The speed of an asynchronous motor rotating field and thus its rotor speed depends on the number of pairs of poles in the stator field .the rotor speeds n are lower than the table values by the amount of the relevant slip speed ns. Motors are designed with up to three stators windings‚ which have different number of pairs of poles. They can therefore run at up to pairs of poles. They can be in any desired ratio to one another. A pole-changing switch is used to changing poles for the desires speed
