A low voltage DC motor, as SLW Motor builds it, runs on 3V–24V from a battery pack or a low-voltage DC bus — not the 220V–1000V "low voltage" that industrial line-connected drives use. If you're specifying a motor for a handheld device, a battery-powered instrument, or a 12V/24V control system, this is the voltage class you're in, and SLW supplies it across brushed, brushless, coreless, and geared motor families rather than as a single product line.
A 12V DC motor sits in the middle of that band and is the most common single voltage buyers ask for, balancing torque, current draw, and battery-pack simplicity.
Brushed DC motors suit cost-sensitive designs with simple two-wire control and no driver electronics, from a 3V DC motor in a coin-cell device to a 24V unit on a control rail, such as the 12mm N20 Micro Brushed DC Motor 3V–6V.
Low voltage motors usually ship with a gearbox, since they spin fast and need reduction for usable torque, as in the 10mm Micro Brushed Motor with Gearbox.
Low-voltage BLDC trades a controller for longer service life and less electrical noise, with no brush wear to limit lifespan, as in the 24mm Brushless DC Gear Motor with Gearbox.
Coreless motors cost more but run smoother and accelerate faster, as in the 17mm DC Brushed Coreless Motor 6V–24V.
The two models below carry fully documented no-load and max-efficiency figures from the 20mm micro brushed platform, spanning the low and high ends of the 3V–24V band.
| Model | Diameter | Voltage | No-Load Speed | No-Load Current | Max-Eff. Speed | Max-Eff. Current | Max Output Torque | Stall Torque |
|---|---|---|---|---|---|---|---|---|
| SLW-FF180-17140 | 20 mm | 6V | 7,074 rpm | 0.074 A | 5,869 rpm | 0.358 A | 22.5 g·cm | up to 131.8 g·cm |
| SLW-FF180-11310 | 20 mm | 24V | 11,562 rpm | 0.047 A | 9,759 rpm | 0.252 A | 36.7 g·cm | up to 235.6 g·cm |
Overall length depends on the gearbox or shaft option, and other voltage classes exist across different frame sizes, so figures are confirmed against the specific winding and configuration requested.
Joints and small actuators commonly run at 6–24V, sharing a rail with nearby control electronics.
That shared rail keeps the low voltage dc motor and its control electronics on one supply.

Voltage, torque, speed, and power output can all be adjusted to a target spec.
Where a target voltage or torque falls outside a catalog configuration, the winding is adjusted to match as part of standard customization.
Sample-quantity orders and small-batch customization run on the same production line as bulk runs.
Quotation feedback is returned promptly once specs are confirmed, with exact MOQ and lead-time figures confirmed during quoting.
Each of these covers a different mechanical approach available across the same low-voltage electrical range: Brushed DC Motors, Brushless DC Motors, Coreless DC Motors, and Planetary Gear Motors.
A mechanical approach without brushes, covering the same low-voltage electrical range for applications that need a different drive method.
A mechanical approach with a coreless rotor, offered across the same low-voltage electrical range as the rest of our motor technologies.
