ASENKRON MOTORUN BOYUNDURUK VE DİŞ BOYUTLARININ MOTOR PERFORMANSINA ETKİLERİ

Abstract

Bu çalışmada sincap kafesli bir asenkron motorun stator ve rotor boyunduruk ve diş boyutlarının motor performansına etkileri sonlu elemanlar yöntemi kullanılarak belirlenmiştir. Referans motorun stator iç çapı artırılarak (dış çap sabit) oluşturulan yeni motor modelinden elde edilen performans değerleri, referans motordan elde edilen değerler ile karşılaştırılmıştır. Ayrıca yeni oluşturulan motor modeli ile referans motor modelinden elde edilen manyetik alan dağılımları, nominal çalışma noktasındaki işletme değerleri, elde edilen kayıp güç değerleri, nüve ağırlıkları ve performans grafikleri (moment, verim) karşılaştırmalı olarak çizelge ve grafikler halinde verilmiştir.

THE EFFECTS OF YOKE AND TOOT DIMENSIONS ON INDUCTION MOTOR PERFORMANCE

Abstract

In this study, the effects of stator and rotor yokes and dimensions of stator and rotor teeth on motor performance in squirrel-cage induction motor were investigated using finite element method. A new motor model was obtained by means of increasing the inner stator diameter of the reference motor (taken outer diameter fixed). The performance values obtained from new motor model were compared with those obtained from reference motor model. In additionally, the magnetic field distributions, operational characteristics for nominal point, power loss values, core weights and performance graphics (such as, torque and efficiency vs. slip) were given.
