12mm Diameter 20 Micro Brushed Coreless Motor With 90 Degree Shaft Gearbox

This 12mm micro brushed coreless gear motor uses a 90-degree shaft gearbox for right-angle packaging in 3–12V systems, letting you route output sideways while keeping a defined 12V performance point for speed and torque planning.

Key Features

This model is a right-angle micro brushed coreless gear motor platform defined by its 90° output path and compact gearbox block (18×12×10), making selection straightforward when your layout cannot accept an inline shaft.

  • 3–12V applied range supports compact battery and regulated low-voltage architectures
  • 90-degree shaft gearbox converts the motor axis to a side-output, solving tight clearance and routing constraints
  • 12V rated point provides a defined baseline for speed/current/torque planning in compact mechanisms
  • No-load speed is listed as 90 ±10% rpm, helping you set expected free-run behavior before load is applied
  • Rated-load speed is listed as 68 ±10% rpm with rated-load current 320 mA, anchoring driver sizing under working load

Why Choose us

SLW Motor Highlights

  • Right-Angle Output Solves Clearance Conflicts

    The 90-degree shaft gearbox routes output sideways, which helps when your assembly cannot accommodate an inline motor length or needs a flat gearhead orientation.

  • Defined Low-Speed Working Point for Micro Drives

    Rated-load speed at 68 ±10% rpm provides a stable anchor for mechanisms that prioritize controllable low-speed motion over high RPM output.

  • Compact Gearbox Block Protects Mechanical Packaging

    The 18×12×10 mm gearbox size helps when the design has tight envelope constraints and must keep the output stage inside a small housing.

  • Load Current Anchors Driver Sizing

    Rated-load current at 320 mA defines the normal working electrical load, which helps separate routine operation from stall or jam events.

Custom

Beyond the Standard: Performance Customized

  • 01
    Right-Angle Envelope Lock-In Before Layout Freeze
    We lock the gearbox block orientation and side-output direction first, because the 90° path determines clearances, mounting faces, and wiring route in compact assemblies.
  • 02
    Output Direction and Rotation Definition for Mechanism Coordination
    We confirm CW/CCW expectations and output-side definition early so the mechanism motion matches your system logic without reversing wiring or reworking mounting.
  • 03
    Low-Speed Stability Under Rated Load
    We map your required working speed to the 68 ±10% rpm rated-load point first, then verify torque margin so the motor does not dip into stall behavior during friction spikes.
  • 04
    Stall Boundary Planning for Jam Events
    We define current limiting and recovery logic around the listed stall boundary so brief overloads do not create repeat failures in micro gear trains.
  • 05
    Voltage Window Strategy Across 3–12V Systems
    If you build multiple variants, we align the configuration to your supply rails and control method while keeping the 12V rated point as the reference baseline.

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 this motor quickly for a tight layout?
Confirm you need a 90-degree output first, then match your target working speed to the rated-load speed, and verify stall behavior fits your protection strategy.
Why does gearbox length change with ratio?
Higher reductions typically add stages. This table shows the resulting gearbox length so you can match performance without exceeding your enclosure.
What should I share so you can shortlist suitability faster?
Share your available space, required output direction, target speed, load torque estimate, duty cycle, and supply voltage.
Is it suitable for repeat production across variants?
Yes. You can standardize the right-angle gearbox platform and tune system variants mainly by voltage architecture and control settings.
