ARMATÜR SARGISININ SARIM SAYISININ BİR ELEKTRİKLİ ARAÇ PROTOTİPİ İÇİN TASARLANAN DIŞ ROTORLU FIRÇASIZ DOĞRU AKIM MOTORUNA ETKİLERİ

Öz

Elektrikli araçlar günümüzün ulaşım araçları olarak yerini alırken otomobil üreticileri tarafından bu konuda büyük Ar-Ge yatırımları yapılmaktadır. Elektrikli araçlar için dışsal ve içsel rotorlu motorlar kullanılmaktadır. Aktarım organlarının yapıyı daha karmaşıklaştırdığı göz önünde bulundurulduğunda dışsal rotorlu motorlar küçük güç gerektiren uygulamalarda verimlilikleri ile ön plana çıkmaktadır. Bu çalışma prototip elektrikli araçlar için dış rotorlu fırçasız doğru akım motoru tasarımını içermektedir. Ayrıca yapılan analizler ile seçilen armatür sargısının sarım sayısının özellikle verimlilik, giriş gücü ve tork parametrelerine olan etkileri detaylı olarak incelenmiştir.

EFFECTS OF NUMBER OF TURNS OF ARMATURE WINDING ON OUTER ROTOR BRUSHLESS DIRECT CURRENT MOTOR DESIGNED FOR AN ELECTRIC VEHICLE PROTOTYPE

Abstract

While electric vehicles happen to be today's transportation vehicles, big R&D investments are being made by automobile manufacturers. Outer and inner rotor motors are used for electric vehicles. Considering the fact that the transmission systems make the structure more complex, outer rotor motors come into prominence in applications requiring small power. This study includes the design of outer rotor brushless direct current motor for electric vehicle prototypes. In addition, the effects of the number of turns of the armature winding selected, especially on efficiency, input power and torque parameters, were analyzed in detail.
