Best Performance Density

Whatever the application, the Mirmex windings provide a superior copper fill-factor, enhancing motor performance within a specified volume unit.

Mirmex Motor | custom-made

Custom Made

Diameter, length, speed, voltage… 
You have total design freedom.
No more compromise ​​because of limitations dictated by Swiss catalogues, no matter how thick.

Mirmex Motor | easy prototyping

Easy Prototyping

Getting custom-made Mirmex micromotors is painless, quick and much more affordable.

10x faster prototype manufacturing.

Mirmex Motor | consistent performances

Consistent Performances

Our manufacturing provides a higher degree of repeatability, up to each copper fiber.

This leads to higher robustness and more homogeneous product performances.

Mirmex Motor | better thermal behavior

Better Thermal Behavior

A higher fill-factor and the ability to balance all possible sources of losses (thermal, Eddy…) enable to divide thermal losses by a significant factor.

Mirmex Motor | more sustainable

More Sustainable

The Mirmex technology optimizes micro-motors and make them use less energy.

Up to less than 45% raw materials are also required.

Mirmex Motor | unique coil topologies

Unique Coil Topologies

Mirmex winding topologies are unachievable with conventional wire-winding methods.

They provide unmatched levels of performance and efficiency.

Mirmex Motor | autoclavable


Mirmex micromotors are designed to endure hundreds of autoclave cycles and can be used in harsh environments, from intra-body to industrial to sterilization.
