Find a replacement motor by model number

Enter the model or part number printed on the label of your old tubular motor. We look it up and list current motors whose published torque, speed, diameter and supply are within our tolerances.

Your motor

Wistar motor WSERD30-L · 1.5 Nm · 20 rpm

  • Torque 1.5 Nm
  • Speed 20 rpm
  • Diameter 25 mm
  • Voltage 12 V

Replacement suggestions compare published specifications. They do not guarantee fit or compatibility. Check the motor head, crown and drive adapters, brackets, wiring and remote pairing with the manufacturer or a qualified installer before ordering. Mains-powered motors must be connected by a qualified electrician.

Same series, current models

Current models of the same series whose published values pass the tolerance table.

OpenAxia comparison of published specifications — not a manufacturer statement

Match with changesWithin the hard tolerances, but at least one difference has a consequence, such as new remotes or a different way of setting limits. Each difference is listed.

22 other motors could not be checked (missing diameter, speed, supply voltage, torque). See them in the catalog →

6 other motors were left out: outside a hard limit of the tolerance table (for example less torque or another diameter) or no longer listed by the manufacturer.

How to read the motor label

  1. The label is on the motor head, the end that stays outside the tube, and on the cable.
  2. The model is usually printed next to the torque in Nm and the speed in rpm, for example 10/17 means 10 Nm and 17 rpm.
  3. Copy the model exactly as printed, with or without spaces and slashes.

Examples: Becker R8/17 C01 · Somfy Oximo RTS 10/17 · A-OK AM35-6/28
