Optimistic Outlook: Understanding Energy Consumption of an Electric Motor

How much energy is consumed by the motor daily?

With a small air compressor operating on a 1.8 hp electric motor for 5 hours a day, how do we calculate the daily energy consumption?

Daily Energy Consumption Calculation

The 1.8 hp electric motor operating for 5 hours a day consumes 6.714 kWh of energy daily, with the conversion from horsepower to watts (1 hp = 746 W) and the multiplication by the number of hours per day.

To calculate the energy consumed by a 1.8 hp electric motor operating for 5 hours a day, we first convert horsepower to watts. Since 1 hp is equivalent to 746 W, we can find the power consumption in watts:

1.8 hp × 746 W/hp = 1342.8 W

Now, we calculate the daily energy consumption by multiplying this power by the duration of operation:

1342.8 W × 5 hours = 6714 W·h/day

To convert this to kilowatt-hours (kWh), since 1 kW is 1000 W, we have:

6714 W·h/day ÷ 1000 = 6.714 kWh/day

Therefore, the electric motor consumes 6.714 kWh of energy daily, showcasing the efficient usage of power in daily operations.
