Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
The answer is that it depends upon the a. efficiency (to determine its input power). b. supply voltage. c. nature of the supply (single-phase, three-phase, d.c., etc.)
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.
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
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.
For a 1hp 3-phase motor, the current draw will depend on the voltage supply. Typically, at 230V, a 1hp 3-phase motor will draw around 3.6 amps. However, this value may vary based on the motor efficiency and power factor.

About 3 amps, maybe slightly less.

The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
For a 1.5 hp 230v 3 phase motor, you can calculate the amperage using the formula: Amps = (HP x 746) / (Volts x Efficiency x Power Factor x √3). Assuming an efficiency of 0.85 and a power factor of 0.8, the amperage draw would be approximately 4.3 Amps.
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.
