From efficiency to resilience: Exploring the benefits of TAU's PEEK coated wire Polyetheretherketone (PEEK) belongs to one of the most technologically advanced classes of thermoplastic polymers - polyaryletherketones (PAEK) [1]. PAEK, and especially PEEK, belong to the class of high temperature polymers. PEEK is formed using a stiff aromatic polymer base, contributing to its high temperature and wear resistance compared to other polymers. Thanks to its chemical structure, this polymer combines many advantages. Like most high performance materials, its main disadvantage is its high cost compared to other polymers such as PPS or PAI. As a result, its use is limited to areas where all the high-tech properties are required. The main characteristics of the three most popular high temperature engineering polymers, PEEK, PAI and PPS, and their comparison are shown in table [3]. It shows that PEEK has better thermal stability and can be used in higher temperature applications. The data presented previously refer to the polymer materials themselves. But after they are applied to the wire, their thermal classes of wires are as follows. Based on these values the benefits of PEEK wire are even clearer. To produce a high-quality electric motor, it is essential to use strong, stable stator winding insulation. In fact, the failure rate data for electric motors shows that stator winding damage is the second most common cause of stator failure. According to statistics [4] up to 40% of electric motor failures are due to stator failure. The most common cause of failure is defects in its winding, which consists of polymer-coated copper wire. Therefore, by ensuring reliable wire insulation, it is possible to guarantee the proper functioning of the stator - the heart of the electric car. Another special and important property of PEEK is the peculiarity of its structure. Since PEEK is a semi-crystalline polymer, it is possible to modify its properties by changing its degree of crystallinity. It can be adjusted directly during the coating process, according to technological requirements. The DryCycle® technology (patent EP3518255B1), which allows excellent control of the dynamics of the coating process, can exploit this feature of PEEK to obtain products with the desired properties. In addition, this technology avoids the use of the toxic solvents that are used in the conventional method of enamelling. This makes the process of creating magnetic wires safer and more environmentally friendly. This article presents test data from Tre Tau Engineering's DryCycle® wire made with commercially available PEEK with no fillers. About Tau Tau is a technology company at the core of energy transition, decarbonization of energy and electrification of transport. Its patented technologies reconcile the necessity of sustainable, resource-minimizing manufacturing with the power, reliability and performance that electrification requires to enable smaller, greener, longer-lasting and more powerful motors, transformers and generators.

A new frontier for high performance stators Magnetic wire is a key component in various electronic products such as transformers, inductor coils, electromagnets, electric motors and generators. The latter are particularly important to the automotive industry, and the proper functioning of an electric motor for an electric car depends on the stator. All electric motors consist of a rotating part – the rotor –, a stationary part – the stator –, bearings, and a shaft [1]. A review of several studies about electric motor failures resulted from the experience of manufacturers, repair centers and academic studies shows that the faults distribution percentage in electric motors is approximately 45% in the bearings, 35% in the stator, 10% in the rotor, and the remaining 10% in other components [2]. This implies that one-third of all motor failures are to be attributed to stator failures, the most frequent cause being the breakage of its winding. The winding, comprised of a copper conductor with polymer insulation, is highly susceptible to electrical stresses, and mechanical and thermal loads; therefore, it is the most vulnerable component of the stator. Factors such as cracks, pores, wire oxidation, insulation damage, and permeability to gases and liquids can all diminish the dielectric properties of the polymer coating. [3]. Undoubtedly, the thermal and chemical resistance of the wire is directly contingent on the selection of its insulation material. The most used insulation materials for wires include PI, PEI, PAI, and PPS. Additionally, new high-performance polymers such as PEEK and PFA have been recently introduced. Polyimides, which are applied using classic enameling technology, remain the most popular insulation material on the market due to their ability to provide a uniform coating. However, the primary issue with this technology is the use of highly toxic solvents, such as cresol, which can have adverse effects on both worker health and the environment. Consequently, finding an alternative technology for electric wire production is an urgent task. Nowadays, extrusion represents a promising alternative, as this method offers a wider range of applications. For example, it allows to apply polymers that are not suitable for the conventional enameling technology, such as PEEK, PPS, and PFA. PFA (perfluoroalkoxy) has great potential compared to other materials due to its excellent chemical resistance, which makes it suitable for use in aggressive environments. Moreover, PFA exhibits a higher resistance to partial discharges compared to common materials such as PEEK or PAI. Partial discharge is the main cause of wire insulation failure, which leads to the failure of the entire electric motor. Resistance to partial discharges is a crucial parameter to consider when designing high-voltage motors. Thus, PFA-coated wires have the potential to become a universal stator winding base for high-performance electric motors. However, the widespread use of PFA in magnet wire manufacture is limited by the difficulty of applying it to the wire due to its extremely poor adhesion to the copper surface. In order to overcome this challenge, Tre Tau Engineering developed the patented "DryCycle® technology" (patent EP 3518255B1), which allows most extrusion polymer grades to be applied to wires without the use of solvents, primers, or other copper processing. The DryCycle® process requires minimal polymer application and offers fast application times, making it both economical and environmentally friendly. This article presents the main properties of the resulting PFA wire, thus showing the wide range of possibilities and advantages of using this polymer in electric motor stators. The PFA coating was applied using the commercially available polymer Daikin AP-201. The tests were conducted in accordance with international standards IEC 60851-3, IEC 60851-5, and IEC 61934. In order to fully characterize all the properties of the wire, standard tests for magnetic wire were selected: adhesion, elongation, springback, BDV and PDIV tests. One of the non-standard test methods we used was to make hairpins and compare their electrical properties with those of the unformed samples. These characteristics were chosen to provide a comprehensive evaluation of the properties of the wire. + Adhesion: the ability of the wire to bend and stretch is a function of this factor. This is the major weakness of most fluoropolymer coatings. Tre Tau Engineering has been able to achieve strong adhesion without the need for additional primers or other fixing compounds. + Elongation: this is a measure of the tensile strength and yield strength of the wire and the resistance of the insulation to this kind of stretching. + Springback: an important parameter to create hairpins, it indicates the deflection of the wire when it is bent. + BDV and PDIV: crucial parameters to determine the electrical properties of a wire. BDV indicates the maximum discharge that the wire can withstand, PDIV indicates the inception voltage of partial discharge. Another important parameter in this study is RPDIV (initial voltage of repeated partial discharge). PDIV and RPDIV can be used to simulate the actual operation of the electric motor by predicting the possible moment of stator failure.

