Description du projet
Une avancée majeure pour le bobinage des micromoteurs
Le bobinage en cuivre est le composant le plus important d’un micromoteur, qui est utilisé dans de nombreux types de dispositifs, de la brosse à dents électrique aux robots industriels modernes. Malgré leur extrême importance, le mode de production de ces bobinages en cuivre n’a pas beaucoup évolué au cours de ces 40 dernières années. Ils sont soit enroulés à la main, soit produits par des machines coûteuses et complexes. Le projet MicroMotors, financé par l’UE, met au point une nouvelle méthode de production des bobinages de micromoteurs qui consiste à les imprimer sur des circuits imprimés avant de les enrouler avec une très haute précision. Cette méthode de production des bobinages présente de nombreux avantages pour les utilisateurs: les moteurs sont plus faciles et moins coûteux à prototyper. Le projet se concentrera initialement sur le marché des outils électriques chirurgicaux et dentaires.
Objectif
Micromotors are ubiquitous, used in your electric toothbrush, in your dentist’s drill and in modern industrial robots. The most important component that determines motor performance, functionality and longevity, is the copper winding, which dictates how much power a motor can generate for a given current. The way these copper windings are produced has not changed much over the last 40 years: they are either wound by hand for prototyping or for small production runs, or they are produced by expensive machines that are complex to operate, inflexible and viable only for large production runs.
Mirmex is transforming the way micromotor windings are produced: instead of winding copper wire by hand, Mirmex prints them on PCB’s before rolling them with high precision. This approach to producing windings has many user benefits: motors are easier and less costly to prototype, they are more flexible in design terms, more durable, lighter, become hot less quickly, feature higher torque and greater dynamics - and all at a lower cost than the incumbent technologies.
The go-to-market strategy will focus initially on the surgical/dental power tools segments because they care more about performance, weight and other value-added features than about price. Mirmex will then address the industrial/automotive sector and begin producing motors, in addition to windings. Demand is already strong: Mirmex has received purchase orders worth €80k for small quantities of prototype products and 8 LOIs.
In order to fully exploit the very high commercial potential of our innovation, Mirmex needs to demonstrate that (i) it is able to manufacture windings of exceptional quality in commercial volume, (ii) the products meet the stringent requirements for autoclavability from medical customers and (iii) our winding design software tool can interface with a higher number of materials and motor architectures. Mirmex then expects rapid scale-up, targeting revenues of €31.5m and EBITDA of €11.7m by 2024
