It features low-noise operation due to the helical gear stage, suitable for noise-sensitive environments.
The robust cast iron housing enhances durability, with optional corrosion-resistant coatings for harsh conditions.
Modular and scalable, it supports power ranges from 0.12 kW to 7.5 kW and high reduction ratios.
What is the GS Series Helical-Worm Geared Motor?
The GS Series is a type of geared motor that integrates helical and worm gearing for right-angle torque transmission. It consists of a single-stage helical gear stage followed by a single-stage worm gear stage, providing high reduction ratios in a compact footprint. It's designed for mechanical-electrical integration, allowing combination with various motors and electronic speed variators.
What mounting types and configurations are available?
Type S: Foot-mounted with solid shaft Type SF: B5 flange-mounted with solid shaft Type SA: Hollow shaft Type SAF: B5 flange-mounted with hollow shaft Type SAZ: B14 flange-mounted with extended bearing housing Type SH: Hollow shaft with shrink disk Type SHF: B5 flange-mounted with hollow shaft and shrink disk Type SHZ: B14 flange-mounted with hollow shaft and shrink disk Type SAT/GSHT: Torque-arm-mounted with hollow shaft Type S..SZ..AD..: Shaft input Type S..R: Combined with Series R for extended ratios General options include foot, flange, shaft, or vertical mounting in any orientation.
What are the main features and advantages?
High Torque and Ratio: Delivers large transmission ratios for slow-speed, high-load applications while maintaining steady, right-angle output. Efficiency and Quiet Operation: Helical-worm design reduces noise and vibration compared to plain worm gears; linear power transmission dampens torque impulses. Compact and Robust: Modular construction with no oil leakage; higher rigidity and vibration resistance via all-in-one box design. Customization: Compatible with AC induction motors (IE2/IE3), servo motors, or keyed input shafts; options for brakes, feedback devices, and environmental seals. Cost-Effective: Simple mechanical structure yields higher efficiency and lower noise than traditional worm units, ideal for budget-conscious setups.
What are typical applications?
Material handling (conveyors, elevators) Mixers, agitators, and crushers Food processing and packaging Cranes, hoists, and automation equipment Mining, cement, steel, and plastic/rubber processing It's versatile for any sector needing torque/speed tailoring in compact spaces.
What are the operating conditions?
Ambient Temperature: -10°C to +40°C Altitude: Up to 1,000 m above sea level Environment: Suitable for general industrial sites; optional washdown/corrosion protection available. Avoid extreme dust, humidity, or corrosive atmospheres without modifications.
How do I select the right model?
Provide details like required ratio, motor speed, mounting dimensions, output torque, and input power. The modular system allows tailoring—e.g., combine with other reducers for ultra-high ratios. Consult the catalog for torque/speed charts or use online configurators from similar series (e.g., SEW-Eurodrive equivalents).
What maintenance is required?
Lubrication: Use synthetic or mineral oil per manual; check levels every 1,000–2,000 hours of operation. Inspection: Monitor for unusual noise/vibration; inspect seals and bearings annually. Service Life: Gears and components are designed for 20,000+ hours with proper use; modular design simplifies part replacement. Always follow the user manual for heat dissipation and alignment checks.
How does it compare to other geared motors (e.g., pure worm or helical)?
Vs. Pure Worm: Higher efficiency (up to 13% better), quieter, and smoother due to helical pre-stage, but still self-locking for load holding. Vs. Pure Helical: More compact for right-angle needs; lower efficiency but superior high-ratio performance in small spaces.
