Summary:The first generation prototype electric vehicles were developed with DC machines, but eventually the industry switched to AC machines. Both permanent magnet (PM) and induction machine based electric powertrains are being produced for electric and hybrid vehicles. Currently, the most common type of electric machine used for production and prototype EV/HEVs is the interior PM synchronous machine (IPM). This machine has a higher power density because the rotor has no windings, only permanent magnets. The IPMs have excellent efficiencies and high power densities; the limited field weakening capability in conventional PM synchronous machines is overcome by having the magnets buried inside the rotor. Induction machines are used in some of the production electric vehicles. The induction machine technology is mature, the materials are readily available, and the production cost is relatively lower. However, these machines have limited constant power range and the efficiency is lower than that of a similarly sized comparable PM Machine
