Key Features

This model pairs a coreless BLDC rotor with a planetary gearbox to deliver stable torque in a compact envelope, while keeping control and wiring integration straightforward for OEM assemblies.

  • Brushless coreless design supports efficient operation and low mechanical drag
  • Planetary gearbox provides a ratio ladder for controlled speed reduction and torque build-up
  • 12V–24V supply range fits common industrial and battery-powered architectures
  • Pre-matched speed–torque steps simplify selection across multiple reduction ratios
  • Harness-style output supports cleaner integration in compact enclosures

Why Choose us

SLW Motor Highlights

  • Ratio Ladder That Matches Real Selection Work

    Multiple reduction options let you pick the speed and torque step that fits your mechanism, instead of forcing a single compromise point.

  • Efficient Coreless BLDC for Smooth Low-Speed Control

    Coreless BLDC behavior helps when you need steady motion at low speed and want to reduce heat build-up under continuous operation.

  • Gearbox Length Visibility for Packaging Decisions

    Gearbox length varies by ratio, so you can select performance while keeping the assembly inside a known envelope.

  • Harness-Friendly Integration for OEM Assemblies

    Connector-style wiring supports cleaner routing in compact housings and reduces assembly variability during integration.

Custom

Beyond the Standard: Performance Customized

  • 01
    Harness and Connector Mapping Review
    Wire grouping, connector type, and pin assignment can be reviewed to match your controller layout and reduce rework during wiring.
  • 02
    Ratio-to-Length Envelope Selection
    We help narrow the ratio range that meets your output requirement while respecting the gearbox length window shown in the data table.
  • 03
    Backlash and Motion Feel Targeting
    If your application is sensitive to position feel, we review gearbox stage choice and operating point to manage perceived backlash and motion smoothness.
  • 04
    Short-Duty Torque Margin Check
    For intermittent peak load, we evaluate the momentary tolerance torque range against your duty pattern to avoid thermal or gear stress issues.
  • 05
    Voltage and Driver Compatibility Planning
    12V–24V integration is evaluated around your driver type, sensor needs, and control strategy so the motor behaves predictably in your system.

FAQ

Frequently Asked Questions

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

What makes this motor different from a brushed gear motor option?
It uses a brushless coreless motor, which supports smoother control and typically reduces mechanical wear points compared with brushed designs.
How do I choose the right reduction ratio from the table?
Start from your required output speed, then check the rated torque at that ratio and confirm the gearbox length fits your available space.
Why does gearbox length change with ratio?
Higher ratios typically use additional stages, which changes the gearbox stack length and impacts packaging.
Is this model suitable for continuous running?
Yes, it is designed for stable operation, but final suitability depends on your load, duty cycle, and cooling conditions.
Can you support a specific connector or wiring route?
Yes. We can review wiring exit direction and connector style to match your enclosure routing.
