Siemens & Innomotics SIMOGEAR Parallel Shaft Geared Motors
Brand: Siemens / Innomotics | Series: SIMOGEAR F Series (F29, F39, F49, F69, F89, F109 to F189 Range)
Brand Ownership & Lineage Notice — Siemens to Innomotics:
SIMOGEAR is the modern, highly efficient parallel shaft geared motor platform developed by Siemens as the direct successor to the legacy Flender MOTOX F series. Following Siemens' corporate restructuring of its electric motor and geared motor division, the entire SIMOGEAR portfolio has been integrated under the Innomotics brand identity.
Engineering Advantage & MOTOX Retrofit Compatibility:
• SIMOGEAR F series parallel shaft units offer high space-saving advantages with narrow housing width, up to 96% transmission efficiency per stage, and plug-in motor pinion interfaces.
• Integrated with Siemens/Innomotics LE/LA motors (such as 1LE0003 and 1LE1501 IE3 motors) across frame sizes IEC 63 to IEC 225M.
• 100% Direct Drop-in Retrofit: SIMOGEAR F sizes (F29, F39, F49, F69, F89, F109, F129) feature standardized hollow/solid output shafts and torque arm dimensions designed to directly replace legacy Siemens MOTOX F gearmotors (F38, F48, F68, F88, F108, F128) with zero frame modification.

The SIMOGEAR Parallel Shaft Helical Geared Motor Series (F Series) provides an exceptionally narrow, space-saving, and high-efficiency solution for shaft-mounted and conveyor applications. Matched with Siemens / Innomotics SIMOTICS AC motors from 0.09 kW up to 55 kW, SIMOGEAR F delivers nominal output torques from 130 Nm up to 19,000 Nm. Available in solid shaft (F/FF), hollow shaft with keyway (FA/FAF), hollow shaft with shrink disc (FAS/FASF), and rubber-buffer torque arm configurations, SIMOGEAR F is heavily specified across crane hoists, belt conveyors, agitators, wastewater treatment clarifiers, and material handling systems.
