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.

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

  • Voltage, ratio, no-load and loaded RPM matching from a reference N20 motor.
  • D-cut, shaft length, gear case, mounting hole, wire length, connector, and polarity changes.
  • Encoder, Hall, or low-noise tuning review when compact devices need feedback or quieter operation.
  • Sample matching and drawing lock before moving from replacement sourcing to production.

Validation Evidence to Request

  • Loaded RPM, torque, current, and start-voltage comparison with the reference motor.
  • Shaft, connector, polarity, and mounting inspection for drop-in replacement projects.
  • Noise and thermal checks inside locks, meters, valves, or small modules.
  • Batch inspection limits after buyer sample approval.

RFQ Checklist

  1. Rated voltage and loaded output speed
  2. Required torque at the load point
  3. Gear ratio or reference motor code
  4. Shaft drawing, wire length, connector, and quantity forecast

Risk Controls

  • Selecting from no-load RPM only: Compare loaded speed, torque, current, and duty cycle before approving samples.
  • Shaft mismatch during drop-in replacement: Confirm D-cut position, shaft length, connector, and mounting hole references from drawings.

Buyer FAQ

Can you match an existing N20 gear motor sample?

Yes. Send the sample code, photos, voltage, ratio or RPM, shaft dimensions, and target quantity for review.

Can N20 motors include encoders?

Encoder versions can be reviewed when the buyer provides resolution, signal type, cable length, and controller interface.
