Questions from OEM buyers

How do I request an OEM quotation for N20?

Send the complete assembly or configuration code, supply voltage, reduction ratio, loaded output speed and torque, duty cycle, mounting drawing and expected quantity. Include the output shaft and any required control interface.

Can I select this series by its name alone?

Use the complete assembly code, reduction ratio and matching drawing. A series can include different motor windings, gear ratios, shaft details and mounting arrangements; confirm the selected version and output working point.

What should be checked before a production order?

Confirm the selected model code, drawing revision and acceptance requirements, then evaluate the sample in the intended equipment and operating conditions.

Bring us the motor requirement for your next product.

Send your preferred model or the working point, installation drawing and expected quantity.

  • Supply voltage, loaded speed and torque
  • Shaft, mounting and installation requirements
  • Sample quantity and expected project demand

A drawing, reference motor or application brief is a useful starting point.
