Convert KW to HP Calculator
Easily convert kilowatts (kW) to horsepower (HP) using this fast and accurate online calculator. Works for both mechanical and electrical horsepower conversions...
mechanical horsepower conversion
A kW to HP Converter operates by a simple ratio of electrical to mechanical power. For example of typing into the calculator a figure in kilowatts, it multiplies it by 1.341 to determine the equivalent horsepower output.
Formula & Table Summary:
Calculate induced generator EMF using: \( E = 4.44 \, f \, N \, \Phi \). To convert three-phase EMF (star connection) to line voltage: \( V_L = \sqrt{3} \, E \). Estimate load terminal voltage under load by considering voltage drop in armature resistance and reactance: \( V_t = E - I_a(R_a + jX_s) \).
synchronous generator voltag
A Generator Voltage Calculator can figure out the generated RMS EMF due to flux, turns and frequency applying E f N . converts per-phase EMF to line voltage, works with Y/Δ connections, and may estimate loaded terminal voltage with the difference of armature drops (V t =E - I a (R a + j X s)).
