Electric motor horsepower To calculate the horsepower of an electric motor, use this formula: volts ? amps ? rated efficiency ? 746 watts. Let’s take, as an example, an electric motor rated at 480 volts, 50 amps that has a 92% rated efficiency.
How much HP does an electric motor have?
Electric Motors
An electric motor’s output is measured in kilowatts. Companies that build electric cars continue to talk about horsepower because consumers are still more familiar with that type of unit. The equation is as simple as hp = kW x 1.369, so a 100-kW motor produces 136 horsepower.
How powerful is a 1hp motor?
1 HP = 746 Watts. If you put P= 746 Watts in above formula, you will get rated or full load current of the motor, actual current may vary from this depending on the loading of the motor.

How much power does a 2 hp motor use?
If a 2 horse power motor is doing 2 horsepower of work then in the load about 1500 Watts of energy is used in the load.
How much does it cost to run an electric motor?
Expect actual operating costs to vary. For example, a 460-volt, three-phase, standard efficiency 100 HP motor operating under full load for 8,760 hours per year will probably cost just over $48,000 per year to operate at an electric rate of $0.10 per kWh.
How much power does a 50 hp electric motor use?
37,300 Watts
To get 50 HP, you need to divide the output by the efficiency to get the energy required to be input into the motor. In order to get the 50 HP output, 37,300 Watts must be input to the motor.
How do you calculate the horsepower of an electric motor?
Use this formula to estimate motor horsepower: Horsepower (hp) = Voltage x Amerage x % EFF x power factor x 1.73/746.

How much Power does a 3 HP motor use?
3 hp is 2.2 KW. Considering 400 Volts at the terminal for 415V Motor and 85% Efficiency, it will draw 2200*0.85 i.e. Input KW =2.58 KW. Hence, the Power Consumption will be 2.58 KW at Full Load.
How much current does a 1 HP motor draw?
AMP DRAW BASED ON HORSEPOWER
| HP | 1 Phase Amps | |
|---|---|---|
| 115 volt | 230 volt | |
| 1/2 | 9.8 | 4.9 |
| 3/4 | 13.8 | 6.9 |
| 1 | 16 | 8 |
How many units does a 1 HP motor consume?
17.904 units
There is a 1 HP motor here. 17904 Watt-hour is equal to 17904/1000 units and 1 HP for 24 hours is 746 24. When the 1 HP motor is running continuously for 24 hours, 17.904 units of Power will be consumed.
How many watts does a 25 hp motor use?
25 hp = 18,642.5 Watts according to my calculator.
How much Power does a 7.5 hp motor consume?
Let us assume that motor is operating at full load so it will consume 7.5 hp or 5.59 or 5.6 kW approx. Let us assume motor has efficiency of 90 %, motor at full load gives around 90 % efficiency, so the power input to motor is 5.6/0.9=6.22 kW. Energy consumption in 2 hrs = 6.22×2=12.44 KWh or 12.44 unit.
How much power does a 20 hp motor use?
If the motor actually delivers 20 horsepower (hp) of mechanical power, then the motor will draw 49 amps.
