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.
To answer this question the voltage of the motor must be stated.
Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 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.
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.

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.

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%

At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
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.
