Key Features

This model uses a 36mm BLDC motor paired with a multi-stage planetary gearbox, targeting applications that sit between compact drives and heavy-duty worm gear solutions.

  • Higher power density platform compared with smaller BLDC gear motors in the same family
  • Planetary gearbox architecture balances torque scaling and rotational smoothness across ratios
  • Wide reduction range (3.7 to 721) supports both moderate-speed and very low-speed output needs
  • Gearbox length grouped by ratio bands, helping maintain enclosure consistency across variants
  • 24V rated data shown for stable system planning in industrial and commercial power architectures

Why Choose us

SLW Motor Highlights

  • Higher Torque Ceiling Without Worm Gear Tradeoffs

    This platform fills the gap between compact planetary gear motors and worm gear systems, offering higher torque without the friction and efficiency loss typical of worm drives.

  • Planetary Smoothness Under Load

    Multi-stage planetary gears help keep rotation smooth as torque increases, which benefits motion systems that still require controlled speed.

  • Ratio Bands That Define Mechanical Capability

    Each ratio band changes not only speed, but also gearbox length and torque envelope, allowing mechanical behavior to be selected at the design stage.

  • Rigid Gearbox Housing for Load Stability

    The larger gearbox body improves alignment and stiffness when operating under higher torque compared with smaller BLDC gear motors.

Custom

Beyond the Standard: Performance Customized

  • 01
    Torque Class Selection by Ratio Band
    We help you choose a ratio band based on the torque class your mechanism truly needs, avoiding both under-sizing and unnecessary gearbox length.
  • 02
    Gearbox Length Commitment Point
    Once a gearbox length band is chosen, we lock compatible ratios early so enclosure, mounts, and wiring paths stay consistent.
  • 03
    Load Transition Behavior Review
    We evaluate how torque ramps during startup and speed changes so the motor remains controllable under varying load conditions.
  • 04
    Driver Headroom at Higher Torque Levels
    As torque increases, current behavior matters more. We align ratio choice with driver headroom to avoid instability or thermal stress.
  • 05
    Platform Positioning Within a Product Line
    For multi-size product families, we help define where this 36mm platform sits relative to smaller or worm-gear solutions, keeping selection logic clear.

FAQ

Frequently Asked Questions

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

When should I choose this 36mm planetary motor instead of a smaller BLDC gear motor?
Choose it when your torque requirement starts to exceed what smaller planetary platforms can deliver reliably.
When is a worm gearbox still a better option?
Worm gearboxes are better for extreme reduction and holding behavior. This model favors torque delivery with smoother rotation.
How do I narrow ratios quickly?
Start with your target output speed, then confirm rated torque and gearbox length fit your mechanical envelope.
What information helps confirm suitability fastest?
Share supply voltage, target output speed, required torque, duty cycle, and maximum allowable gearbox length.
Is this suitable for repeat production?
Yes. Ratio bands and gearbox length grouping support consistent variant planning.
