| چکیده | ||
| افزایش بازده موتورها در صرفهجویی انرژی مصرفی آن‌ها تأثیر بسزایی دارد. با محاسبه انرژی مصرفی سالانه موتور، میتوان اثر افزایش بازده در صرفهجویی انرژی را تخمین زد. یکی از روشهای کارآمد و ارزان جهت افزایش بازده انرژی موتورها، بازسیمپیچی یا طراحی مجدد سیمپیچی استاتور است. ایجاد صرفهجویی مالی و کاهش مصرف انرژی از طریق بازسیمپیچی موتورها میتواند توجه سرمایهگذاران را به خود جلب کند. در این مقاله، موتور القایی تک‌فاز با توان 75/0 اسب بخار برای عملکرد سه فاز، باز سیمپیچی شده و تحلیل الکترومغناطیسی به روش المان محدود با استفاده از نرم‌افزار فلاکس انجام شده و مشخصات عملکردی آن مورد بررسی قرار گرفته است. تحلیلهای اقتصادی شامل هزینههای عملیاتی، دوره بازگشت سرمایه و صرفهجویی سالانه انرژی نیز محاسبه شده است. طبق نتایج به‌دستآمده، بازده موتور بازسیمپیچی شده سهفاز نسبت به موتور القایی تک‌فاز، حدود %5/12 افزایش پیدا کرده و دوره بازگشت سرمایه آن با قیمت برق 13 سنت در هر کیلووات ساعت حدود یک سال به‌دست آمد. بر اساس مقایسهای که انجام شده، جایگزینی موتور القایی تک‌فاز با موتور بازسیمپیچی شده سه فاز در کلاس بازده استاندارد (IE1)، کمهزینهتر از جایگزینی با موتوری در این کلاس بازده است و صرفهجویی مالی آن در بار کامل حدود 61 دلار به‌دست میآید. جهت راستی آزمایی، نتایج آزمایشگاهی با نتایج شبیهسازی مقایسه گردید و خطای ناشی از اندازهگیری حدود %6 مشاهده شد. | ||

| چکیده [English] | ||
| Increasing the efficiency of motors has a significant effect on their energy saving consumption. By calculating the annual energy consumption of a motor, the effect of increasing the efficiency on energy savings can be estimated. One of the most effective and inexpensive ways to increase the energy efficiency of motors is rewinding or redesigning the stator winding. Cost savings and reducing energy consumption by rewinding motors can attract investors' attention. In this paper, a single-phase induction motor with 0.75 horsepower, Rewinded for three-phase operation, and electromagnetic analysis of finite element method was performed using Flux software and its operation characteristics have been analysed. Economic analysis including operating costs, payback period and annual energy savings are also calculated. According to the results, the efficiency of the three-phase rewinded motor compared with the single-phase induction motor, increased about 12.5%, and the payback period based on 13 cents per kilowatt-hour was about one years. Based on the comparison, replacing a single-phase induction moto with the three-phase rewinded motor by standard efficiency (IE1) is economical than replacing motor in this class of efficiency and cost saving in full load achieve about 61$. For validation, the experimental results were compared with the simulation results and measurement error of about 6% was observed. | ||
