12mm Diameter Micro Brushed Coreless Motor With Parallel Output Shaft Gearbox

This 12mm micro brushed coreless motor uses a parallel output shaft gearbox to keep motor and output on the same direction line, helping low-profile devices transmit motion without right-angle routing on 3V–12V power.

Key Features

This model is built for inline, parallel-shaft transmission where you want a compact gearmotor that drives along the same plane, making it easier to align with sliders, racks, wheels, or belt paths.

  • Parallel output shaft layout keeps transmission inline for planar mechanisms and low-profile housings
  • Gearbox length stays fixed at 10mm across ratios, so you can change performance without changing the outer envelope
  • Ratio range (26–500) supports both moderate-speed actuation and slower, higher-torque output points
  • Low rated torque steps suit light-load motion where smooth travel matters more than heavy load carrying
  • 3V–12V range fits small battery architectures and compact DC drive boards

Why Choose us

SLW Motor Highlights

  • Inline Power Path for Planar Mechanisms

    A parallel-shaft gearbox keeps the drive direction consistent, which simplifies coupling to sliders, wheel trains, rack drives, and compact belt paths.

  • Fixed-Length Gearbox for Repeatable Packaging

    Because gearbox length remains 10mm for all ratios, enclosure and mounting clearance can stay unchanged while you adjust output behavior.

  • Ratio Choices That Favor Smooth Travel

    This ratio ladder helps you tune the motor toward smoother motion at controlled speeds, useful when the mechanism benefits from stable travel rather than fast bursts.

  • Momentary Torque Data for Boundary Checks

    Momentary tolerance torque helps you estimate survivability when friction spikes occur, such as during initial break-in or when the mechanism is lightly obstructed.

Custom

Beyond the Standard: Performance Customized

  • 01
    Coupling and Alignment Strategy for Inline Loads
    We review how your coupler, gear, belt pulley, or rack interface loads the shaft so alignment stays stable and side-load does not become the main wear driver.
  • 02
    Travel-Speed Tuning for Linear or Wheel Drives
    We pick ratio based on your target travel speed at the output, then validate rated torque to keep motion smooth without relying on extreme PWM throttling.
  • 03
    Low-Profile Housing Fit Confirmation
    We confirm the 24×10×9 gearbox envelope against your cavity so you can keep the assembly flat and avoid stacked clearances.
  • 04
    Friction Spike Margin for Sliding Mechanisms
    For sliders or guides with variable friction, we evaluate your peak resistance against the momentary tolerance torque window to reduce shock stress risk.
  • 05
    Direction-of-Rotation Fit for Mechanism Layout
    We confirm your required rotation direction and mechanical routing so the gearbox orientation supports the assembly sequence and avoids reverse-linkage redesign.

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 is a parallel output shaft gearbox a better choice than a 90-degree gearbox?
Choose parallel output when your mechanism transmits motion in the same plane and you want an inline coupling path without turning the output direction.
Does changing reduction ratio change the gearbox length?
No. Gearbox length stays at 10mm across all listed ratios, which helps keep packaging consistent.
How should I choose a ratio for linear travel or wheel drive?
Use the rated speed row to match your target output RPM, then confirm rated torque meets your load and friction level.
What should I use momentary tolerance torque for?
Use it as a boundary reference for brief friction spikes, end-stop contact, or short stalls that may occur during operation.
Is this suitable for small battery-powered devices?
Yes. It supports 3V–12V supply architectures and is designed for compact integration.
