Higher revolutions per minute equate to more fuel burnt in the same amount of time and more power produced. Because of this, most consider higher RPMs racing RPMs. Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower.

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 for the number of seconds in a minute by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

x revolutions / min. Because of this math, lb-ft of torque and horsepower will always be the same at 5,252 RPM.

CARS.COM RPM stands for revolutions per minute, and it's used as a measure of how fast any machine is operating at a given time. In cars, rpm measures how many times the engine's crankshaft makes one full rotation every minute, and along with it, how many times each piston goes up and down in its cylinder.

Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM) Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM) Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

The marking "SPL" is a trick some manufacturer's like A.O. Smith use on their homeowner-grade air compressor motors. They'll advertise these as 5 horse air compressors, but that's "peak horsepower". The real horsepower is less than 5, so they put "SPL" in the horsepower spot on the dataplate for "SPeciaL".

A magnetic field is created in the stator poles that induces resulting magnetic fields in the rotor which follow the frequency of the changing magnetic field in the stator. Two pole AC motors operating at 60 Hz will always run at approximately 3600 rpm, and four pole AC motors will have speeds around 1800 rpm.

Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM) Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM) Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
