How many amps does a 3 phase 25 hp motor use?

Answer 1

FLA Amps are 30 amps

Answer 2

To determine the amperage of a 3-phase motor, you would need to know the voltage at which the motor operates. Assuming a standard voltage of 480 volts for industrial applications, a 25 hp 3-phase motor would typically draw around 30-32 amps. This calculation is based on the formula: Amps = (HP x 746) / (Voltage x Efficiency x Power Factor x √3).

Answer 3

Well, darling, a 3 phase 25 hp motor typically draws around 60 amps at 240 volts. But hey, don't get too hung up on the numbers, just make sure your circuit can handle it without blowing a fuse. Happy motor running, my friend!

Answer 4

it uses 45A at 415V in Pakistan and starting current might be near 60A.

The equation you are looking for is, Amperage when horsepower is shown; HP x 746/1.73 x V x %eff x pf. As you can see that an answer can not be given without the voltage of the motor being stated. Once you have the voltage use the formula. Use .89.5 for the % eff of a standard 25 HP motor and .89 for the power factor of a standard 25 HP motor. Using the above answer's voltage, the motors amperage equals 32 amps. A motors starting current can reach 300% on start up. The starting current can reach 96 amps instantaneous until the motor amperage drops to its run amperage.
