PG120BL110 Brushless Hub Planetary Gear Motor for Robot Lawn Mowers: A B2B Sourcing Guide

The global shift toward robotic and battery-powered lawn mowers has turned the drive motor into the single most decisive component in the whole machine. Buyers sourcing mower powertrains are no longer searching for "any motor" — they search for a quiet, high-torque, long-life brushless gear motor that survives wet grass, uneven terrain and years of daily mowing. The PG120BL110 brushless hub planetary gear motor was developed for exactly that job.

What Is the PG120BL110 Brushless Hub Planetary Gear Motor?

The PG120BL110 is an integrated brushless DC outrunner motor combined with a planetary gearbox, built into a compact hub format (φ39 mm * L26 mm). Because the reduction happens inside the hub, the unit delivers high torque at low speed without an external belt or chain drive. It runs from 6–30 V DC (24 V typical), delivers up to 3 N·m of torque, and can be ordered with a built-in or external driver. For lawn mower makers, this means fewer parts, a smaller footprint and a drive system that is ready to bolt straight onto the cutting deck or wheel.

Why a Brushless Hub Planetary Gear Motor for Lawn Mowers?

B2B procurement teams repeatedly shortlist brushless gear motors for the same four reasons — and each one maps directly to what end users complain about:

• Longer runtime per charge. Brushless commutation removes the brush friction that wastes energy in brushed motors, so a given battery pack mows more square meters.
• High torque in a small hub. The planetary stage multiplies torque close to the load, giving the blade and wheels the authority to push through thick, damp grass.
• Quiet operation. At ≤55 dB the motor keeps robotic mowers neighbour-friendly — a top-three purchase driver in the EU and North America.
• Long service life & low maintenance. No brushes to replace, sealed construction and a −40 °C to +60 °C range mean fewer field failures and lower warranty cost.

What B2B Buyers Look For: A Sourcing Checklist

If you are evaluating suppliers of brushless hub motors for lawn mowers, run every offer through this list:

1. Torque & speed at the duty point, not just the peak figure — confirm the rated torque at your mowing RPM.
2. Driver integration — built-in or external driver, and whether it supports your controller protocol.
3. Dimension & mounting fit — hub diameter, shaft type (D-cut, flat, threaded) and cable exit.
4. IP rating & sealing for wet-grass and wash-down environments.
5. Certifications — RoHS, CE, ISO and IATF 16949 signal process control for automotive-grade reliability.
6. Sample lead time and MOQ — how fast you can validate a prototype before committing to volume.
7. Customization — voltage, speed, torque, shaft and logo branding.

Typical Applications

Beyond robot and push lawn mowers, the PG120BL110 platform is used in robotic vacuums and sweeping robots, electric wheelchairs, smart-home appliances, power tools, medical and precision instruments, and automotive electronics. Its quiet, high-torque profile makes it equally suitable for range hoods, dishwashers and automatic door or lock mechanisms.

Customization & OEM Options

• Voltage, rated speed and torque tuned to your duty cycle
• Shaft geometry: D-cut, flat, round, with hole, or fully custom
• Built-in or external driver configurations
• Logo printing and private-label packaging
• Carton packaging (≈12 pcs/box) or customized

Frequently Asked Questions

What is the MOQ for the PG120BL110?

The standard MOQ is 1,000 pieces, but it stays flexible for simpler builds and off-season schedules — talk to our team about your project.

Can I get samples before placing a volume order?

Yes. We ship samples via UPS, TNT, FedEx or DHL so you can validate torque, noise and fit before mass production.

What is the delivery time?

Standard delivery is 3–5 working weeks; in peak season larger volumes may take longer, and expedited production is available for urgent orders.

Can you print our logo on the motor?

Absolutely — most of our motors are customizable, including logo labeling on the housing.
