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

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

Tesla motors has taken a different approach in EV technology and I think its paying off. Though the challenges from the establish competition would be thrown in coming years and to maintain the differentiation would be tough which will reduce the capability to charge the premiums‚ hence the scale needs to be achieved for sustainability; the mass adoptability of EV would be the key and for that the Auto manufacturers needs to work hard under the federal support. Tesla Motors has positioned
