The RPM (revolutions per minute) of a 1 horsepower (hp) motor can vary depending on the motor type and design. For example, standard induction motors typically operate at either 1,750 RPM or 3,450 RPM for 60 Hz applications, but this can differ for specialized motors or different power supplies. It's important to check the motor's specifications for the exact RPM value.
A 1 HP motor running at 120 volts will draw approximately 746 watts. This calculation is based on the formula: Watts = Volts x Amps.
Assuming the power factor is 1, a 10 hp motor operating at 600 volts in a three-phase system would draw approximately 13.33 amps.
At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
P=VI P=power V=voltage I=current therefore current drawn is 5000/400=50/4=12.5 amperes
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
To answer this question the voltage of the motor must be stated.
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
if your talking about a generator its not the hp of the engine its the size, rpm, and gearing of the generator motor
read the name plate on the motor
24.87amps 1 hp=746 watts P=IxV ... (746x8)/240
A 1 hp electric motor draws ABOUT 746 watts. Multiply volts times amps to get watts. a 1/2 hp motor will use about 3.1 amps @ 120 volts. A 12 hp motor is a VERY large motor, and will draw 8900-9000 watts of power (and use 220-440 volt power)
HP = (Current x Voltage)/746, or HP = (IE)/746 (disregarding %Efficiency) So, you have to solve for I, current: I = (746 x HP)/E
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
All motors draw less current when their load reduces.
about 80-90 hp at 5000 rpm
A 1 HP motor running at 120 volts will draw approximately 746 watts. This calculation is based on the formula: Watts = Volts x Amps.
Assuming the power factor is 1, a 10 hp motor operating at 600 volts in a three-phase system would draw approximately 13.33 amps.
