The goal of the project is to significantly exceed the efficiency of existing electric motors while enabling cost-effective manufacturing. This is intended to reduce energy consumption, CO\u2082 emissions, and operating costs.    <\/p>\n\n<p class=\"wp-block-paragraph\">So far in the project, market and requirements analyses were first conducted, and various motor and cooling concepts were examined. Building on this, winding schemes for a solid-copper winding were developed, and the electromagnetic design of the rotor and stator was optimized with regard to copper losses and efficiency. In addition, various concepts for efficient air cooling were investigated and further developed through thermo-fluid dynamic simulations.  <\/p>\n\n<p class=\"wp-block-paragraph\">The design and conceptualization phase was completed on schedule. Subsequently, the first test segments, functional prototypes, and stators were manufactured. At the same time, a versatile test bench was developed for measuring and analyzing induction motors. Manufacturing processes\u2014including those for laminated core stacks, rotors, and hairpins\u2014were also further developed and partially automated.     <\/p>\n\n<p class=\"wp-block-paragraph\">The project is funded by the European Union and is being supported by the S\u00e4chsische Aufbaubank (SAB) as part of the funding program.<\/p>\n\n<figure class=\"wp-block-image size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"269\" src=\"https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-1024x269.jpg\" alt=\"\" class=\"wp-image-6531\" style=\"width:231px;height:auto\" srcset=\"https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-1024x269.jpg 1024w, https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-300x79.jpg 300w, https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-768x202.jpg 768w, https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-1536x404.jpg 1536w, https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Kofinanziert_von_der_EU-2048x539.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Plakat_HAPIDA.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of Plakat_HAPIDA.\"><\/object><a id=\"wp-block-file--media-c8835214-e238-42d2-8840-92aba846cca9\" href=\"https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Plakat_HAPIDA.pdf\">Poster_HAPIDA<\/a><a href=\"https:\/\/www.additive-drives.de\/wp-content\/uploads\/2026\/08\/Plakat_HAPIDA.pdf\" class=\"wp-block-file__button wp-element-button\" download=\"\" aria-describedby=\"wp-block-file--media-c8835214-e238-42d2-8840-92aba846cca9\">Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>As part of the HAPIDA research project, Additive Drives is developing a highly efficient asynchronous motor using hairpin technology for high-performance electric drives.<\/p>\n","protected":false},"author":7,"featured_media":4151,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[49,1,51],"tags":[71,78,70,72,69],"class_list":["post-6551","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-en","category-unkategorisiert","category-updates-en","tag-eu-funding","tag-hairpin-technology","tag-of-electric-motors","tag-research-and-development","tag-sab"],"_links":{"self":[{"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/posts\/6551","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/comments?post=6551"}],"version-history":[{"count":0,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/posts\/6551\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/media\/4151"}],"wp:attachment":[{"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/media?parent=6551"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/categories?post=6551"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.additive-drives.de\/en\/wp-json\/wp\/v2\/tags?post=6551"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
