چکیده مقاله :
در اين مقاله يک موتور القائی سه فاز قفس سنجابی بعنوان موتور محرک خودروی برقی (EV) به کمک روش بهينهسازی هوک-جيوز (HJ) طراحی بهينه میشود. طراحیهای بهينه با تعداد قطبهای مختلف، سرعتهای اسمی و حداکثر متفاوت، و تعداد شيارهای مختلف با هم مورد مقايسه قرار گرفته و بهترين آنها انتخاب میشوند. روش بهينهسازی مورد استفاده دارای مزايايی از جمله برنامهنويسی ساده، عدم نياز به گراديان، زمان همگرايی کوتاه و امکان تغيير تک‍تک پارامترها را دارد. تغييرات پارامترهای طراحی طرح‍های بهينه با سرعت اسمی برای موتورهای 2 و 4 قطب نمايش داده شده و مورد بحث قرار میگيرند. نتايج نشان میدهند که موتور 2 قطب با شيارهای استاتور و روتور مستطيلی، و سرعت اسمی rpm 1800 بهترين کارآيی را دارد.
In this paper a squirrel-cage three-phase induction motor, selected as the driving power of an EV, is designed optimally using Modified-Hooke-Jeeves optimization technique. The optimal designs are analyzed and compared with varying pole number, rated base speed and slot shapes. This optimization technique has same advantages such as simple programming, non-gradient, short convergence time and independently variation of each parameter. Variation of design parameters of optimally designed motors versus rated base speed for 2 and 4-pole motors are presented and discussed. The results show that a 2-pole motor with parallel-sided stator and rotor slots and rated speed 1800 rpm have the best performance
