Siemens & Innomotics SIMOGEAR Helical-Worm Geared Motors
Brand: Siemens / Innomotics | Series: SIMOGEAR C Series (C29, C39, C49, C69, C89 Range)
Brand Ownership & Lineage Notice — Siemens to Innomotics:
SIMOGEAR is the modern, highly efficient right-angle geared motor platform developed by Siemens as the direct successor to the legacy Flender MOTOX C 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 C series combines the high efficiency of a primary helical gear stage with the extremely quiet operation and high ratio capacity of a worm gear stage.
• Integrated with Siemens/Innomotics LE/LA motors (such as 1LE0003 and 1LE1501 IE3 motors) across frame sizes IEC 63 to IEC 160M.
• 100% Direct Drop-in Retrofit: SIMOGEAR C sizes (C29, C39, C49, C69, C89) feature standardized hollow/solid output shafts and torque arm dimensions designed to directly replace legacy Siemens MOTOX C gearmotors (C38, C48, C68, C88) with zero frame modification.

The SIMOGEAR Helical-Worm Right-Angle Geared Motor Series (C Series) provides a highly cost-effective, space-saving, and exceptionally quiet solution for right-angle drive applications. Matched with Siemens / Innomotics SIMOTICS AC motors from 0.09 kW up to 15 kW, SIMOGEAR C delivers nominal output torques from 45 Nm up to 1,590 Nm. Available in solid shaft (C/CF), hollow shaft with keyway (CA/CAF), hollow shaft with shrink disc (CAS/CASF), and torque arm configurations, SIMOGEAR C is heavily specified in conveyor drives, material handling systems, stage technology, food processing, and packaging machinery.
