موتورهای الکتریکی : قلب تپنده فناوری مدرن

موتورهای الکتریکی، دستگاه‌هایی هستند که انرژی الکتریکی را به انرژی مکانیکی تبدیل می‌کنند و به عبارت ساده‌تر، باعث چرخش می‌شوند. این چرخش می‌تواند برای به حرکت درآوردن هر چیزی از یک فن کوچک تا یک قطار برقی استفاده شود.

اجزای اصلی :

● استاتور: قسمت ثابت موتور که سیم پیچ ها در آن قرار دارند و میدان مغناطیسی تولید میکنند.

● روتور: قسمت متحرک موتور که در اثر برهمکنش با میدان مغناطیسی استاتور میچرخد.

چگونه موتور های الکتریکی کار میکنند ؟

وقتی جریان الکتریکی از سیم‌پیچ‌هایی که در موتور قرار دارند عبور می‌کند، یک میدان مغناطیسی ایجاد می‌شود. این میدان مغناطیسی با یک میدان مغناطیسی دیگر که در قسمت متحرک موتور (روتور) ایجاد می‌شود، برهم‌کنش می‌کند. این برهم‌کنش باعث ایجاد نیرویی می‌شود که روتور را به چرخش در می‌آورد.

انواع موتور :

موتورهای DC: با جریان مستقیم کار می‌کنند و در دستگاه‌هایی مانند اسباب‌بازی‌ها، ابزارهای برقی و خودروهای برقی کوچک استفاده می‌شوند.

موتورهای AC: با جریان متناوب کار می‌کنند و در صنایع بزرگ، لوازم خانگی و خودروهای برقی بزرگ استفاده می‌شوند.
