ملخص المقالة :
پديده جريان ياتاقان‌ها در موتورهاي کنترل‌شونده توسط اينورتر، باعث نقص تدریجی ياتاقان‌ها و در نهايت توقف موتورهای الکتريکی می‌شود. در اين مقاله با تحليل ولتاژ مود مشترک که عامل ايجاد اين جريان‌ها است، الگوريتم کاهش آن در کنترل مستقيم گشتاور ارائه شده است. بر اساس تحليل ارائه‌شده، دامنه ولتاژ مود مشترک 33% کاهش می‌یابد. شبيه‌سازی‌ها در محيط سيمولينک مؤيد تحليل ارائه‌شده است. روش فوق توسط پردازنده 2812F320TMS روی محرکه پنج‌سطحی نوع خازن شناور پياده‌سازی و نتايج عملی ارائه شده است.
