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.

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.

Incoming and Release Inspection

Tie the approved sample to inspection checkpoints before pilot builds or repeat orders scale into batch production.

  • Loaded torque-speed-current checks before sample approval.
  • Start voltage, stall current, and thermal rise review against the real duty cycle.
  • Noise and life checks under buyer mounting conditions when the project requires them.

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Diameter class6mm-42mmDetermines whether the drive can fit inside the buyer mechanism.
Output speed5-1000 RPMConfirms whether the selected ratio can replace extra external gearing.
Prototype lead time7-15 working daysShortens engineering validation before tooling or volume sourcing.

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

  • Gear ratio, winding, magnet, and grease selection for the required load-speed point.
  • D-cut, threaded, knurled, cross-drilled, extended, or hollow-adjacent shaft reviews.
  • Custom flange, mounting holes, lead wire length, connector, and private label packaging.
  • Metal, plastic, or hybrid gear train choices for cost, life, and acoustic targets.

Validation Evidence to Request

  • Loaded torque-speed-current checks before sample approval.
  • Start voltage, stall current, and thermal rise review against the real duty cycle.
  • Noise and life checks under buyer mounting conditions when the project requires them.
  • Incoming and final inspection points locked after drawing approval.

RFQ Checklist

  1. Target OD and maximum length
  2. Rated voltage, output torque, and output speed
  3. Gear ratio or load-speed target
  4. Shaft drawing, connector, quantity, and timeline

Risk Controls

  • Gear wear under shock load: Review stall torque, duty cycle, and gear material before sample release.
  • Noise above enclosure target: Match gear train, grease, bearing, and load point before acoustic testing.

Buyer FAQ

Can you customize the shaft and flange?

Yes. D-cut, threaded, cross-drilled, knurled, extended, and custom flange versions can be reviewed from drawings.

Can you support prototype and volume production?

Yes. We can start with standard samples, then lock drawings, tooling, inspection points, and batch production.
