A dc brushed motor — also called a PMDC motor — pairs a permanent-magnet stator with a brush-and-commutator rotor, so it runs on direct current with no external drive electronics. It costs less to build and control than a brushless equivalent, which is why this permanent magnet dc motor family remains the default choice for OEM assemblies where budget, simple two-wire drive, and short lead time matter more than a brush-free service life.
A dc brush motor runs directly from a battery or a basic H-bridge, cutting BOM cost against commutation electronics.
Every pmdc motor batch passes incoming inspection, in-process testing, and final verification before it ships, so dimensional and performance drift stays low across a production run.
We have built for OEM/ODM buyers for 15+ years, including projects for Japanese manufacturing clients, backed by ISO 9001:2015, RoHS, and Halogen-Free documentation.
Our 2,400 m² Shenzhen facility and 56+ staff mean you are quoting against the manufacturer, not a reseller markup.
SLW Motor's brushed line is a micro DC motor catalog: twelve bare-motor frames from the 12mm N20 up to the 42mm 775, all permanent-magnet (PMDC) construction, and every one available paired with a spur, planetary, or worm gearbox.
| Model | Diameter | Voltage | No-Load Speed | Max-Output Torque |
|---|---|---|---|---|
| SLW-FF180-17140 | 20mm (180 frame) | 6V | 7,074 rpm | 22.5 g·cm |
| SLW-FF180-11310 | 20mm (180 frame) | 24V | 11,562 rpm | 36.7 g·cm |
Buyers needing more torque step up to a 12mm N50 Brushed Micro Gear Motor, with geared builds under high torque DC motors and DC gear motors.
In Learn More, these motors handle joint drives and end-effector actuation, where simple 2-wire control keeps wiring harnesses light.
That straightforward control scheme suits compact robotic systems that need reliable motion without complex drive electronics.
Learn MoreFor Learn More use, they drive pumps, dosing mechanisms, and diagnostic instruments that need consistent low-cost drive.
A permanent magnet dc motor keeps that drive consistent across the duty cycles these instruments demand.
Learn MoreIn Learn More products, they power smart devices and appliances where per-unit cost matters at volume.
At high production volumes, the low part count of a dc brush motor helps keep each unit affordable.
Learn MoreInside Learn More cabin and body components, they serve as small actuators and adjustment mechanisms.
These compact dc motor mini assemblies fit the tight spaces found in vehicle interiors and body panels.
Learn MoreFor Learn More machinery, they run precision equipment and automation stations on a standard DC supply.
Because they operate on standard DC supply, they integrate easily into existing automation stations.

A dc brush motor trades brush wear and a lower top-speed efficiency ceiling for a simpler, cheaper drive circuit — the opposite trade-off a brushless winding makes.
Buyers weighing a switch to brushless DC motors for wear-free operation, or an ironless-rotor coreless DC motors build for lower inertia, can compare the trade-offs in the brushed vs. brushless comparison.
SLW Motor supports flexible sample customization and stable bulk delivery from the same Shenzhen line, so you can order prototype samples first, adjust the design, then move to production once specs are confirmed.
