At 20 hp, P = 20*745.7 = 14,914 watt. I = P/ (n*V*pf). If n = 0.90, pf = 0.80, we get: I = 14914/ (0.90*240*0.80) = 86.3 amp. Based on 240 volts. Claude Abraham, PhD student, EE 39 years, Will increasing the voltage, watts or amperes keep increasing the motor's rpm, as long as the motor does not break, somehow, or is there a limit to rpm growth?

Used Westinghouse 20 HP electric motor with following features: • 1755 RPM • 230/460 Volts • 49/24.5 Amps • 3 Phase • 60 Hz • 1.0 Service Factor 

5,752 products. AC motors are electrical devices that convert electrical current into mechanical rotational energy, or torque, by using alternating current (AC) from an electrical power grid or electrical generator. General purpose AC motors , also known as induction motors , are electric motors that use a rotating magnetic field to generate.

19/02/2022 · Let's see how to solve it: Rearrange the formula of hp to amps for the three-phase line-to-line system P = I * √3 * V * PF* η / 746; Apply the values (we can approximate the

AMP DRAW BASED ON HORSEPOWER What size breaker do I need for a 20 hp motor? Full Load Current: Three Phase AC Motors How do you convert HP to amps? How to Convert Horsepower to Amps Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts. Watts = Horsepower × 746. Watts = Wattsη Amps = Watts ÷ Volts. Amps = HP × 746V × η × PF.

13/12/  · For three phase motor amps calculation, the below formula is used. 3 phase motor current calculation formula is P/ (√3xVxPfxEff) or P/ (1.732xVxPfxEff) Both are the same. So our motor power is 15KW with 15 x 1000 = 15000 Watts. Motor volts are 380 volts, Eff is 0.89 and PF is 0.85 according to the above nameplate.

08/06/  · How many amps does a 3 phase 20 hp motor use? 20 *746 = 14.920 k.W i = 14.92 k.w / v * p.f * root (3) =25.9 amp 25.9 * 150% = 38.85 AMP <<>> The above question can not be calculated because the

This motor full-load amperage (FLA) calculator allows you to calculate the full-load current of the AC electric motor.
