To start a 15 hp motor, you typically need a transformer that can handle the motor's starting current, which can be significantly higher than its running current. Generally, the starting current can be 6 to 8 times the full-load current of the motor. For a 15 hp motor, the full-load current is about 18-20 amps at 230V or 10-12 amps at 460V, so the transformer should be rated to handle at least 100-160 amps. Additionally, it's advisable to consult the motor's specifications and consider factors like starting method and application to determine the exact transformer size.
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
What is the continuous current of 10HP star delta motor
you need the current of motor or the KW/HP rating
5 hp equals 3730 watts, and on a 3 phase 480 v system the line voltage is 277, so the current times 277 times 3 equals 3730. The answer in theory is 4.5 amps. But you have to allow for 10% power-loss in the motor, and also the power factor, which could be 0.8. Therefore the current is probably 6 to 6½ amps. Maybe 10 amps on starting up. <<>> The formula you are looking for when amperage is desired when horsepower is shown is - I = HP x 746 / 1.73 x volts x % efficiency x power factor. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. Amps = 5 x 746 = 3730/1.73 x 480 = 3730/830 x .84 x .84 = 3730/586 = 6.37 amps. Starting current will be 300% of the motors run current.

The starting current for a 20 HP three-phase motor typically ranges from 4 to 8 times the full-load current. For a 20 HP motor, the full-load current is approximately 24 to 26 amps, depending on the voltage. Therefore, the starting current can be around 96 to 208 amps. Actual values may vary based on the motor's design and specific application conditions.

YES
What is the continuous current of 10HP star delta motor
HP = (Current x Voltage)/746, or HP = (IE)/746 (disregarding %Efficiency) So, you have to solve for I, current: I = (746 x HP)/E

5-10 hp gas motor should be more than adequate. An electric motor would alos work well, especially on small lakes or sloughs without significant current.
For a single-phase induction motor, allow 7 amps on a 240 v for a 1-HP motor. Therefore the formula is: current = 7 X HP x 240 / voltage
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).
