Electric Motor Rpm Calculator

Check the circle next to the item you are solving for and enter the remain three items in the spaces provided.

Electric motor rpm calculator.

Calculator of the rotation speed in r p m revolutions per minute of an electric motor from frequency hz and number of poles. Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge. A handy tool for checking the prm of brushless motors. At no load you have maximum speed and zero torque.

A enter speed in rpm. 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. Load adds mechanical resistance. In the calculator above fla is rla 25.

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. 1 hp 0 745 kw. Rla running load amps current drawn during normal operation of electric motor. P number of poles.

Below is a small calculator that will solve the ratio for you. The motor speed calculator calculates the synchronous motor speed from the following parameters. 1750 rpm 1000 rpm 3 5 inches d 2 d 2 6 125 inches. For example 5000 rpm.

Pulley and speed calculator. Dcac single phaseac three phase enter current in voltage. Write down the rated rpm of your motor. Enter the input voltage in volts current in amps speed in rpm and power factor.

Motor torque changes with the speed. The torque delivered from an electrical motor producing 0 75 kw 750 w at speed 2000 rpm can be calculated as t 750 w 9 549 2000 rpm 3 6 nm example torque from an electrical motor. For dc motor pf is one. V enter current in amps.

F supply frequency hz. 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. In fact many factors affect the test result such as battery discharge rating motor windings propeller loading and motor efficiency etc. Choose the motor types.

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. Below product is a great tool to measure the rpm of motors. For example 50 hz or 60 hz.
