Electric Motor Rpm Calculator

Calculating the rpm resulting from a motor and speed reducer assembly requires only basic mathematical knowledge.

Electric motor rpm calculator.

A handy tool for checking the prm of brushless motors. Enter the input voltage in volts current in amps speed in rpm and power factor. For example 5000 rpm. Below is a small calculator that will solve the ratio for you.

For dc motor pf is one. Choose the motor types. For example 50 hz or 60 hz. A enter speed in rpm.

Dcac single phaseac three phase enter current in voltage. 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. In fact many factors affect the test result such as battery discharge rating motor windings propeller loading and motor efficiency etc. 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. Rla running load amps current drawn during normal operation of electric motor. 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. In the calculator above fla is rla 25.

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. Write down the rated rpm of your motor. F supply frequency hz. Check the circle next to the item you are solving for and enter the remain three items in the spaces provided.

Load adds mechanical resistance. At no load you have maximum speed and zero torque. V enter current in amps. Pulley and speed calculator.

Below product is a great tool to measure the rpm of motors. Fla full load amps amount of current drawn when full load torque and horsepower is reached for the motor fla is usually determined in laboratory tests note. Calculator of the rotation speed in r p m revolutions per minute of an electric motor from frequency hz and number of poles. 1 hp 0 745 kw.

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. Related mobile apps from the engineering toolbox. P number of poles.
