Brushless DC Motors (BLDC)

A brushless DC motor (BLDC motor) replaces the brushes and commutator of a conventional DC motor with electronic commutation, so there is no sliding contact to wear out. SLW Motor manufactures brushless DC motors from 16mm to 60mm in diameter — bare BLDC motors, brushless coreless motors, and BLDC gear motors paired with planetary or worm gearboxes — built in-house at our Shenzhen factory as a direct BLDC motor manufacturer, with 15+ years of R&D experience and clients across 30+ countries.

Advantages

Why Source Your Brushless DC Motors From SLW Motor

In-house winding, gearbox production, and engineering support keep your brushless DC motor program moving from prototype to volume.

  • In-House Winding and Gearbox

    Motor and gearbox are built and matched under one roof, not sourced separately and mated after the fact.

  • 15+ Years of Engineering

    Engineering experience includes work for Japanese manufacturing customers, where dimensional consistency requirements run tight.

  • 30+ Countries Served

    Buyers span medical, automation, robotics, and precision equipment markets across more than 30 countries.

  • OEM/ODM Flexibility

    Start from a catalog configuration or specify a fully custom build; both run through the same production line.

  • ISO 9001:2015 Certified

    ISO 9001:2015 certification is in place, with RoHS and Halogen-Free reporting available on request.

For a lower-cost build without electronic commutation, brushed DC motors span the overlapping 12–42mm size classes, trading electronic commutation for brush wear over time; the full catalog of DC gear motors lists every motor and gearbox family side by side.

Specifications

Specifications & Customization

Voltage, speed, torque, and gear ratio shift with winding and gearbox selection, so brushless DC motors are configured per platform rather than sold to one fixed spec. Reference figures from the catalog datasheets:

Options

Customization Options

Every brushless dc motor build can be adjusted along several axes before it goes into production.

  • Performance

    Torque, speed, voltage, and power are tuned to the driven load.

  • Transmission

    Planetary, spur, or worm gearboxes, or plastic gear trains for lighter-duty mechanisms.

  • Materials

    Brass, stainless steel, powder-metallurgy alloys, or engineering plastics for housings and gears.

  • Operating Conditions

    Quiet operation, extended life-cycle targets, and temperature-resistant builds for harsh environments.

  • Value-Added Integration

    Hall sensor or encoder feedback, PCB soldering, and wire harness assembly, so the motor arrives ready to wire in.

FAQ

FAQ

Answers on how a brushless dc motor works, what it needs to run, and how SLW Motor handles sizing, samples, tooling, and shipping.

Brushless DC motor vs brushed DC motor?
A brushed motor switches current mechanically through carbon brushes and a commutator; a brushless DC motor switches it electronically through a driver, with no sliding contact.
Does a BLDC motor need a controller?
Yes. Every brushless DC motor needs an electronic driver (ESC) to commutate its windings and cannot run directly from a battery the way a brushed motor can.
What size brushless DC motors does SLW Motor make?
The BLDC line runs from 16mm coreless brushless motors up to 60mm frames, in 12V, 18V, and 24V windings across a 6–48V applied range, as bare motors or with gearboxes.
Is there a minimum order quantity (MOQ)?
SLW Motor does not publish a fixed MOQ. Sample runs and small-batch customization are supported alongside stable bulk production, with batch size confirmed during quoting.
How long does a sample take?
Sample timing depends on whether the build is a catalog configuration or a custom design. Production runs on optimized scheduling with strict process control; confirm timing at quote.
Is there a tooling cost for custom builds?
Tooling cost, when required, depends on the customization scope — custom housings, shafts, or connector integration typically involve tooling, while catalog configurations do not.
How long does full customization take?
Timeline scales with scope — winding changes, gearbox pairing, and encoder or PCB integration each add engineering steps. Inquiry replies and quotation feedback come back promptly.
What shipping terms apply?
Shipping terms are confirmed per order based on destination, order size, and configuration. Contact SLW Motor directly to arrange terms for your specific shipment.
