Abstract

While electric vehicles are taking their place as 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 organs 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 magnet type and magnet thickness on the design were analyzed in detail. The effects of magnet type and magnet thickness selected in the design of outer brushless direct current motor can be observed from the results, especially effecting power and torque parameters.

Bir Elektrikli Araç Prototipi İçin Gerekli Motor Gücü Hesaplanarak Tasarlanan Dış Rotorlu Fırçasız Doğru Akım Motoruna Mıknatıs Tipinin ve Kalınlığının Etkileri

Abstract

Elektrikli araçlar günümüzün ulaşım araçları olarak yerini alırken otomobil üreticileri tarafından bu konuda büyük Ar-Ge yatırımları yapılmaktadır. Bu konuda popülerleşen 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 mıknatıs tipinin ve mıknatıs kalınlığının tasarıma etkileri detaylı olarak incelenmiştir. Elde edilen sonuçlar; kullanılan mıknatıs tipinin ve kalınlığının fırçasız doğru akım motorunun tasarımında dikkat edilmesi gereken verim, güç ve tork parametrelerine etkilerini net olarak gözler önüne sermektedir.
