About SIEGMA Industrial Systems.
Superior quality industrial products, delivered through a focused, deliberate catalog — the gearmotors, brushless motors, and reducers that show up in real industrial production environments.
A focused motion-control brand.
SIEGMA Industrial Systems is a motion-control brand built around a deliberate, narrow catalog. The SIEGMA line was created to bring a focused selection of motion-control hardware to North American buyers under a single, consistent brand — with manufacturer-grade documentation and a clear, engineer-readable specification format.
What we make
Our catalog covers five product families: right-angle hypoid speed reducers (KM Series), AC induction gearmotors (IK Series with GN parallel-shaft gearheads), AC right-angle gearmotors (IK / RK with GU spiral-bevel or worm gearheads), DC brushless motors (Z_BLD Series), and DC brushless gearmotors (Z_BLD with GN, GU, or L-type heads).
Each line is selected for industrial drive applications — conveyors, packaging machinery, mixers, automated assembly, food processing — rather than consumer or hobbyist use. Continuous-duty ratings, real insulation classes, IP54 terminal-box variants, and standard NEMA-compatible flanges are the baseline.
Sourcing & manufacturing
SIEGMA products are built through long-running international manufacturing partnerships, primarily in Asia. We focus on suppliers whose factories already serve global motor brands, so the underlying production quality is well-understood — we just bring the line to market under our own brand and our own catalog discipline.
Engineering philosophy
We keep the catalog narrow on purpose. A small number of well-documented families is easier to specify, easier to stock, and easier to support than a sprawling product matrix. Every model in the line is intended for real production duty, with the kind of mechanical and electrical detail engineers need to commit to a design.
What this site is
This site is product information, not a storefront. It exists so that engineers, plant managers, and OEM specifiers can review the SIEGMA line, see the specifications, and download the manufacturer catalogs for evaluation.
