Motor rpm calculation formula

Let's start from the beginning, with some basic equations: Energy = Force * distance For a mass m moving at a speed v, the energy E is: E = 0.5 * m * v * v Energy can be measured in Joules (J) or British Thermal units (BTU). 1 BTU is equal to roughly 1055 Joules. If a 2100 pound car is travelling at 60 miles/hour, the energy is about 342600 Joules or 325 BTUs.

To measure the Ke of the motor, put the motor shaft in a lathe and rotate the shaft at some speed [rpm] such as 1000rpm. With a dc motor, use a dc voltmeter to measure the armature voltage. The Ke is then the voltage you read divided by the speed in rad/sec. Convert rpm to rad/sec as- = 60sec sec 2 min min rad x rev radians x rev π [ ] Now days we have computer programs that can calculate positive displacement blower performance. They are a time saver and can quickly give you many options. Before selection programs, performance was calculated by hand to determine required performance. These equations will give the user a better understanding of how performance for a positive displacement blower is calculated.
