Overview

One Modular Platform.
Sixteen Standard Models.

Sixteen frame and length combinations cover a stall torque range from 0.24 Nm to 75 Nm — and every one of them can be re-specified around your axis: shafts, flanges, housings, windings and connections.

The slotless stator is the defining feature. Without stator slots there is no reluctance variation, so the motor turns without detent steps: zero cogging and minimal torque ripple, with high speed, torque, efficiency and rigidity.

Why This Series

What the Xtrafors Prime
Gives Your Axis

The properties the Xtrafors Prime was designed around — taken from the Mavilor documentation, not from a brochure adjective list.

  • Zero Cogging

    The slotless stator removes the reluctance variation behind cogging torque — no detent steps.

  • Minimal Torque Ripple

    Smooth torque through the whole revolution, for force-loop and low-speed positioning axes.

  • High Speed and High Torque

    0.24 Nm to 75 Nm stall torque — 3 000 rpm rated up to 13.2 Nm, 1 500 rpm above it.

  • High Efficiency

    Less loss in the magnetic circuit, less heat to take out of the machine.

  • High Rigidity

    A stiff mechanical design that holds its position under load.

  • Modular Construction

    One platform, sixteen standard models — shafts, flanges, housings, windings and connections customized on top.
