## How do you determine the amperage of a DC motor?

How to Calculate DC Motor Amperage

1. Look on the label of the DC motor. Write down the voltage and the wattage on a sheet of paper. …
2. Enter the wattage into a calculator. Press the “Divide” button and then enter the voltage you wrote down.
3. Press the “Equal” button. The result displayed is the DC motor’s amperes.

## How many amps will a motor draw?

Calculate the amps used by dividing the wattage by the voltage. For example a 500-watt motor — running on 50 volts — will draw 10 amps. A motor with the same wattage — running on 20 volts — will use 25 amps. This is the theoretical number of amps used by the motor.

## How much electricity does a 1 HP pool pump use?

Our 1 hp example pump uses 1.75 Kw per hour; whereas a 2 hp motor of the same type (UST1202) would draw 2.4 Kw per hour. That’s around 24 kWh per day, or around 720 kWh per month, just running only 10 hors per day. During the heat of the summer, many pumps need to run longer to maintain clear water.

## How much electricity does 1 hp motor consume per hour?

If I have a 1 HP motor that runs 1 hour, it will consume 750 watts, if it starts one time.
