AI-developed smallest micromotors and flexible circuits provide manufacturing efficiency and design excellence

Constructed using flexible substrates and developed with artificial intelligence (AI), these micromotors deliver unmatched performance and exceptional precision. Compared to conventional solutions based on wire windings, they can be: - up to 50% mor

Industrial start-ups in Europe often face significant challenges. For this reason, every success story is worth celebrating. Originating as a spin off from UCLouvain after more than a decade of research starting in 2013, Mirmex has emerged as a pioneering industrial player in mechatronics. The company introduces a novel method for manufacturing high power density electric micromotor windings.
After extensive research and development, this breakthrough technology is now commercially available and has the potential to fundamentally transform traditional winding design and manufacturing.
A new approach to motor design
Designed for high performance applications such as industrial tools, surgical systems, optics positioning, aerospace, and robotics, Mirmex motors are fully customizable thanks to proprietary software developed in house.
Unlike conventional motors that rely on wound copper wire, Mirmex uses a flexible substrate on which the winding pattern is printed. This substrate is then formed into a hollow cylindrical structure, creating the motor winding.
As a result of its research, Mirmex Motor has developed an automated process for creating winding topologies and validated the use of flexible materials for patterns that are difficult or impossible to reproduce using traditional methods. The coils made on these flexible substrates provide strong performance improvements to the motors in which they are used.

These patterns offer possibilities that go beyond the shape of the windings. By varying the size, pattern, thickness, or interconnections of the conductors, the coils can be adapted to specific requirements. The design of the ideal motor depends on its use, environment, and constraints, and the Mirmex Motor software enables optimization on a case by case basis.
This significantly increases the possibilities for performance optimization and design flexibility. Mirmex not only offers high performance density but also flexibility in adapting to customer requirements. In many cases, engineers struggle to find the ideal motor solution, as standard catalog motors are designed to fit a wide range of applications rather than being optimized for a specific use case. This is where Mirmex differentiates itself: by offering higher performance per unit volume and a high degree of flexibility, enabling solutions that better match the system requirements.
A step-change in performance and flexibility
With Mirmex, there is no need to compromise on motor design. Instead of adapting the system to the motor, the motor can be adapted to the system. The performance gap between standard catalog motors and fully optimized solutions is often underestimated, but Mirmex aims to consistently provide an optimized solution tailored to the application.
In addition, the technology is agnostic to the motor topology and can be implemented in radial flux designs, flat motors, and linear motors, among others. It can be supplied as stators, frameless motors, or fully assembled motors, offering a flexible approach depending on customer needs. Mirmex does not only provide motors but also a highly adaptable business model to support different integration approaches.

Conclusion
Mirmex is a fast growing scale up originating from a strong research environment. The company addresses challenges related to motor winding design and production while enabling more compact, higher performance, energy efficient, and precise solutions.
Beyond performance improvements, the key advantage lies in the ability to adapt the motor to the specific application, rather than relying on standardized designs. This allows customers to achieve better integration and overall system performance.
This creates a clear opportunity to develop more competitive products and differentiate in demanding applications.
