Bir ˙Insansız Kara Aracı ˙Için Yüksek Verimli Fırçasız Do˘gru Akım Motoru Tasarımı

Insansız kara araçları (˙IKA) sahip oldukları farklı modüller sebebiyle ara¸stırmacılara çe¸sitli çalı¸sma alanları sunmaktadır. Bu modüller sensör teknolojileri, gömülü sistemler, haritalandırma ve konumlama, yörünge takibi, mekanik tasarım, elektrik motoru ve batarya teknolojileri gibi alanlardan olu¸sabilmektedir. Bu ara¸stırma alanlarından elektrik motoru teknolojisinde her ne kadar bahsedilen di˘ger alanlara göre daha fazla limit tasarım de˘gerlerine ula¸sılmı¸s olsa da insansız araçların sahip oldukları karma¸sık ve kendine özgü kısıtlar sebebiyle farklı tasarım yakla¸sımlarına ihtiyaç duyulmaktadır. Yapılan çalı¸smada çok yönlü hareket kabiliyetli, dü¸sük sürtünmeli ve yüksek titre¸simli bir ˙IKA için özel bir dı¸s rotorlu fırçasız do˘gru akım motoru (FDAM) tasarlanmı¸stır. Yapılan tasarımda dü¸sük hız, yüksek moment ve yüksek verimde bir FDAM’u kısıtlı alan ve hacim ko¸sulları göz önünde bulundurularak kolay imal edilebilir bir yapıda geli¸stirilmi¸stir. Çalı¸smada analitik çözümler ANSYS RMxprt, 2 ve 3 boyutlu analizler ise sonlu elemanlar yöntemine (SEY) dayanan ANSYS Maxwell ile yapılmı¸stır. Elde edilen sonuçlar, ba¸slangıç motivasyonu ile tasarım çıktıları arasındaki uygunlu˘gu göstermi¸s ve üretilebilir bir elektrik motoru geli¸stirilmi¸stir.

High Efficiency Brushless Direct Current Motor Design for an Unmanned Ground Vehicle

Unmanned ground vehicles (UGV) offer different study areas to researchers due to their various modules. These modules can be included sensor technologies, embedded systems, mapping and localization, trajectory tracking, mechanical design, electric motor and battery technologies. Although electric motor technology from these research areas has reached more limit design values than the other areas mentioned, different design approaches are needed due to the complex and specific constraints of unmanned vehicles. In this study, a special outer rotor brushless direct current motor (BLDC) has been designed for UGV which has multi-axis movement, low friction and high vibration. Low speed, high torque and high efficiency in the design of a BLDC is restricted to space and volume can be easily manufactured. In the study, analytical solutions by ANSYS RMxprt, 2 and 3 dimensional analyzes are performed based on finite element method (FEA) using ANSYS Maxwell. The results obtained show the validity between the initial motivation and the design outputs and an electric motor which is producible, has been developed.
