Ninavyokokotoa torque kutoka nguvu na kasi?

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.

Uhusiano kati ya kW na Nm ni upi?

Nguvu katika kW na torque katika Nm vina uhusiano kupitia kasi ya mzunguko: P = T × n / 9549. Kwa kasi yoyote iliyopewa, torque kubwa inamaanisha nguvu zaidi. Kwa nguvu thabiti, torque hupungua kasi inapoongezeka (uhusiano wa kinyume).

Nambari ya kudumu 9549 ni nini?

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.

Ninavyobadilisha kW kuwa hp?

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.

Je, torque hubadilika kulingana na kasi?

Kwa chanzo fulani cha nguvu, ndiyo. Injini za umeme zina torque ya kawaida kwa kasi ya kawaida. Kwa matokeo ya nguvu thabiti, torque ina uwiano wa kinyume na kasi: T = 9549 × P / n. Hata hivyo, grafu halisi za torque za injini hutofautiana — injini za induction zina torque ya kilele (breakdown torque) kwa kasi maalum ya slip.

Kikokotoo cha Torque — Power — Kasi

Badilisha kati ya torque, nguvu, na kasi ya mzunguko. Kwa kutoa yoyote mawili, hesabu ya tatu itapatikana. Inasaidia kW, Nm, RPM pamoja na mabadiliko ya vipimo vya kimataifa.

Uhusiano wa Msingi

Uhusiano kati ya nguvu, torque, na kasi ya mzunguko ni:

Where ω = 2πn/60 is the angular velocity in rad/s, and n is speed in RPM.

Fomula za Vitendo (na kigezo 9549)

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

Ubadilishaji wa Vitengo

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

Mfano wa Vitendo

Mfano — Mota ya 15 kW kwa 1500 RPM

Given: P = 15 kW, n = 1500 RPM

T = 9549 × 15 / 1500 = 95.49 Nm

ω = 2π × 1500 / 60 = 157.08 rad/s

Nguvu kwa hp: 15 × 1.341 = 20.12 hp

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

💡 Kigezo 9549: 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.
