Motor ishga tushirish toki kalkulyatori
DOL, yulduz-uchburchak, yumshoq ishga tushiruvchi va ChO'Q usullari uchun motorning ishga tushirish (boshlang'ich) oqimini hisoblang. Istart = kstart × Irated.
DOL 6–8×
Yulduz-Uchburchak 2–3×
VFD 1–1.5×

Ishga tushirish usullarini taqqoslash
| Method | Joriy koeffitsient | Torque | Typical Use |
|---|---|---|---|
| DOL | 6–8 × Irated | Full | Kichik dvigatellar < 7,5 kVt |
| Star-Delta | 2–3 × Irated | ~33% | Nasoslar, ventilyatorlar, 7,5–75 kVt |
| Soft Starter | 2–4 × Irated | Variable | Konveyerlar, kompressorlar |
| VFD | 1–1.5 × Irated | Full | Istalgan turdagi, eng yaxshi nazorat |
Misol — 15 kVt dvigatel, to'g'ridan-to'g'ri ishga tushirish
Given: P = 15 kW, V = 400 V, cos φ = 0.85, η = 0.91, DOL k = 7
Irated = 15000 / (√3 × 400 × 0.85 × 0.91) = 28.0 A
Istart = 7 × 28.0 = 196.0 A
