Belgium-based Mirmex Motor has introduced a groundbreaking proprietary approach to manufacturing power-dense windings for electric micromotors, a development poised to significantly impact various high-precision industries. The core of their innovation lies in printed circuit technology, which yields motors that are reported to be 50% more compact and 70% more dynamic than comparable slotless motors relying on conventional copper-wire windings. This advancement also boasts a threefold reduction in heat waste, addressing a critical challenge in high-performance motor design. The company showcased this transformative technology at the recent MD&M West event, drawing considerable attention from industry professionals.
A Paradigm Shift in Micromotor Design and Manufacturing
The traditional landscape of electric motor manufacturing, particularly for micromotors, has long been characterized by intricate and often labor-intensive processes. Conventional slotless motors, while offering certain advantages over slotted designs in terms of smoother operation and reduced cogging torque, still rely on complex copper-wire windings. These windings are notoriously challenging to produce, demanding precision and often extensive manual assembly during prototyping phases. For full-scale production, manufacturers typically invest in specialized, expensive, and often inflexible machinery tailored to specific coil designs, leading to significant capital expenditure and limited adaptability. This conventional approach can hinder rapid iteration, increase lead times, and constrain design innovation, especially for applications demanding extreme miniaturization and performance.
Mirmex Motor’s technology directly confronts these limitations by reimagining the very foundation of motor windings. Instead of winding individual copper wires, their method involves designing and printing these windings onto flexible circuit boards. This fundamental shift from additive winding to subtractive printing offers unprecedented control over the winding geometry, density, and material distribution. The result is a motor architecture that transcends the physical constraints of traditional winding techniques, enabling designs previously deemed impossible or impractical. The reported gains in compactness, dynamism, and thermal efficiency are not merely incremental improvements but represent a significant leap forward, potentially redefining the performance benchmarks for electric micromotors.
Unpacking the Technological Advantage: AI-Driven Printed Windings
At the heart of Mirmex Motor’s innovation is a sophisticated integration of artificial intelligence (AI) with advanced manufacturing processes. The company employs AI algorithms to design intricate winding patterns that optimize electromagnetic performance, thermal management, and mechanical integration. These AI-generated patterns are then precisely printed onto strips of flexible circuit board. This process allows for a level of detail and complexity in the winding geometry that is simply unattainable with conventional wire-winding techniques. The flexible circuit boards can then be integrated into various motor architectures, either laid flat for axial-flux designs or closed into a tubular form for radial-flux configurations.
A key advantage of this printed approach is its inherent customizability. By digitally controlling the design, Mirmex can vary critical parameters such as the conductor sizes, thicknesses, interconnections, and even the overall winding pattern itself. This flexibility enables engineers to finely tune the motor’s characteristics to optimize performance for diverse applications, specific operating environments, and stringent design constraints. For instance, a motor for a surgical tool might prioritize maximum power density and minimal heat generation in a confined space, while a drone motor might emphasize lightweight construction and high torque-to-weight ratio. The ability to precisely tailor these parameters at the design stage, followed by an automated manufacturing and validation process, significantly streamlines development cycles and enhances the efficiency of custom motor production. The automation inherent in the printing and assembly process also contributes to higher consistency, reduced manufacturing variability, and potentially lower unit costs at scale, in stark contrast to the often manual and error-prone nature of traditional winding.
Strategic Product Offerings and Versatile Applications
Mirmex Motor is strategically positioned to serve a broad spectrum of industries by offering a versatile range of products, as explained by Francisco Diaz of Mirmex Motor at MD&M West. Their offerings include bare windings for integration into existing motor designs, complete stators, and both frameless and fully assembled motors in radial or axial-flux architectures. This modular approach provides customers with flexibility, whether they require a core component for their own motor assembly or a complete, ready-to-integrate motor solution.
The advanced performance characteristics of Mirmex motors make them particularly well-suited for applications where conventional motors struggle to meet stringent demands for miniaturization, power, efficiency, and dynamic response.
