Question 1

Tokdan dvigatel burilish momentini qanday hisoblash mumkin?

Accepted Answer

Step 1: P = √3 × V × I × cos φ × η (shaft power in W). Step 2: T = P × 9549 / n (in N·m), where n is speed in RPM. The constant 9549 converts kW and RPM to N·m.

Question 2

9549 konstantasi nima?

Accepted Answer

T = P × 9549 / n comes from T = P / ω, where ω = 2πn/60. So T = P × 60/(2π×n) = P × 9549/n when P is in kW and T in N·m. For P in watts: T = P × 9.549/n.

Question 3

Nominal moment va ishga tushirish momenti o'rtasidagi farq nima?

Accepted Answer

Nominal moment — to'liq yuklamada va nominal aylanish tezligida uzluksiz ishlash momenti. Ishga tushirish momenti — nol tezlikdagi (rotor qulflangan holat) moment. Standart asinxron dvigatellar uchun ishga tushirish momenti odatda nominal momentning 150–300% ini tashkil etadi.

Question 4

Tezlik momentga qanday ta'sir qiladi?

Accepted Answer

Doimiy quvvat sharoitida: T = P/ω, ya'ni moment tezlikka teskari proporsional. VFD bilan bazis tezlikdan pastda (doimiy V/f): moment taxminan doimiy qoladi. Bazis tezlikdan yuqorida (maydon zaiflashtirish rejimi): moment 1/n nisbatida kamayadi.

Question 5

Val momenti va havo teshigi momenti o'rtasidagi farq nima?

Accepted Answer

Havo teshigi momenti — dvigatelda hosil bo'ladigan elektromagnit moment. Val momenti ishqalanish va havo qarshiligi yo'qotishlari tufayli undan past bo'ladi. Amaliy maqsadlar uchun: T_val = P_chiqish × 9549 / n.
