Geared BLDC Motor — Frequently Asked Questions.
Concise B2B-focused answers for buyers and engineers comparing geared BLDC motor suppliers.
What is a geared BLDC motor?
A geared BLDC motor combines a brushless DC motor with a gearbox to deliver higher output torque and lower output speed than a bare BLDC motor, in a package that fits real machine constraints. Common gearbox types are planetary, spur and right-angle.
What is the difference between a BLDC gear motor and a brushed DC gear motor?
A BLDC gear motor uses an electronically commutated brushless motor — longer life, higher efficiency, lower noise and easier closed-loop control. Brushed gear motors are simpler and cheaper, but brushes wear and duty-cycle tolerance is lower.
Can geared BLDC motors be customized?
Yes. We support OEM/ODM customization of voltage, power, gear ratio, output speed, torque, shaft, mounting structure, brake, encoder, cable and connector. Provide application requirements and we will recommend a matched build.
Which gearbox is best for high-torque BLDC motor applications?
Planetary gearboxes are typically chosen for high-torque applications — high torque density, low backlash, compact in-line layout. Right-angle gearboxes are used when 90-degree transmission or space matters more.
Can BLDC gear motors be used for AGV and warehouse automation?
Yes. They are widely used as AGV drive motors, sorting line drives and warehouse automation conveyor drives where 24V/48V supply, controlled torque, low noise and long duty cycle are required.
What information should I provide for a custom BLDC gear motor quote?
Voltage, power, output speed, torque, gear ratio (if known), shaft, mounting space, brake / encoder, operating environment, quantity and a short application description.
Is a brushless gear motor the same as a BLDC gear motor?
Yes. BLDC = Brushless DC, so "brushless gear motor", "BLDC gear motor" and "brushless DC gear motor" all describe the same product — a brushless DC motor coupled with a gearbox. "BLDC" is the engineering acronym; "brushless" is the plain-English shorthand most procurement teams type into a search bar. Both terms point to the same matched motor + gearbox assembly Shenghe ships as one tested unit.
What is a brushless geared motor?
Same product as a brushless gear motor or BLDC gear motor — different word order, same hardware. "Geared" (adjective before noun) is the British / European procurement vocabulary; "gear motor" (noun + noun) is the American and Asian-export form. Both describe a brushless DC motor bolted to a gearbox (planetary, spur, worm or right-angle) and supplied as one end-of-line-tested unit.
Are brushless and BLDC gear motors interchangeable?
Yes — in catalogues and RFQ language they are interchangeable. One caveat: confirm "brushless" actually means 3-phase BLDC with Hall-sensor or sensorless control. A handful of suppliers list 2-phase or single-phase brushless designs (typically very low-power fans) under "brushless", which are not equivalent to industrial BLDC gear motors. Shenghe brushless gear motors are 3-phase BLDC with Hall sensors plus optional encoder.
What is a small 3-phase brushless DC gear motor used for?
Compact (22-42mm housing, ≤100W) brushless gear motors used where space, noise and lifecycle matter more than peak torque — cobot joints (24V 30-60W planetary with encoder), lab automation (12V/24V 20-50W vibration-free), medical pumps (NSF H1 grease for peristaltic / dosing pumps) and drone gimbals. See the dedicated Small 3-Phase section above for the full table.
