Why Choose us

SLW Motor Highlights

  • 36mm diameter for higher torque stability

    The larger housing improves rigidity and supports higher torque transmission, making it suitable for compact mechanisms with heavier loads.

  • Stage-based length options for packaging control

    Each stage class has a defined length, so you can select ratio range and torque margin while keeping the overall envelope predictable.

  • Balanced selection from moderate to ultra-high reduction

    Lower stages support faster response and shorter builds, while higher stages prioritize torque margin and steadier low-speed output.

  • Custom shaft interface for repeatable coupling

    Defining the output shaft geometry early helps reduce adapter stacking and improves assembly repeatability under higher torque demand.

FAQ

Frequently Asked Questions

Higher stage counts are typically selected to reach higher ratios while controlling the gearbox length in compact assemblies.

How do I choose the gearbox stage level?
Choose 1–2 stages when you need shorter length and faster response. Choose 3–4 stages when you need higher reduction and torque margin.
Which ratios are best for moderate reduction needs?
Ratios such as 14:1, 27:1, and 29:1 are commonly selected when you need a balance between speed reduction and torque increase.
When should I select ratios above 189:1?
Higher ratios are typically selected for low-speed output where torque margin and steadier motion are priorities.
What is the advantage of using a 36mm gearbox diameter?
A larger diameter is typically selected to improve rigidity and torque capacity when the application load is higher.
What do you need to define a custom output shaft?
Your coupling method, assembly process, and any slip or positioning constraints.