Tau paves the way for transport electrification at Coiltech Italia 2022, the international coil winding exhibition, held in Pordenone on September 28-29. Electric car manufacturers are racing to launch more advanced models at a rapid rate. Most importantly, industry experts are mastering innovative winding technologies for high voltage motors featuring high-power density. This helps to improve the electric vehicles’ efficiency, range and reduce recharge time. After successfully passing laboratory testing, Tau has now unveiled a new hairpin stator prototype for automotive e-traction developed in partnership with Additive Drives, a manufacturer of state-of-the-art e-motor components for mobility, automotive, industrial and racing sectors. One of the highlights of Tau winding wire is that it has all the characteristics that future mobility requires. Its partial discharge resistance and voltage resistance are 60% higher than that of competing products. In comparison to modern conductor solutions, the Tau wire delivers a higher power output and is suitable for applications above 800 volts. “We are proud to be partnering with Additive Drives to deliver our shared vision of the next level electric motor technology. At the current stage of pre-production development, we have a rare opportunity to shape decisions on product design and material sourcing based on our product performance. This milestone is of the utmost importance for Tau, now and in the future, as we want our magnet wire to play a key role in the energy transition”, said Filippo Veglia, co-founder and CSO of Tau. Tau’s magnet wire characteristics - electrical, mechanical and chemical - have been tested by FAPS and PEM Institutes in laboratory settings. Having successfully passed all tests, Tau further partnered with Additive Drives and built the first stator with Tau wire. This confirmed that Tau wire can be processed and allows for a smaller bending radius of the wire in the stator, lower friction, and a higher electrical fill factor. By rethinking traditional coating methods, Tau is leveraging the benefits that “from scratch” approach gives to put in place more sustainable practices. The DryCycle® solvent-free coating process significantly reduces any negative impact on the environment owing to the use of solid-state dry varnishes preventing VOC emissions. "We use only the materials we need and no more. Our one-layer insulation has already demonstrated very good mechanical robustness and superior dielectric strength, so we don't need to apply more polymer to obtain better results, which reduces not only the manufacturing cost but also carbon footprint. And we want to do much more than that. Our DryCycle coating is the only technology that allows 100% copper and thermoplastic polymer recycling - thus making our high-performance wire more environmentally friendly," added Veglia. The company will continue its partnership with Additive Drives to deliver an end-to-end e-motor solution that weighs less, consumes less energy and resources, and achieves the absolute maximum power density and range, Veglia said.

On September 22-23, Tau featured its high-performance magnet wire for e-mobility at Coiltech 2021 in Pordenone, preparing to build electric motors that are twice more powerful than current models. Disruptions towards sustainable manufacturing are impacting the automotive industry. The demands of e-mobility have triggered a rethink of electric motor designs and technologies. Largely unchanged for decades owing to the limits in conductor performance, electric motors have now moved into the focus of engineers who work to develop the next generation of electric motors. On top of their wish list: winding wire with unparalleled performance that has the potential to unlock massive performance for electric motors especially for transport electrification. After several years of research, Tau has unveiled the next generation magnet wire with such superior performance. Last week Tau premiered its DryCycle®️ magnet wire for e-mobility and grid applications at the Coiltech Italia 2021 fair in Pordenone. In a continued effort to move forward electric machine technology, Tau wire was designed to make motors twice as powerful, reducing its size and weight and allowing significant increases of operating voltage, frequencies and temperatures. It features partial discharge resistance that is up to 5 times higher compared to standard magnet wire and superior to wire currently used for motors in electric vehicles. “The e-car of the future will be faster, more comfortable, cheaper and with a longer range than petrol ones. To do so every electric component need to step-up. We are proposing a dramatically better magnet wire and are ready for this step”, says Filippo Veglia, co-founder and CSO of Tau. Although electric transport is a step towards sustainability, the underlying manufacturing processes have still an impact on climate and thus represent another challenge. To make it greener, Tau was guided by resource efficiency and low-carbon principles when creating its DryCycle coating process. Its strict use of solvent-free polymers eliminates the emission of harmful VOC, while a simplified production minimizes the use of resources and reduces energy consumption and waste. Tau underscored its seriousness about electrification - among the priorities of the company is the further development of grid wire for renewable energy generation. But ultimately, Veglia said, the company also wants to elevate every day of domestic life in a smaller, but not less exciting application – wire for smart home appliances. To see the very latest technologies designed for the winding industry, visit Coiltech Deutschland 2022 in Ulm on April 6-7, where Tau will be exhibiting at Booth 6-D36.

