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

GROUP 4 JULY 26‚ 2013 EE 4101 ENGR. KENNETH F. FAJILAN Reluctance Motor Introduction A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. There are various types of reluctance motor: Synchronous reluctance Synchronous reluctance motors have an equal number of stator and rotor poles. The projections on the rotor are arranged to introduce internal flux “barriers“
