Belgium-based Mirmex Motor is at the forefront of a significant innovation in electric micromotor technology, introducing a proprietary approach to manufacturing power-dense windings that promises to redefine performance benchmarks across various high-precision applications. Unveiling their advancements at the recent MD&M West exhibition, Mirmex Motor demonstrated how their printed circuit technology yields motors that are not only remarkably more compact and dynamic but also significantly more energy-efficient than their conventionally wound counterparts. This paradigm shift in motor design addresses long-standing challenges in manufacturing, efficiency, and application-specific optimization, setting a new standard for micromotors in critical sectors such as medical devices, aerospace, and robotics.
The Genesis of a Revolution: Mirmex Motor’s Printed Winding Technology
At the heart of Mirmex Motor’s innovation lies its unique method of producing windings for electric motors, departing radically from traditional copper-wire coiling. Instead of intricate winding processes, Mirmex employs advanced manufacturing techniques to print highly optimized conductor patterns onto flexible circuit board strips. This method, driven by sophisticated AI algorithms, allows for the creation of winding geometries previously deemed impossible or impractical with conventional methods. The result is a series of motors that are 50% more compact and exhibit 70% greater dynamism compared to comparable slotless motors utilizing traditional copper-wire windings. Crucially, this enhanced performance comes with a threefold reduction in heat waste, a critical factor for extending lifespan, improving reliability, and reducing energy consumption in power-sensitive applications.
Francisco Diaz of Mirmex Motor, speaking at MD&M West, highlighted the versatility of their offerings. Mirmex provides a range of products including bare windings, stators, as well as frameless and fully assembled motors, available in both radial and axial-flux architectures. This modularity allows original equipment manufacturers (OEMs) unprecedented flexibility in integrating Mirmex’s technology into their designs, whether they require components for custom motor builds or complete, ready-to-deploy units. The flexibility in architecture further broadens the scope of application, catering to diverse spatial and performance requirements.
Addressing the Limitations of Traditional Motor Manufacturing
The conventional manufacturing of electric motor windings has long been a bottleneck in the pursuit of greater efficiency and miniaturization. Traditional motors rely on copper windings that are notoriously challenging to produce, especially for micromotor applications where precision is paramount. The process often involves intricate coiling of fine copper wires, a task that, particularly during prototyping phases, frequently necessitates manual assembly. This hands-on approach is not only labor-intensive but also prone to inconsistencies, impacting overall motor performance and scalability.
Moving from prototyping to full-scale production introduces another set of challenges. Manufacturers typically invest in expensive and specialized machinery designed for winding specific coil patterns. These dedicated machines, while efficient for high-volume production of a single design, are often inflexible. Any modification to the motor’s specifications—even minor adjustments to winding parameters—can require significant retooling or the acquisition of new machinery, leading to substantial capital expenditure and extended lead times. Furthermore, the inherent physical constraints of wire winding limit the complexity and optimization of the resulting magnetic fields, often leading to compromises in power density and thermal management. The "slotless" motor design, while offering advantages in smoother operation and reduced cogging torque, still grapples with the limitations imposed by conventional copper-wire windings, particularly regarding thermal dissipation and the achievable fill factor within the motor’s volume.
Mirmex Motor’s printed winding technology offers a compelling contrast. By leveraging AI algorithms, the design of winding patterns transcends the physical limitations of wire winding. These patterns are then precisely printed onto flexible circuit board strips. For axial-flux architectures, these strips are laid flat, while for radial architectures, they are ingeniously closed into a tube. This automated manufacturing and validation process eliminates the need for manual winding, significantly reducing production costs, enhancing consistency, and accelerating prototyping cycles. The ability to vary conductor sizes, thicknesses, interconnections, and even the fundamental pattern itself allows for unparalleled optimization. Each winding can be meticulously tailored to specific application requirements, environmental conditions, and operational constraints, thereby maximizing efficiency, power density, and thermal performance for a given task. This level of customization and automation represents a significant leap forward in electric motor manufacturing, promising to democratize access to high-performance micromotors for a broader range of industries.
