Micro BLDC Gear Motors

Micro brushless gear motors combining compact planetary or spur gearboxes with BLDC efficiency for high-torque, low-speed actuation.

Target Buyer:For automation and actuator engineers who need high torque at low speeds without the wear issues of brushed gear motors.
Micro Brushless Planetary Gear Motor

Controlled technical documents

Request datasheet, CAD, and validation scope for Micro BLDC Gear Motors

Public generic files can mislead OEM selection when winding, bearing, connector, test fixture, or acceptance criteria are still open. Technical documents are shared after model, revision, NDA, test condition, and destination scope are confirmed.

Request by WhatsAppSend full RFQ

No placeholder certificates, stock proof photos, or generic public CAD downloads are published from this request block.

Datasheet fit check

Voltage, speed, torque, current, thermal, and life targets.

CAD or drawing review

Shaft, flange, connector, cable, and assembly interface.

Validation evidence scope

Noise, load, vibration, endurance, and inspection records.

Capability Highlights

  • Integrated planetary and spur gearheads for maximum torque density
  • Long-life brushless driving combined with durable gear trains
  • Custom gear ratios, shaft profiles, and lubrication options

Typical Applications

  • Robotic joints and grippers
  • Smart locks and access control
  • Medical dosing mechanisms
  • Precision dispensing pumps

Engineering Focus

  • Balance motor speed and gear ratio against target output torque
  • Review radial and axial load capacity of the gearbox output shaft
  • Select lubrication and gear material based on duty cycle and noise limits

Buyer Decision Notes

Best-fit buyer

For automation and actuator engineers who need high torque at low speeds without the wear issues of brushed gear motors.

Validate Before Sampling

  • Balance motor speed and gear ratio against target output torque
  • Review radial and axial load capacity of the gearbox output shaft

RFQ Data That Changes the Quote

  • Output speed (RPM) and output torque requirements
  • Gearbox type (planetary/spur) and maximum diameter limit
  • Radial and axial load applied to the shaft

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Gearbox Backlash1° to 3° for planetary, < 10 arc-min for precisionCritical for trajectory precision in robotic joints and repeatability in medical dosing.
Mechanical Efficiency ($eta$)90% (1-stage) dropping to 60% (4-stage)Directly determines the motor continuous torque required to reach the target output payload.
Output bearing loadRadial and axial load checked against shaft, gearhead, and duty cycleSide load can shorten gearbox and bearing life even when torque looks acceptable.

RFQ Checklist

  1. Output speed (RPM) and output torque requirements
  2. Gearbox type (planetary/spur) and maximum diameter limit
  3. Radial and axial load applied to the shaft
  4. Backlash tolerance, noise limit, and lifetime cycles

Risk Controls

  • Stripped planetary gears from emergency stops: Evaluate the Maximum Permissible Dynamic Torque of the gearbox, not just the motor stall torque.
  • Inadequate voltage margin at peak load: Select a motor KV that provides 20-30% extra No-Load RPM to compensate for voltage droop and PWM limits.

Requestable Evidence Pack

Ask for proof tied to the exact test condition

Use this evidence package to keep motor claims connected to load, fixture, controller, drawing revision, and acceptance criteria before sampling or production release.

RFQ note

Do not treat quiet, long-life, efficient, or compliant as a generic claim. Confirm the measured condition, buyer fixture, sample lot, and acceptance rule for this program.

Buyer FAQ

Do you assemble the gearbox and BLDC motor in-house?

We can review motor-plus-gearbox assemblies and define the test scope around output speed, torque, backlash, load, duty cycle, and acceptance criteria before pilot supply.

What data is needed to size a micro BLDC gear motor?

Provide output speed, continuous torque, peak torque, duty cycle, backlash target, radial and axial load, package limit, voltage, feedback, and lifetime cycles.
