Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.

Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
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%
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.

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.
A typical starter motor draws around 50 to 150 amps while cranking an engine. If the current draw is significantly higher or lower, it may indicate a problem with the starter motor or the electrical system.
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
To answer this question the voltage of the motor must be stated.
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
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 wiring should allow for 115 amps.
Presuming single phase and 1500 rpm. Normal running current would nearly 10 Amps but varies considerably. A real cheap one running at 3000/3600 rpm could exceed 12 amps. At 240 volt, all should be run off 15 Amp line.
To calculate the amps drawn by an 18kW motor, you can use the formula: Amps = Power (Watts) / Voltage (Volts). Assuming a standard voltage of 120V, the motor would draw approximately 150Amps. Note that actual amps will depend on the specific voltage of the motor.
1 horsepower is equal to 0.7456 kWatts, therefore 1.1184 kWatts will be the power consumption of that motor. The current draw depends on the voltage, simply use the P=UxI or I=P/U formulas to figure out the current draw (P=1118.4 Watts). some voltages: 12Vdc draw 93.2Amps 24Vdc draws 46.6Amps 110Vdc draws 10.17Amps 230Vdc draws 4.86Amps
