How do I determine how many amps I need for a 3PH 10HP motor with 208 voltage?

First and foremost is the information the manufacturer puts on the nameplate of the motor. Second, the generic amperage can be found on motor charts that are on the internet. Third you can use a formula to find the approximate amperage. HP = Amps x Volts x 1.73 x pf/746. Transposed for Amperage, Amps = HP x 746/Volts x 1.73 x pf. Use pf = .9 Amps = 10 x 746/ 208 x 1.73 x .9 = 7460/323.85 = 23.03 amps. See how much easier it is to read the nameplate.

How many amps do you need to power 1hp?
The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.
How many amps drawn a 110KW motor?
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
What formula is used to find amps when hp and volts are known?
For a single-phase induction motor, allow 7 amps on a 240 v for a 1-HP motor. Therefore the formula is: current = 7 X HP x 240 / voltage
How many amps should a 0.5 horsepower motor draw?
Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.
How do you use ohm's law to determine the current flowing through a 45 ohm resistor at 1.4 amps?
The current is 1.4 amps, as already stated. The voltage is 45 x 1.4 volts.
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
How many ampere in one hp?
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
How do you get more power from 6v motor?
more voltage or amps
How many amps do you need to power 1hp?
The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.
How many amps does a 15 hp motor draw?
To answer this question the voltage of the motor must be stated.
What motor has more power one at 120 volts or one at 208 volts?
The voltage of the motor does not determine the power. However it does determine how many Fla... Or full load amp it will have when the motor is at highest speed. Usually the lower the voltage the higher the amps On the same motor. Most motors will have a name plant with this information and you should always get the amount of horsepower motor you need and make sure it will be compatible with your power source.
What is Full Load Amps?
FLA is the nameplate amperage rating of the motor when it is running at its designed horsepower and on the motors designed voltage. 746 watts = 1 HP. The FLA of a 1 HP motor at 240 volts would be W = amps x volts, Amps = Watts/Voltage. 746/240 = 3.1 amps full load. Overload the motor and the amps go higher, motor running at no load amps are lower than FLA
What is the running amps of a 45 kW motor?
To answer this question the motor's voltage must be stated and whether the supply voltage is single phase or three phase.
How many amps drawn a 110KW motor?
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
How many amps will a 120 kw dc motor require?
Depends on the voltage.
For 225 kw motor what is the amps star and delte and what is the cable size required?
Need to know what the voltage of the motor is.
How many amps does a 50 horse power electric motor use?
Need to know the voltage of the motor.
