Dişlisiz Asansör Sistemleri İçin Alüminyum Sargılı Sabit Mıknatıslı Senkron Motor Tasarımı ve Maliyet Analizi

Abstract

Günümüzde, artan enerji talebinin karşılanması için yüksek enerji tüketimine sahip verimsiz sistemlerin yerine daha az enerji tüketen sistemlerin geliştirilmesi üzerine çalışmalar büyük önem arz etmektedir. Gün geçtikçe kullanımı yaygınlaşan asansör sistemlerinde, enerji tüketiminin düşürülerek daha verimli hale getirilmesi için dişli aktarma yapıları yerine yüksek moment yoğunluğuna sahip sabit mıknatıslı senkron motorlar ile doğrudan sürüş tercih edilmektedir. Ancak, sabit mıknatıs ve geri besleme elemanı kullanılması bu motorların maliyetini yükseltmektedir.  Bu çalışmada, bakır sargı yerine alüminyum sargı kullanılarak sabit mıknatıslı senkron motor maliyetinin azaltılması hedeflenmektedir. Aynı çıkış parametrelerini sağlayacak şekilde hem bakır sargılı hem de alüminyum sargılı sabit mıknatıslı senkron motor modelleri Maxwell programı ile oluşturularak analiz edilmiştir. Analiz sonucunda elde edilen veriler ışığında her iki model, maliyet, hacim, ağırlık ve verim açısından detaylı olarak karşılaştırılmaktadır. Elde edilen maliyet kazancı asansör motoru üreticilerinin rekabet gücünü arttırmak için önerilmektedir.

Design and Cost Analysis of Permanent Magnet Synchronous Motor with Aluminum Winding for Gearless Elevator Systems

Abstract

Nowadays, it is of great importance to research on the development of less energy-consuming systems instead of inefficient systems with high energy consumption in order to meet the rising energy demand. In elevator systems becoming widespread day by day, direct drive is preferred with permanent magnet synchronous motors capable with high moment density instead of gear transmission in order to reduce energy consumption and make it more efficient. However, the use of permanent magnets and feedback devices increases the cost of these motors. In this study, it is aimed to reduce the cost of permanent magnet synchronous motor by using aluminum windings instead of copper windings. Both the copper-wound and aluminum-wound permanent magnet synchronous motor models have been designed with the same output parameters and analyzed with the RMxprt-Maxwell program. According to analysis results, both models have been compared in terms of cost, volume, weight and efficiency. The resulting cost reduction is proposed to increase the competitiveness of elevator motor manufacturers.
