50 hp electric motor power consumption. So 37 300 watts 0 92 40 500 watts is required to be input to. Peak efficiency is at 7 5 hp. T inlb torque in lb f. Reasons to determine motor loading most electric motors are designed to run at 50 to 100 of rated load.
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. Note that most electric motors are designed to run at 50 to 100 of rated load and that maximum efficiency usually is near 75 of rated load. P hp horsepower delivered by the electric motor hp. So divide the output 50 hp by the efficiency 0 92 to get the energy required to be input into the motor to get 50 hp.
Universal motors small appliance. W is the power consumption in watts. For a 1 horsepower hp motor the load should typically be in the range 1 2 to 1 hp with maximum efficiency at 3 4 hp. Acceptable for a short period.
The equation is w av sqrt 3 where a is amperes v is volts and sqrt 3 is the square root of 33 about 1 73. A motor s efficiency tends to decrease dramatically below about 50 load. With the motor load calculator you can quickly estimate annual energy use and cost for any electric motor. What does it cost each year to operate an electric motor.
1 ft lb f 1 356 nm. Calculate the power the motor consumes while in operation. Convert watts to kilowatts by dividing the number of watts by 1 000. Electrical motor power velocity and torque equations.
Maximum efficiency is usually near 75 of rated load. With a motor with an output of 50 hp to convert the hp output into watts is. Torque in imperial units can be calculated as. A motor of this size probably typically.
Calculate three phase motor power consumption by multiplying amps by volts by the square root of three w av sqrt 3. N revolution per minute rpm alternatively. 50 hp x 746 watts hp 37 300 watts or converting to kilowatts kw 37 3 kw. The calculator is a versatile energy management tool which accepts measured current full load amps or rated horsepower inputs.
For example if the electric motor uses 50 amps at 240 volts the wattage is 50 x 240 x 1 73 or 20 760 watts.