On April 06-07, Tau took part in the Coiltech Deutschland 2022 in Ulm, the fair dedicated to the supply chain of coil winding, electric motors, generators and transformers industry. For this occasion, the company showcased its unparalleled high-performance magnet wire coated with fluoropolymer to enable future electric motor architecture. Today’s battery-powered electric cars are significantly heavier than combustion vehicles and thus have high energy consumption. This represents the biggest challenge for transport electrification. OEMs and Tier1 companies strive to improve performance and efficiency of their upcoming models. The move towards 800V technology ensures faster charging and wider range. However, higher voltages stress primary insulation even more and cause partial discharge leading to the motor failure. Modern design concepts use rectangular wires in hairpin or wave windings with a thicker insulating layer. Filippo Veglia, Tau’s co-founder and CSO, speaker at the fair’s World Magnetic Conference, pointed out that with increased insulation thickness, made to withstand higher voltage, the slot fill factor has to be reduced. This lowers power density and efficiency of the motor. Since voltage and fill factor are two competing parameters, motor designers must find an optimal equilibrium which depends on the primary insulation resistance to partial discharge. “The use of special polymers like PEEK and PI, both already highly resistant to partial discharge, allows to increase the voltage without jeopardizing the fill factor of the motor. Nevertheless, fluoropolymers such as PTFE and PFA have the lowest relative permittivity among the insulating polymers and demonstrate superior partial discharge performance compared to commonly used polymers. And this advantage becomes even more evident at the usual operating temperatures of electric powertrains. A wire coated with a fluoropolymer is calculated to work with three times the voltage of the equivalent wire enameled with PAI and almost two times the equivalent wire coated with PEEK”, says Veglia. This represents a game-changing advantage for systems of 800V and more. However, fluoropolymers are rather soft materials and have relatively poor resistance to abrasion and minor clamping force. They show low adhesion and are difficult to extrude. Therefore, traditional technology of wire enameling and wire extrusion was unable to work with fluoropolymers. Tau answered these requirements with its self-developed, proprietary DryCycle technology, which guarantees operational peace of mind when coating with PFA, PTFE, ETFE and other fluoropolymers, with no solvents or primers. Based on the recent report by PEM Motion, Tau’s PFA coated wire has a much lower level of partial discharge – 75% less than PAI-coated and 30-40% less than PEEK-coated wire. Tau will again be displaying its high-performance wire for e-mobility and grid applications at Coiltech Italia 2022 in Pordenone on September 28-29, at Booth 7-A31. Save the date!

On February 22-24, Tau took part in the 9th Advanced E-Motor Technology Conference in Berlin to discuss the emerging electric motor technologies and the global trends in e-mobility industry. The market for electric vehicles continues to grow. What’s missing are the next generation technologies to advance electric driving. One of the most awaited topics of the conference covered some of the relevant strategies for future electrical motors and possible innovations through higher operating voltage in powertrains, improved resistance and power efficiency. It was said that shifting towards 800-1600 Volt motors could be the breakthrough that would finally allow electric vehicles to be charged faster and go further on one charge. Expectations are also changing in terms of the physical aspects of electric motors and their components. There is now greater importance placed on reduced weight and design optimization including insulations and use of alternative materials. “I was very happy to be a part of a network that is changing mobility and glad to ascertain the strong positioning of Tau’s customer value proposition. In the end I would like to thank IQPC for the flawless organization and the opportunity to finally meet peers in person after two years of pandemic limitations”, says Filippo Veglia, co-founder and CSO of Tau. In addition, Tau’s high-performance magnet wire for transport electrification has attracted great interest from different players including OEMs, Tier1 and Tier2 companies during the networking sessions. The dielectric performances way above any competing wire and the highest thermal class in the market make Tau’s wire the perfect fit for e-mobility. This, in fact, helps reducing the size of motors along with optimizing their efficiency. Smaller and lighter motors will allow to have additional space for batteries. Mr. Veglia said that Tau will continue the discussion on potential cooperation and supply of its magnet wire to become the de facto standard in winding industry.
