This design win represents the successful implementation of the NKN slot-liner solution, thanks to the high thermal conductivity of the Kapton<sup>\u00ae<\/sup>&nbsp;MT+ polyimide film and electrical insulation from Nomex<sup>\u00ae&nbsp;<\/sup>paper.<\/p>\n\n\n\n<p>DuPont collaborated with an e-motor developer and a leading electrical insulation system provider to develop a slot-liner solution. Slot liners protect the copper wires in the e-motor from the outer steel wall, dissipating heat to the outside and enabling the motor to operate efficiently at a cooler temperature. In addition, the NKN laminate sandwiches Kapton<sup>\u00ae<\/sup>&nbsp;MT+ film between two layers of DuPont<sup>\u2122<\/sup>&nbsp;Nomex<sup>\u00ae&nbsp;<\/sup>&nbsp;paper for electrical insulation, making it ideally suited for this application.<\/p>\n\n\n\n<p>&#8220;With global demand for EVs continuing to accelerate, e-motors must run as safely as possible with the highest energy efficiency,&#8221; said&nbsp;Greg Randisi, Automotive Global Marketing &amp; Business Development Leader with DuPont Interconnect Solutions. &#8220;This collaborative solution signals a significant win for our Kapton<sup>\u00ae<\/sup>&nbsp;MT+ based high thermal conductivity NKN slot liners that we plan to make available to other EV OEMs as companies build out their more advanced e-motor offerings.&#8221;<\/p>\n\n\n\n<p>Failure in the field is not an option. Just as designers of high-speed traction motors and other high-performing motors have trusted in DuPont solutions for decades, EV design engineers can rely on the Kapton<sup>\u00ae<\/sup>&nbsp;MT+ based NKN slot liner solution to prevent failures in critical eMotor systems. The DuPont\u2122 Kapton<sup>\u00ae<\/sup>&nbsp;MT+ based slot liners can be proliferated to other EV OEMs as part of motor providers&#8217; e-motor\/powertrain offerings, as their high thermal performance enables OEMs to make more compact, better-performing e-motors with superior heat dissipation. Additionally, Kapton<sup>\u00ae&nbsp;<\/sup>MT+ provides superior voltage endurance, enabling longer life of e-motors at high voltages, 800V+. DuPont offers a variety of thicknesses of Kapton<sup>\u00ae<\/sup>&nbsp;MT+ film that can effectively dissipate heat in larger e-motors such as those used in trucks and novel aircraft.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DuPont Interconnect Solutions, part of the&nbsp;Electronics &amp; Industrial&nbsp;business segment announced that a leading provider&hellip;<\/p>\n","protected":false},"author":1,"featured_media":2018,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[190,43],"tags":[184,192,189],"class_list":["post-2009","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ev-charging","category-global-news","tag-ev-news","tag-ev-news-online","tag-ev-reporter"],"_links":{"self":[{"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/posts\/2009","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/comments?post=2009"}],"version-history":[{"count":1,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/posts\/2009\/revisions"}],"predecessor-version":[{"id":2019,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/posts\/2009\/revisions\/2019"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/media\/2018"}],"wp:attachment":[{"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/media?parent=2009"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/categories?post=2009"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/evconnectmag.in\/index.php\/wp-json\/wp\/v2\/tags?post=2009"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
