An Investigation on the Cooling System of Synchronous Motor for Electric Buses

Elektrikli araclarin satisinin artmasi nedeni ile bu araclarin tam dolu batarya ile kat edebildikleri yolun uzunlugu giderek ozem kazanmaya baslamistir. Hava sicakligi veya zorlu surus durumlari elektrikli araclarin kat edebildikleri mesafeyi dogrudan etkilemektedir. Kat edebildikleri mesafeyi arttirabilmek icin elektrikli araclarin termal yonetim sistemlerinin cok iyi sekilde analiz edilmesi gerekmektedir. Bataryanin yaninda senkron motor elektrikli araclarin en onemli komponentlerinden biridir. Dolayisi ile bu calisma, sabit miknatisli bir senkron motorun literaturde de cok az ele alinan sogutma metoduna odaklanmistir. Senkron motorun sogutma metodu dogrudan bataryanin performansi ile ilgilidir. Elektrikli araclarin termal yonetim sistemini analiz edebilmek icin senkron motorun sogutma suyu sirkulasyonu metodu ele alinmis ve sayisal sonuclar deneysel sonuclar ile 0.2% hata payi ile dogrulanmistir. Motor sogutma suyunun debisinin, basinc dususune etkisi de ayrica incelenmistir.
