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

Introduction An automobile or motor car is a wheeled motor vehicle for transporting passengers; which also carries its own engine or motor. Most definitions of the term specify automobiles are designed to run primarily on roads‚ to have . seating for one to eight people‚ to typically have four wheels‚ and to be constructed principally for the transport of people rather than goods. Automobile comes via the French language‚ from the Greek auto [self] and mobiles [moving]; meaning a vehicle that

A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field
