Sagot :

The next best course of action is RPM - the speed at which it spins.

What is RPM?

RPM: revolutions per minute.

Rpm is used after a number to indicate how many times something turns one complete circle during one minute.

The engine produces 187 horsepower at 6,000 rpm.

How RPM is calculated?

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.

Then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM
