How Tesla Will Change The World — Wait But Why
How an AC Induction Motor Works Blue Box One of the two common types of electric motor is the AC induction motor (that’s what Tesla cars use). AC stands for alternating current,14 and induction means there’s no physical contact between the rotor and the stator—electricity in the stator generates a rotating magnetic field which enters the rotor through electrical induction and causes it
