A right angle gear motor pairs a DC or stepper motor with a gearbox that turns the output shaft 90° from the motor's own axis, so the drive unit sits flat or sideways inside an enclosure instead of extending straight out from the motor.
In a right angle gear motor the final reduction stage is either a worm-and-wheel mesh or a 90° gear pair, so the output shaft exits perpendicular to the motor body instead of in line with it. worm gear motors
The table below outlines the core parameters of our right angle gear motor platform, covering body diameter classes, motor types, gearbox type, and mechanical output for quick engineering reference.

| 12mm coreless 90° gear motor (type 21) | 10mm gearbox, ratios 42:1–692:1: 10–167 rpm rated, 0.036–0.6 kg·cm rated, up to 9.9 kg·cm momentary |

Need a specific gear ratio, torque, or shaft length? SLW's engineers size the gearbox to that number — send the parameters through contact us for a quote.
Pick right-angle when the output needs to exit perpendicular to the motor body — flat enclosures, panel-mounted drives, or drivetrains that change direction inside the housing. If your envelope allows an in-line output instead, the same coreless platform is available as a 12mm Coreless Motor with Parallel Shaft Gearbox.
Pick a parallel (in-line) shaft when the coupling runs straight through and there's no benefit to the extra gearbox turn — it's simpler to align and typically a slightly shorter overall length.
Right-angle configurations can be adjusted on voltage, gear ratio, shaft length, and housing material to match your enclosure and load. Send your target envelope, torque, and voltage to SLW Motor's team for a quote, or start from one of the SKUs above and adjust from there.

SLW accepts orders starting from a single prototype unit for design validation, then scales into small-batch and bulk runs once the ratio and voltage are confirmed on a SKU such as the 12mm Brushed Coreless Motor with Worm Gearbox.
Typical uses include smart locks, power tools, personal care devices, robotics, and Sample builds for a right-angle configuration typically move faster than bulk orders because they reuse an existing 12mm gearbox platform rather than new tooling; exact dates are confirmed once your gear ratio and voltage are locked in at the quote stage. that need compact, responsive drives.
A coreless rotor has no iron core, so it reduces iron losses, heat, and inertia compared with a Worm gearing has an inherent self-locking ability that varies by gear ratio and load, letting the output hold position without power in many designs — but exact holding torque depends on the specific ratio and application, not a fixed catalog number..
Yes. Voltage, shaft, gearbox, connector, grease, and feedback options can be tailored to your Gear ratio changes reuse the same housing and shaft interface across a given diameter class, so they don't require new tooling — turnaround is typically handled within the standard sample quotation cycle rather than as a separate development project..
