The 50hp motor has a current rating of 55.4 amps if its power factor is 0.8.
Another Answer:
One horsepower (electric motor) is 746 watts, so 50 horsepower is 37.3 KW. Assumed power factor is 0.8, so divide by 0.8 to get 46.6 KVA. Assumed efficiency is 0.95, so divide by 0.95 to get 49.1 KVA. The motor is three phase, so divide by three to get 16.4 KVA per winding. It is 480V so divide by 480 to get 34.1 amperes per winding. Assumed configuration is to run on delta, so multiply by 1.732 (square root of 3) to get 59.0 amperes per phase. This is very close to the 55.4 stated before.

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.
What is the volt amp of a 24volt 3.5watt motor input is 110volts?
Hooking a 24V motor to a 110V source is a certain way of destroying the motor. It'll pull as many amps through its poor circuitry as the source can deliver until either the source's fuse or the motor blows.
Can a 3 phase motor be converted into a single phase motor?
A three-phase motor will not start if one or two phases aren't connected. If while running one or two phases "drop out", it will continue to run for awhile, but will eventually burn out, unless connected to a motor saver.
What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
Why is 3 phase more efficient?
There are a few reasons. In my opinion the most common is cost. In an industrial setting, three phase power is used to power motor loads. A three phase induction motor is more efficient than a single/split phase motor. They also have higher starting torque. A three phase load will also typically have a lower amp rating for the same size load as single phase. This saves money because you can use smaller wire.
How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
How many amps per leg can you pull on a 50 amp 3 phase connector?
On a 50 amp 3 phase connector, you can pull 50 amps per leg. This means that each of the three phases can carry up to 50 amps individually, resulting in a total capacity of 50 amps per leg.

How many amps does a 1 hp electric motor pull under a load?
T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.
How many amps does 500 watt halogen pull?
At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
How many amps does a 400w power inverter pull?
Aprox 12 amps.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
How many amps does a 1.0hp pool pump pull?
One horsepower is equivalent to 746 watts. So if the motor is wired for 220 volts the current consumed is 3.39 amps. (watts divided by voltage = current) so? the label says 7.6 amps for a 1hp with a SF of 1.25 at 240 volts. 9.6 for a 1.5 hp .this is your typical pool pump motor, what motor are you getting data from ?
You found a 220volt coil on a 3 phase motor contactor and the one side of the coil is feed from B phase and the other side is also feed from B phase it would not pull in the contactor?
your not completing the circuit your only using one phase for a three phase motor
How many amps does a single phase 115 volts 1 hp 60hz pump draw?
A single-phase 115-volt 1 HP pump operating at 60 Hz will draw approximately 10 amps of current. This can vary depending on factors like efficiency, power factor, and the specific design of the pump motor.
What is the volt amp of a 24volt 3.5watt motor input is 110volts?
Hooking a 24V motor to a 110V source is a certain way of destroying the motor. It'll pull as many amps through its poor circuitry as the source can deliver until either the source's fuse or the motor blows.
