What Controls The Speed Of An AC Motor?
In synchronous AC motors, the rotor turns at exactly the same speed
as the rotating magnetic field; in an induction motor, the rotor
always turns at a lower speed than the field, making it an example
of what's called an asynchronous AC motor. The theoretical speed of
the rotor in an induction motor depends on the frequency of the AC
supply and the number of coils that make up the stator and, with no
load on the motor, comes close to the speed of the rotating
magnetic field.
In practice, the load on the motor (whatever it's driving) also plays a part—tending to slow the rotor down. The greater the load, the greater the "slip" between the speed of the rotating magnetic field and the actual speed of the rotor. To control the speed of an AC motor (make it go faster or slower), you have to increase or decrease the frequency of the AC supply using what's called a variable-frequency drive. So when you adjust the speed of something like a factory machine, powered by an AC induction motor, you're really controlling a circuit that's turning the frequency of the current that drives the motor either up or down.
What's The "Phase" Of An AC Motor?
We don't necessarily have to drive the rotor with four coils (two
opposing pairs), as illustrated here. It's possible to build
induction motors with all kinds of other arrangements of coils. The
more coils you have, the more smoothly the motor will run. The
number of separate electric currents energizing the coils
independently, out of step, is known as the phase of the motor, so
the design shown above is a two-phase motor (with two currents
energizing four coils that operate out of step in two pairs). In a
three-phase motor, we could have three coils arranged around the
stator in a triangle, six evenly spaced coils (three pairs), or
even 12 coils (three sets of four coils), with either one, two, or
four coils switched on and off together by three separate,
out-of-phase currents.
