Worm Micro Gear Motors

Right-angle worm micro gear motors for compact mechanisms that need self-locking behavior or perpendicular output.

Target Buyer:Best for mechanisms where a coaxial gearmotor is too long or the load should resist back-driving.

ParameterSelection GuidanceBuyer Input Needed
Right-angle layoutWorm gear stages redirect output by 90 degrees for shallow lock, valve, and latch cavities.Motor direction, output shaft orientation, mounting hole references, and available height.
Back-drive behaviorSelf-locking must be validated because load, vibration, lubrication, and lead angle all matter.Holding torque, shock load, vibration condition, and back-drive pass/fail target.
Duty cycle and heatLow worm efficiency can raise current and temperature under frequent starts.Run time, rest time, stall exposure, ambient temperature, and enclosure material.
Output interfaceOutput shaft side, length, flat, thread, and gear case mounting can be customized.Shaft drawing, load point distance, and connector or lead-wire route.

CAD, Drawing, and Curve Pack

Drawing packs are prepared against the project envelope, so the site does not publish universal CAD downloads that could mislead drop-in selection.

2D outline PDF/DWG3D STEP/IGES envelopeShaft/flange drawing review

Inputs needed before release

  • Target envelope or existing motor drawing
  • Output shaft, flange, mounting, and connector constraints
  • Voltage, loaded speed, torque, duty cycle, quantity, and destination

CAD and drawing packs are released after the project envelope and confidentiality requirements are confirmed.

Commercial Scope

RFQ Pricing, Shipping, and Return Baseline

Product-family pages support engineering and sourcing decisions before a custom quotation. They do not operate as cart checkout pages with universal prices, shipping rates, or consumer return handling.

RFQ price basis
Quoted in USD after voltage, ratio, shaft, connector, validation scope, sample quantity, annual volume, destination, and trade terms are reviewed.
Quotation baseline
Commercial review baseline active from 2026-08-06; final price, lead time, and quote validity are controlled by the confirmed quotation or purchase order record.
Export shipping review
Freight cost, Incoterm, destination, packaging, and transit-time assumptions are confirmed during RFQ. This site does not publish a universal cart shipping rate for custom motors.
Custom return scope
Custom samples and production lots are not handled as consumer returns. Replacement, rework, credit, or nonconformance handling follows the confirmed quotation, purchase order, drawing revision, and inspection agreement.
Review Commercial Terms

OEM Customization Options

  • Output shaft side, length, D-cut, thread, and mounting-hole customization.
  • Worm wheel material, lubrication, and ratio review for lock or valve duty cycles.
  • Harness, connector, and label packaging for production assembly lines.
  • Back-drive resistance review with the buyer mechanism instead of a catalog claim.

Validation Evidence to Request

  • Back-drive and position-holding checks in the real load direction.
  • Repeated start-stop temperature rise and current review.
  • Noise and wear checks after lubricant and material selection.
  • Mounting fit and shaft orientation inspection before batch release.

RFQ Checklist

  1. Output direction and shaft drawing
  2. Back-drive requirement
  3. Load torque and start frequency
  4. Noise and life target

Risk Controls

  • Heat buildup from low worm efficiency: Validate duty cycle, stall time, and lubricant before production approval.

Buyer FAQ

Are worm micro gear motors always self-locking?

No. Self-locking depends on lead angle, material, lubrication, load, and vibration. We validate it against the real mechanism.
