Elektrikli Araç Uygulamaları İçin Doğrudan Tahrikli Bir BLDC Motorunun Kapsamlı Tasarımı ve Testleri

This paper proposes a 2 kW in-wheel brushless direct current (BLDC) motor design for a light electric vehicle (EV). The EV is designed for a predefined route in electric vehicle races. The BLDC motor was directly mounted into the vehicle's wheel rim. Initially, dynamic model of EV was calculated according to vehicle characteristics. The motor's slot/pole ratio was selected as 36/32. The designs for the stator, rotor, and magnets were subsequently developed based on the motor's boundary dimensions, aiming for low cogging torque and high efficiency. To achieve this, the distance between stator tooth tips was optimized. The design was validated through 2D finite element analyses, followed by the motor's production. Performance tests conducted with the experimental setup confirmed that the design matches the experimental results.
