How many amps does a 10 hp motor use?

AMP DRAW BASED ON HORSEPOWER

HP 1 Phase Amps 3 Phase Amps
115 volt 208 volt
5 56 16.7
7-1/2 80 24.2
10 100 30.8

How do you calculate no load amps of a motor?

In-L = FLC * R/100

  1. Where In-L is the No Load Current (amps)
  2. FLC is the full load current (amps)
  3. R is the percentage of full load current (%) star motor = 10% delta motor = 30% dc motor = 25%

How many HP is 20 amps?

Common Amps to Horsepower Conversions

Amps Horsepower Efficiency
15 A 2.17 HP 90%
20 A 2.9 HP 90%
25 A 3.62 HP 90%
30 A 4.34 HP 90%

How do you calculate no-load?

The calculation of no-load (Iron) losses is based on the ratio of the voltages being measured and the rated voltage squared and the results multiplied by the no-load value from the data sheet.

Does an electric motor draw more amps under load?

This is because when running, it is also acting as a generator, creating an EMF which opposes the applied EMF and reduces the overall current. As more mechanical load is applied, the motor slows, the back emf decreases, and more current is drawn.

How do you calculate the starting amps on a motor?

You can multiply the code (amps) times the Horsepower of motor to determine starting amps. Find a list of codes and the amps here. Cycles (Hz) – All U.S. electrical appliances run at 60 cycles per second.

How many amps does a 7.5 hp motor draw?
