Electric Motor Rpm Chart

A enter speed in rpm.

Electric motor rpm chart.

T ftlb p hp 5252 n 1b. Enter any 3 known values to calculate the 4th if you know any 3 values pulley sizes or rpm and need to calculate the 4th enter the 3 known values and hit calculate to find the missing value. So for example if you have a 4 pole motor on 60 hz then rpm 60 2 4 60 1800 rpm. Rpm shaft rotation speed or revolutions per minute.

T inlb torque in lb f. This simple to use calculator will give you the correct size pulley or motor speed to use if you know the actual or desired information. Enter the input voltage in volts current in amps speed in rpm and power factor. For example 2 or 4.

Poles number of poles of your motor. Motors run at a specific revolutions per minute rpm and a speed reducer is needed if you want to keep that motor but have a lower rpm. 50hz is the most common frequency outside the us. Dcac single phaseac three phase enter current in voltage.

1750 rpm 1000 rpm 3 5 inches d 2 d 2 6 125 inches. If you have any problems with the pulley calculator please email us. Choose the motor types. T inlb p hp 63025 n 1.

For example if your small pulley is 80mm diameter and spins at 1000 rpm and you need to find the second pulley size to spin it at 400 rpm enter pulley1 80 pulley 1 rpm 1000 pulley 2 rpm 400 and. At no load you have maximum speed and zero torque. Hz frequency or cycles sec. Torque in imperial units can be calculated as.

Simply enter the values and click calculate. 60hz is the most common frequency in the us. P hp horsepower delivered by the electric motor hp. For dc motor pf is one.

V enter current in amps. Electrical motor power velocity and torque equations. 1 ft lb f 1 356 nm. N revolution per minute rpm alternatively.

T ftlb torque lb f ft. For example 50 hz or 60 hz. Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge. P number of poles.

In our example input electrical power of the motor is 0 22 a x 6 v 1 32 w output mechanical power is 1000 rpm x 2 x 3 14 x 0 00126 n m 60 0 132 w. F supply frequency hz. Motor torque changes with the speed. This can be found on the nameplate of the motor.

The motor speed in rpm is calculated as n s 2 cdot 60 cdot dfrac f p. The motor speed calculator calculates the synchronous motor speed from the following parameters. Say you want to know what size pulley to use on that old planer to get 3450 rpm you know the motor rpm is 1725 and the pulley on the motor is 6.
