Ikki fazali chulg‘amning aylanuvchi magnit maydoni
Ikki fazali simmetrik chulg‘amning A-X va V-U fazalari fazoda bir-biriga nisbatan qutb bo‘linmasi ning yarmiga siljigan bo‘ladi. Agar bunday chulg‘amning har bir fazasiga bir-biriga nisbatan vaqt bo‘yicha =90 burchakka siljigan (IV jIA) tok berilsa, u holda aylanuvchi magnit maydon hosil bo‘ladi.

Xulosa.
Aylanuvchi magnit maydon bayon etilgan maydonning ikki o'lchami bo'lgan nuqta orasidagi masofani ifodalovchi son. Masofa doimiy tartibda o'zgaradi, shuning uchun, bu masofa vaqt o'zgaruvchanligi mumkin. Bu xususiyatlar qo'llanilayotgan qo'llanmada quyidagi shaklda ifodalangan:
r(t) = r_0 + vt
Bu yerda:
- r(t) - vaqt t da nuqta orasidagi masofa.
- r_0 - boshlang'ich nuqta orasidagi masofa (vaqt t = 0 da).
- v - aylanish tezlanishi (o'zgaruvchan).
- t - vaqt.
Agar aylanuvchi ularning tezlanishini aniqlash uchun qo'llanilsa, odatda, quyidagi shakl ifodalangan:
\[ v(t) = \frac{{dr}}{{dt}} \]
Bu formuladan foydalanib, barcha nuqtalardagi aylanish tezlanishini aniqlash mumkin. Aylanuvchi harakati to'g'risida ma'lumot olish uchun, uchta elementning qiymatlari zarur: boshlang'ich masofa \( r_0 \), boshlang'ich tezlanish \( v_0 \) va aylanuvchi tezlanishini ifodalovchi formulalar.
