37mm Diameter Brushless DC Motor With Gearbox

This 37mm brushless DC gear motor targets higher-load drives where current headroom, stronger torque steps, and a clear ratio ladder help you stabilize output under real resistance.

Key Features

This model focuses on higher power and higher load current behavior compared with smaller BLDC gear motors, making it a practical choice when the mechanism cannot “coast through” resistance changes.

  • Higher output class shown by the rated load power level in the data table
  • High current headroom supports load spikes and frequent start-stop duty profiles
  • Wide reduction ratio coverage (15.5 to 896) supports both medium-speed drive and very low-speed high-torque output
  • Torque steps rise clearly with ratio, making selection more mechanical and less trial-based
  • Gearbox envelope is fixed in the product definition, helping you keep a stable assembly interface while selecting ratios

Why Choose us

SLW Motor Highlights

  • Higher Load-Class Planning From the Start

    This table shows a higher rated load current and a higher power level, which makes this model more suitable when the mechanism regularly operates under real resistance.

  • Torque Steps Built for Load, Not Only Speed

    Torque rises strongly as ratio increases. That helps you select based on load margin instead of selecting by output RPM only.

  • Stall Boundary That Helps You Protect the System

    Stall torque and stall current give a clear boundary for driver sizing and overload protection strategy.

  • Wide Ratio Ladder for Variant Building

    The ratio set supports multiple output behaviors while keeping the same motor platform, which helps when you build multiple SKUs.

Custom

Beyond the Standard: Performance Customized

  • 01
    High-Load Driver Matching Strategy
    We match the option to your driver capability using rated load and stall current so the controller remains stable under load peaks.
  • 02
    Start-Stop Duty Profile Calibration
    If your application starts and stops frequently, we narrow ratios based on how quickly torque must build without overheating the system.
  • 03
    Output Speed Selection Without Over-Scaling PWM
    We map your target output RPM to the ratio ladder so you avoid relying on extreme PWM scaling to hit speed targets.
  • 04
    Overload Boundary Definition by Stall Data
    We use stall torque and stall current to define a practical overload boundary for protection settings and mechanical safety margin.
  • 05
    Ratio Pairing for Multi-SKU Lineups
    We help you choose two to four ratio anchors that cover your product lineup while keeping the same assembly concept and wiring routing.

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 37mm gear motor different from smaller BLDC gear motors?
It targets higher load behavior with higher current headroom and a higher power level in the provided configurations.
How do I choose the right ratio quickly?
Start with the rated speed column to match your target output RPM, then confirm rated torque provides enough load margin.
Why should I care about stall current?
Stall current guides driver selection and protection settings, especially in mechanisms that can jam or see sudden load spikes.
Can I use this in wide-voltage systems?
The product definition lists 6V to 48V as the applied range. Share your actual supply range so we can narrow a suitable configuration.
Is this suitable for repeat production?
Yes. The ratio ladder supports repeatable variants while keeping the same motor platform.
