    Numer_referencyjny_programu_pomocowego: SA.42799(2015/X), pomoc_de_minimis: §42 rozporządzenia Ministra Infrastruktury i Rozwoju z dnia 10 lipca 2015 r. w sprawie udzielania przez Polską Agencję Rozwoju Przedsiębiorczości pomocy finansowej w ramach Programu Operacyjnego Inteligentny Rozwój 2014–2020.Komutator maszyny prądu stałego jest bardzo wrażliwym elementem, szczególnie w przypadku poddania go ciągłym obciążeniom prądami znamionowymi. Współpraca komutatora z grafitowymi szczotkami przy pełnym obciążeniu maszyny niesie ze sobą niebezpieczeństwo przegrzania poszczególnych działek komutatora. Efektem tego może być poluzowanie łączenia działki komutatora z przylutowanym uzwojeniem wirnika, a także wysunięcie czoła działki poza obrys pozostałych działek komutatora, co skutkuje szybszym zużywaniem szczotek i dodatkowym nagrzewaniem. Ww. efekty doprowadzają z czasem do awarii maszyny, konieczne jest zatem sprawdzanie stanu komutatora. Projektowane urządzenie powinno umożliwiać ocenę temperatury poszczególnych działek komutatora maszyny prądu stałego, bez konieczności zatrzymywania maszyny. Dodatkowo przewidziane jest monitorowanie wymiarów geometrycznych komutatora w taki sposób, aby możliwe było wyróżnienie działek, które wskutek rozszerzalności termicznej wysunęły się w stosunku do średniej średnicy komutatora. Pozytywne rezultaty uzyskane w przypadku maszyn komutatorowych dałyby możliwość zastosowania tej metody także do pomiaru temperatury pierścieni wirników maszyn synchronicznych i asynchronicznych. Opracowany prototyp, po pozytywnych testach w warunkach eksploatacji przemysłowej umożliwi spóce świadczenie nowej, innowacyjnej usługi. Usługa ta może być wykonywana dla różnych gałęzi przemysłu (np. energetyka, hutnictwo, ciepłownictwo, górnictwo), w instalacjach przemysłowych, w których stosuje się silniki dużej mocy. Korzyści z zastosowania tego rozwiązania byłyby oczywiste – obniżenie kosztów eksploatacji maszyn związanych z ich przestojami w celu testowania sp (Polish)
