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.)
No load amps for 75 hp mitor
22 kw motor how much takes ampares with load
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.
There are many types of overload protection these days and all are based on the FLA (full load amps) of the motor.
Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.
a 3 phase 415 volts 50 HZ 15 HP motor draws: 1. On no load 3.6 amp after a starting kick of around 18AMP 2. On a full load : a starting kick of 108 amp for few seconds and then18.3 amp. 3. On rated load(this means the motor is selected such that the load is 80% of the motor capacity) 14.64 amp with a starting kick of 88Amp.
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.

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 pool pump motor which is drawing half the amps listed on its nameplate can indicate a problem with the windings or a lack of incoming current. Pumps will only draw as many amps as are required to operate under the current load.

481 amps if the load has a power factor of 1, but if the power factor is less than one (e.g. if it's a motor) you also have to divide by the power factor.
There are zero amps in 3000 volts. A load needs to be connected to the voltage.
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
