This innovation also boasts a significant threefold reduction in heat waste, addressing a critical challenge in high-performance motor applications.
The company’s offerings span a comprehensive range, including bare windings, stators, as well as frameless and fully assembled motors, available in both radial and axial-flux architectures. This versatility was highlighted by Francisco Diaz of Mirmex Motor at the recent MD&M West event, a premier gathering for the medical device manufacturing industry. The inherent advantages of Mirmex’s technology position its motors as ideal candidates for a diverse array of demanding applications, including motorized surgical tools, active prostheses, advanced drones, critical aerospace designs, precision industrial equipment, and sophisticated robotics systems.
The Limitations of Conventional Motor Manufacturing
For decades, the performance of electric motors has been inextricably linked to their copper windings. The traditional process of manufacturing these windings is notoriously complex and labor-intensive. Copper wires, often fine and delicate, must be meticulously wound into precise coil geometries. This intricate task is challenging to execute consistently, leading to variations in motor performance and efficiency.
During the prototyping phase, engineers frequently resort to assembling these windings by hand, a testament to the difficulty and precision required. This manual process is time-consuming, expensive, and limits the ability to rapidly iterate on designs. Once a design is finalized for mass production, manufacturers typically invest in specialized, often prohibitively expensive, and inflexible machinery. These machines are dedicated to winding specific coil designs, meaning that any significant design alteration or the introduction of a new motor model necessitates substantial retooling or the acquisition of new equipment. This rigidity hinders innovation and increases the barrier to entry for new motor designs. Furthermore, the physical constraints of traditional wire winding limit the achievable winding density and the geometric complexity of the coils, directly impacting a motor’s power density, efficiency, and overall form factor. The inherent resistance of copper wires also generates heat, which must be managed through cooling systems, adding to the motor’s size, weight, and complexity.
Mirmex Motor’s Breakthrough: AI-Driven Printed Stator Technology
In stark contrast to these conventional methods, Mirmex Motor employs an innovative, AI-driven approach to create its winding patterns. This revolutionary process begins with sophisticated artificial intelligence algorithms that design intricate and optimized winding geometries. These patterns, impossible to achieve through traditional wire-winding techniques, are then precisely printed onto strips of flexible circuit board.
The manufacturing process is remarkably adaptable. For axial flux architectures, these printed strips are laid flat, maximizing surface area for magnetic interaction. For radial flux architectures, the strips are expertly closed into tubular forms. A cornerstone of Mirmex’s innovation is the high degree of automation in both the manufacturing and validation phases. This not only ensures unparalleled precision and consistency but also significantly reduces production costs and lead times compared to manual or semi-automated winding processes.
The flexibility of this printed circuit technology allows for an unprecedented level of customization and optimization. By varying critical parameters such as the conductor sizes, thicknesses, interconnections, and even the fundamental pattern itself, the winding can be meticulously tailored. This optimization capability allows Mirmex motors to be precisely engineered for a vast range of different applications, diverse operating environments, and specific performance constraints. This level of design freedom stands in stark contrast to the rigid limitations of traditional winding, where design choices are often dictated by manufacturing feasibility rather than optimal performance. The result is a motor that not only competes effectively with other synchronous and slotless brushless direct current (SBLDC) motors but often surpasses them in key performance metrics due to its superior winding architecture.
Unpacking the Performance Advantages
The technological leap represented by Mirmex’s printed-stator motors translates into several significant performance advantages that are critical for modern high-tech applications.
Compactness and Miniaturization: The claim of being 50% more compact than comparable slotless motors is a game-changer. This reduction in size is primarily achieved through the ability of printed circuits to create extremely dense and precise winding patterns that maximize the utilization of available space. Traditional wire windings, even in slotless designs, inherently have gaps and limitations in how tightly wires can be packed. Printed circuits, conversely, allow for continuous, highly integrated conductor paths that eliminate wasted space. This compactness is crucial for industries where miniaturization is paramount, such as in medical implants, micro-robotics, and portable electronics, enabling smaller, lighter, and more aesthetically pleasing devices without compromising power.
Enhanced Dynamics and Responsiveness: The 70% increase in dynamism refers to the motor’s ability to respond quickly and precisely to changes in load or command. This superior dynamic performance stems from several factors inherent in the printed winding design. The precise and uniform nature of the printed conductors minimizes electrical losses and parasitic effects, leading to a more direct and efficient conversion of electrical energy into mechanical motion. Furthermore, the lower inertia often associated with these designs allows for faster acceleration and deceleration. In applications like robotic arms or surgical instruments, this translates to smoother, more accurate movements, enabling complex tasks with higher precision and speed. For drones, it means quicker maneuvers and better control in challenging flight conditions.
Superior Thermal Management: One of the most compelling advantages is the threefold reduction in heat waste. Heat generation is a major limiting factor in motor performance and longevity. Excessive heat can degrade insulation, demagnetize magnets, and reduce overall efficiency. Mirmex’s printed windings likely achieve this dramatic reduction through a combination of factors. The optimized conductor paths minimize electrical resistance, thereby reducing I²R losses (heat generated by current flowing through resistance). Additionally, the planar or tubular nature of the printed windings may allow for more efficient heat dissipation pathways compared to tightly packed traditional wire coils, which can trap heat. Less heat waste directly translates to higher continuous power output for a given motor size, extended operational lifespan for the motor and surrounding components, and a reduced need for bulky, heavy, or complex active cooling systems. This is particularly vital in sealed environments or applications where space and weight are at a premium, such as implantable medical devices or aerospace components.
Manufacturing Efficiency and Flexibility: Beyond performance, the automated manufacturing and validation processes offer significant operational benefits. The ability to vary conductor sizes, thicknesses, interconnections, and patterns through AI-driven design and printing allows for unparalleled customization without the need for extensive retooling. This flexibility enables rapid prototyping, quicker iterations, and efficient production scaling for diverse motor specifications, ultimately leading to faster time-to-market and reduced manufacturing costs.
