Bu makalede, elektrikli bisikletler için yüksek performanslı elektrik motoru tasarlanmıştır. Düşük hızlarda yüksek güç yoğunluğu, e-bisikletlerdeki zorlu adımlardan biridir. Elektrik motorundan istenen özellikler tartışılarak dış çap, laminasyon uzunluğu, çalışma hızı ve tork gibi gerekli parametreler belirlenmiştir. Daha sonra adım adım tasarım çalışması yürütülmüştür. Çubuk tipi gömülü mıknatıslı motorun tasarım tekniklerinden bahsedilmiş ve ilgili teknikler sonlu elemanlar analizi ile gerçekleştirilmiştir. Elektrik destekli bisiklette sınırlı bir hacimde çalışacak şekilde geliştirilmiş olan bu çubuk tipi gömülü mıknatıslı senkron motor, analiz sonuçlarından da anlaşıldığı üzere, elektrikli bisikletin ihtiyaç duyduğu tüm çalışma rejimlerinde yüksek verimli ve sessiz/konforlu şekilde çalışmaktadır.

Design of High-Power Density Spoke-Type Interior Permanent Magnet Synchronous Motor for E-Bikes

Öz

In this paper, the high-performance electric motor is designed for electrified bikes. High power density at low speeds is one of the challenging steps in e-bikes. Desired features from the electric motor are discussed and the required parameters such as outer diameter, stack length, operating speed, and torque are determined. Then step-by-step design study is executed. Spoke IPM design tips are mentioned and related analyses are performed through finite element analysis. The results show that developed spoke-type IPM in the limited volume can run the bike efficiently and silently which are the signs of successful design.
