Title: How can I calculate amps? Post by: JulieA on Sep 5, 2012 for a 5 KW machine in 220 volt?
Also for a 5 HP motor in 220 volt? Title: How can I calculate amps? Post by: LFBaller11 on Sep 5, 2012 220 / 5 I thought.
Title: How can I calculate amps? Post by: rk90 on Sep 5, 2012 Power(Watts)=Voltage(Volts)XCurrent(Amps)
To convert HP to Watts: 1hp=746W Title: How can I calculate amps? Post by: zzz1090 on Sep 5, 2012 Go here.

1 hp = 745.699872 watts, so 5 hp = 3728.499 watts. Volts times apms = watts, so 3728.499 watts / 220 volts = 16.9477 amps. Title: How can I calculate amps? Post by: lferus on Sep 5, 2012 I think that Watt= volt* Amp so 5000/220=22.72 Amp cuz 5000 is watt..
And HP is horse power HP=745.7 Watt You count that!! Title: How can I calculate amps? Post by: irina on Sep 5, 2012 Content hidden
Title: How can I calculate amps? Post by: lfiorill on Sep 5, 2012 Divide 5kW by 200 volts to give a safety factor---25 Amps.
Figure 1000 watts per HP because motors are not 100 percent efficient---so again, it's 25 amps. Now considering that you wish to start the motor, you need to allow for starting current. A factor of two is consevative, so figure 50 Amps. Title: How can I calculate amps? Post by: lfiorill on Sep 5, 2012 first one, can do. second, no can do.
P=power (W), I=AMP (A), E= VOLT. Do Know how to solve algebraic math or equations? P=I X E, --- 5000= I X 220V. Solve for I, therefore: 5000/220 = I, what's that equal to. so, I = 42.07A. (high current.) |
