چکیده
بیش از 90% موتورهای الکتریکی صنایع، انواع موتورهای سه فاز القایی می‌باشد. مزیت مهم این موتورها در مقایسه با موتورهای DC و سنکرون، عدم نیاز به تعمیر و نگهداری ویژه، ارزانی، سادگی ساختمان، استحکام مناسب، و وجود گشتاور راه‌اندازی است. لذا طراحی و ساخت بهینه آنها بعنوان پرمصرف‌ترین بار الکتریکی حائز اهمیت است. استفاده از تکنیک‌های جدید هنگام ساخت به روش مهندسی معکوس در عملکرد و طول عمر الکتروموتور بسیار سودمند است. در این مقاله بهینه‌سازی و ساخت یک الکتروموتور سه فاز القایی شرکت فولاد خوزستان به روش مهندسی معکوس با تکیه بر دانش فنی و مهارت تیم اجرایی، مورد بررسی قرار گرفته است. این الکتروموتور 8 قطب،2500 کیلووات، 6600 ولت و 50 هرتز است. کلیه مراحل ساخت به روش مهندسی مجدد از برداشت مشخصات اولیه تا ساخت و تست‌های نهایی انجام شده است. پس از تایید محاسبات و صحه‌سنجی محدودیت‌ها و پارامترهای طراحی به کمک الگوریتم ژنتیک و مقایسه با پارامترهای نمونه موجود، اقدامات ساخت برای هر مرحله و اصلاحاتی جهت بهبود عایق‌بندی، تلرانس‌ها و کولینگ انجام شده است. برای بهبود عملکرد کولینگ یاتاقان‌ها، یک سیستم خنک‌کنندگی آب‌گرد که امکان تزریق آب با دما و دبی متغیر را فراهم می‌کند طراحی و اضافه شده است. نتایج نشان می‌دهد الکتروموتور تولیدی در مقایسه با نمونه اصلی دارای مقادیر بهتری در برخی پارامترها از جمله کاهش هزینه و کاهش دما بوده و لذا قابل رقابت با آن می‌باشد.

چکیده English

More than 90% of industrial electric motors are three-phase induction motors. These motors have several advantages over DC and synchronous motors, including low maintenance requirements, cost-effectiveness, simple construction, mechanical robustness, and the ability to generate starting torque. Therefore, optimizing their design and manufacturing is crucial, as they constitute the majority of electric loads in industry. The application of modern techniques, particularly reverse engineering, can significantly enhance the performance and lifespan of electric motors. This article investigates the optimization manufacturing of a three-phase induction motor for the Khuzestan Steel Company using reverse engineering, based on the knowledge and expertise of the project team. The electric motor in question is 8-pole and 2500 kW for operating at 6600 volts and 50 Hz. All stages of development—from initial specification gathering to construction and final testing—were performed using reverse engineering methods. After validating the calculations and comparing the design parameters and limitations with existing models, adjustments were made at each stage to improve insulation, dimensional tolerances, and cooling performance. To enhance the bearing cooling system, a water-circulation cooling unit was designed and integrated, allowing for adjustable temperature and flow rate. The results indicate that the newly developed motor outperforms the original sample in certain aspects, including reduced cost and operating temperature, making it a competitive alternative.
