How many amps does a 240 volt 5HP motor use?
Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V × .9. Amps = 746 120 V × .9.

Method 3 Method 3 of 3: Calculating Amperage with Ohm's Law Download Article
- Familiarize yourself with the concept of Ohm's Law. Ohm's Law is an electrical principle that establishes a relationship between the voltage and current of a conductor.
- Determine the voltage of your circuit. If your circuit runs on a 9-volt battery, you already have part of the equation.
- Find the resistors in your circuit. ...
- Apply Ohm's Law. ...
How much power does a 5 HP electric motor use?
1 HP = 745.7W, so on a rough calc 5HP = 3728W.

How many watts is a 5 HP motor?
A true 5 hp on 220 volts would require 28 amps to run on 220 or 6160 watts so at a minimum I would think 20,000 watt generator.
Can 5 HP motor run on inverter?
No, a single-phase motor cannot be used. Doing so will cause a failure. The Inverter creates a virtual alternating current with high-speed switching.
