A 3hp motor refers to an electric motor with a power output of three horsepower (hp). Horsepower is a unit of measurement that quantifies the power a motor can produce, with one horsepower roughly equivalent to 746 watts. Therefore, a 3hp motor can deliver about 2,238 watts of power, making it suitable for various applications requiring significant energy, such as pumps, compressors, and industrial machinery.
What else can I help you with?
How much current will a 5 hp 1 phase 120V motor pull?
The largest 120V motor generally available is 3hp. A 3hp, 120V motor draws about 30 amperes. All true 5hp motors I have seen are 230V or higher. Note that some motors, such as compressors and vacuum cleaners, use artificially high hp numbers to entice you to buy their unit (they will use terms like peak-developed hp, etc.). These ratings are not true hp, and you just have to go by the nameplate rating on the unit. For instance, I have a Sanborn Air Compressor that claims 4 PEAK horsepower, yet only draws 17 amperes at 120V. Its really closer to a 2hp motor.
What is the full load running current of a 3hp 208volt single phase continuous duty ac motor?
It would probably be 20-30 amps. <<>> The electrical code book states a value of 18.7amps for a 3HP 208 volt motor. If the nameplate data is available it is always best to use it when calculating wire size and overload protection for the motor.
How do you find the no load amp rating of a motor?
Full load amps is found on the motor's nameplate, and is unique to that particular brand and model number. A Magnetec 2hp motor will draw different amps than a Baldor 2hp, etc. There are high efficiency motors, and not so high as well. Consult the nameplate. If you want a "rule of thumb" to estimate the RLA (Running Load Amps - this is the term most often found on the nameplate - same as full load amps), then use this: Figure about 1400 watts per horsepower. Divide Watts by volts to get Amps, for example: * 3hp motor, 120V * 3hp X 1400 W = 4200 W * 4200 W / 120 V = 35 A This formula is only for single-phase motors! I looked up a typical 3hp 120 V Baldor motor in the Grainger's catalog, and the RLA for it was 32.0, so this will get you in the ballpark. I have seen 3hp 120 V motors as low as 25 A and as high as 40, so DO NOT use the rule of thumb to size branch circuit conductors or overcurrent protection! For 3-phase motors: Figure about 1100 watts per horsepower (3-phase is a little more efficient). Divide Watts by Volts, then divide the answer by 1.73 to get Amps, for example: * 3hp motor, 208V 3Ph * 3hp X 1100 W = 3300 W * 3300 W / 208 V = 15.86 * 15.86 / 1.73 = 9.16 A This formula is only for 3-phase motors! My Grainger's catalog motor with the same Voltage and HP had a nameplate rating of 8.34 A.
How many amps does a half horse power motor draw at 220 Volts?
to calculate: 1hp=745W 3hp=745*3=2.2Kw assuming a 3 phase motor power is V*I*pf*the square root of 3 I would gues a PF of 0.8 if its a resonable motor which gives about 7.2 amps per phase. if the PF is bad say .65 it could pull up to 9 amps in short, too little information to give you the actual answer.
An electric motor is a generator in reverse meaning that it can turn electricity into?
An electrical motor generator in reverse means that it can turn the electrical energy to mechanical and kinetic energy.

How much compression should a 3hp Briggs have to run properly?
My daughters mini bike with a 3hp Briggs has 80psi compression and runs great. A motor I got "running" off eBay has 55psi compression, runs but has NO power. -Jason
Why does my 3hp Briggs and stratton motor clutch slip how do you stop it?
not sure. i want to know too. What is this on? need more info.
What is the correct spark plug for 1968 3hp 2cyl Johnson outboard motor?
David Underhay The decal on my 1968 3hp Johnson says use either of: Champion J4J, AC M42K, Autolite A21X sparkplugs. You may have to find the current equivalents
The gas to oil ratio for a 1965 Johnson 3hp?
My twin cylinder 1965 Johnson 3hp uses a 50:1 gas:oil ratio.
Do 1 phase electric motors need starters?
it depends on the load and size of the motor if the motor has to drive heavy loads from initial state it require more torque, for this we use star-delta starters where load on motor in permissible then we use a DOL starters DOL starters are direct supply feeders to the motor so there is no rule to use a starter. we can use anything to swith the motor. for protection we need a overload relay and you ask for a 1ph motor, i.e maximum 3hp motors are available for less than 2 hp motor you can use a 6amp switch used in household or a 6amp mcb (includes overload). for 3hp a 16 amp switch or a 10amp mcb is more than enough

How many watts dose a 3hp compressor need?
A 3 horsepower (hp) compressor typically requires around 2237 watts to operate. This can vary slightly depending on the efficiency of the compressor motor.
