Quvvat va tezlikdan momentni qanday hisoblash mumkin?

Torque (Nm) = 9549 × Power (kW) / Speed (RPM). This is derived from the fundamental relationship P = T × ω, where ω = 2πn/60. The constant 9549 simplifies the calculation: 60000/(2π) ≈ 9549.

kW va Nm o'rtasidagi bog'liqlik qanday?

kW dagi quvvat va Nm dagi moment aylanish tezligi orqali bog'langan: P = T × n / 9549. Istalgan tezlikda yuqori moment yuqori quvvatni anglatadi. Doimiy quvvatda moment tezlik ortishi bilan kamayadi (teskari proporsional bog'liqlik).

9549 konstantasi nima?

The constant 9549 comes from the unit conversion: 9549 ≈ 60000/(2π). It appears when converting between kW, Nm, and RPM. The exact value is 9549.2966... Using P(kW) = T(Nm) × n(RPM) / 9549.

kW ni ot kuchiga (hp) qanday aylantirish mumkin?

1 kW = 1.341 hp (mechanical horsepower). Conversely, 1 hp = 0.7457 kW. This is the mechanical (imperial) horsepower. Metric horsepower (PS) is slightly different: 1 PS = 0.7355 kW.

Moment tezlik bilan o'zgaradimi?

Berilgan quvvat manbai uchun — ha. Elektr motorlarda nominal tezlikda nominal moment mavjud. Doimiy chiqish quvvatida moment tezlikka teskari proporsional: T = 9549 × P / n. Biroq, haqiqiy motor moment egri chiziqlari turlicha bo'ladi — asenkron motorlarda ma'lum bir sirpanish tezligida maksimal moment (yuvilish momenti) kuzatiladi.

Amaliy formulalar (9549 doimiysi bilan)

Substituting and rearranging for each unknown, using the constant 9549 ≈ 60000/(2π):

O'lchov birliklarini o'zgartirish

From	To	Factor
kW	ot kuchi (mexanik)	× 1.341
hp	kW	× 0.7457
Nm	ft·lbf	× 0.7376
ft·lbf	Nm	× 1.3558
RPM	rad/s	× 2π/60

Amaliy Misol

Misol — 1500 RPM da 15 kW li elektr dvigatel

Given: P = 15 kW, n = 1500 RPM

T = 9549 × 15 / 1500 = 95.49 Nm

ω = 2π × 1500 / 60 = 157.08 rad/s

Ot kuchidagi quvvat: 15 × 1.341 = 20.12 hp

Torque in ft·lbf: 95.49 × 0.7376 = 70.44 ft·lbf

💡 9549 doimiysi: This convenient number equals 60000/(2π) ≈ 9549.2966. It eliminates the need to convert RPM to rad/s explicitly. It works when power is in kW, torque in Nm, and speed in RPM.
