It could be a single phase 1/4 HP motor running on 230 volts AC.
The electrical code states that a 50 HP 460 volt three phase motor draws 65 amps. The ideal amperage would be taken from the motors nameplate as different motors of the same horsepower will have different amperage's depending on what they are designed to do.
To determine the size of the hydraulic motor needed to be equal to a 3 hp electric motor, you would need to calculate the hydraulic motor's power output in horsepower. Hydraulic motors are generally less efficient than electric motors, so you may need a larger hydraulic motor to match the power output of a 3 hp electric motor. Consult the manufacturer's specifications and consider factors such as efficiency and operating conditions.
No, you cannot use a starter rated for a 5 hp motor with a 7.5 hp motor. The starter needs to be matched to the motor's horsepower rating to ensure proper protection and operation. Using an undersized starter can lead to overheating and premature failure of the motor. It is recommended to use a starter specifically designed for a 7.5 hp motor.
3 amps on 120 volts is almost 1/2 hp. To be exact 0.48 hp, that's why I said almost 0.5 hp or 1/2 hp. So say you are thinking of buying a 3 amp grinder or table top sander and you want to know about how many HP (Horse Power) it is, the answer is 120 volts X 3 amps = 360 X 0.00134 = 0.4824 HP which is almost a 1/2 HP you can do the math from there if its a 6 amp motor then its almost a 1 HP motor or to be exact 0.4824 X 2 = 0.9648 also almost 1 HP. This is if you are on 120 volts. If you are on 110 or 125 volts its about the same.
This is the formula for horsepower. HP = I x E x 1.73 x %eff x pf./746. The efficiency of the motor will have to be guessed at along with the power factor. A motor has a lagging power factor so will use a value of .85. For the efficiency of the motor lets say 90%. The value of 746 is the amount of watts in one horsepower. Now applying the values we end up with a HP value. HP = 1.7 x 480 x 1.73 x 90 x .85/746 = 1080/746 = 1.45 horsepower.

About 3 amps, maybe slightly less.

Need to know the horsepower of the motor.
The maximum power output of a 1/3 HP fan motor is approximately 250 watts.
This is the formula for horsepower. HP = I x E x 1.73 x %eff x pf./746. The efficiency of the motor will have to be guessed at along with the power factor. A motor has a lagging power factor so will use a value of .85. For the efficiency of the motor lets say 90%. The value of 746 is the amount of watts in one horsepower. Now applying the values we end up with a HP value. HP = 1.7 x 480 x 1.73 x 90 x .85/746 = 1080/746 = 1.45 horsepower.
The torque of a 3 hp (horsepower) electrical motor operating at 1440 RPM (revolutions per minute) can be calculated using the formula: Torque (in lb-ft) = (HP × 5252) / RPM. For a 3 hp motor at 1440 RPM, the torque would be approximately 10.87 lb-ft. This value may vary slightly based on motor efficiency and design specifics.
I would go with 20 amp 3 pole 15 amp will also do
