Electric motor energy consumption calculator
How can I calculate the power of an electric motor?
Instructions: Select the number of phases from the drop-down list Enter the motor rated voltage in volts (V) Enter the motor power rating and select the appropriate unit (HP or kW) Enter the power factor and efficiency of the motor Click on the "Calculate" button to see the results.
How is the RPM of an electric motor is determined?
In most cases, you can look inside the motor and count the number of poles in the winding; they are distinct bundles of wire evenly spaced around the stator core. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.

How do you calculate the energy consumption of a motor?
Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).

Motor Ratings An electric motor’s nameplate or rated power is its output power, not its electric input power. Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty.

energy cost of running a motor is usually many times greater than its initial purchase price. For example, even at the relatively low energy rate of $0.04/kWh, a typical 20-horsepower (hp) continuously running motor uses almost $6,000 worth of electricity annually, about six times its initial purchase price. 2. What is an energy-efficient motor?

Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load.
