Why Choose us

SLW Motor Highlights

  • Torque scaling with stage selection

    Move from 1-stage to 4-stage configurations to increase rated torque capacity, while keeping a compact 22mm gearbox diameter for tight builds.

  • Efficiency as a selection trade-off

    Higher stage counts expand ratio range but reduce efficiency, so ratio selection should follow duty cycle needs rather than targeting maximum reduction by default.

  • Wide ratio range for one mechanical interface

    With ratios from 5 to 1080, you can keep the same gearbox footprint and adjust output speed and torque based on different mechanisms or load profiles.

  • Output shaft customization supports higher torque interfaces

    As torque increases at higher reductions, defining the shaft end and coupling method early helps reduce slip risk and assembly variability.

FAQ

Frequently Asked Questions

Higher stage counts are typically selected to reach higher ratios and torque margin within the same gearbox diameter.

How do I choose between 1-stage, 2-stage, 3-stage, and 4-stage options?
Use lower stages for better efficiency and faster response. Choose higher stages when you need higher reduction and torque margin within the same diameter.
When should I select ratios above 300?
High ratios are typically selected for low-speed output and higher torque margin, especially when the load is heavier or requires steadier motion.
Why does efficiency drop as stages increase?
Additional stages introduce more gear meshes, which increases internal losses even while enabling higher reductions.
What does rated torque vs allowable peak torque mean for sizing?
Rated torque guides continuous operation sizing. Allowable peak torque is for short transient events such as acceleration or brief obstruction, not sustained load.
What information is needed for a custom output shaft?
Your coupling method, assembly approach, and any slip or positioning constraints, plus whether the load is mainly axial, radial, or mixed.
