Synchronous Speed in AC Machines Formulas
Synchronous speed (rps) is a significant parameter for the rotating magnetic field-type AC motor. It is determined by the frequency and the number of magnetic poles. And is denoted by N
s
. Synchronous Speed is usually measured using the Revolution per Second for Angular Velocity. Note that the value of Synchronous Speed is always positive.

FAQ
What is the Synchronous Speed?
Synchronous speed (rps) is a significant parameter for the rotating magnetic field-type AC motor. It is determined by the frequency and the number of magnetic poles. Synchronous Speed is usually measured using the Revolution per Second for Angular Velocity. Note that the value of Synchronous Speed is always positive.
Can the Synchronous Speed be negative?
No, the Synchronous Speed, measured in Angular Velocity cannot be negative.
What unit is used to measure Synchronous Speed?
Synchronous Speed is usually measured using the Revolution per Second[rev/s] for Angular Velocity. Radian per Second[rev/s], Radian per Day[rev/s], Radian per Hour[rev/s] are the few other units in which Synchronous Speed can be measured.
