Key Features

This model is a low-voltage BLDC gear motor with a ratio-to-length selection logic, designed for compact mechanisms that need repeatable output speed steps and a controlled gearbox envelope.

  • 3V–12V applied range supports battery-powered and compact DC systems
  • Ratio ladder from 4 to 500 lets you pick output speed by gearing instead of tuning-heavy control
  • Gearbox length changes with ratio (19.5 / 25.3 / 31 / 36.8 mm) to match strict installation envelopes
  • Rated load current stays consistent across ratios, which helps size the driver more predictably
  • Power level is fixed at 8.0W in the provided configurations, supporting stable planning across variants

Why Choose us

SLW Motor Highlights

  • Ratio-to-Length Selection Logic

    This platform does not only change output speed by ratio—it also changes gearbox length. That makes it suitable when your enclosure has a hard stop on allowable gearbox length.

  • Low-Voltage Output Planning

    Because it targets 3–12V systems, you can align ratio choice with your available supply and driver constraints while keeping the mechanical package compact.

  • Torque Steps That Scale With Reduction

    The rated torque and stall torque rise clearly as ratio increases, which helps you choose a ratio based on required load margin rather than guessing.

  • Fixed Power Level for Variant Planning

    The listed configurations hold power at 8.0W, making it easier to keep performance expectations consistent while you switch ratios for different SKUs.

Custom

Beyond the Standard: Performance Customized

  • 01
    Ratio-to-Gearbox-Length Envelope
    We confirm your maximum allowable gearbox length first, then narrow the ratio group that physically fits before you commit to output speed targets.
  • 02
    Output Speed Target Mapping
    Tell us the output RPM you need. We map it to the nearest ratio option so your design hits the target without relying on extreme PWM scaling.
  • 03
    Low-Voltage Driver Compatibility Review
    We align the motor and ratio choice with your available driver capability so startup behavior and load transitions stay stable in a 3–12V system.
  • 04
    Load Margin Using Stall Torque as a Boundary
    If your mechanism can spike in load, we use the stall torque column as a boundary to reduce the risk of frequent stall events in real operation.
  • 05
    Variant Strategy for Multi-SKU Products
    If you plan multiple SKUs, we help you group ratios by the same gearbox-length bucket so your housing and mounts remain consistent across variants.

FAQ

Frequently Asked Questions

If you share your available space and the driven load type, we can help narrow the most suitable configuration quickly.

How do I choose the right reduction ratio quickly?
Start with the rated speed column to match your target output RPM, then confirm the rated torque provides enough margin for your real load.
Why does gearbox length change with ratio?
Higher reduction typically requires more gear stages, which increases gearbox length. This table lets you pick speed and length together.
Which options fit the shortest gearbox envelope?
The lowest ratio option lists the shortest gearbox length, so it suits the tightest installation spaces.
What should I share to confirm the best torque option quickly?
Share your supply voltage, target output speed, estimated load torque, duty cycle, and whether the mechanism can hit end-stops or jam.
Is this suitable for repeat production across variants?
Yes. You can hold the same motor platform and select ratios to create output-speed steps while keeping a predictable power level.
