g., 1LE0003-1DB43-4AA4) or electrical rating, and our engineering team will deliver a 100% compliant proposal.
