Abstract

THIS PAPER IS FOCUSED ON ELECTRICAL VEHICLES. SOME ASPECTS OF THEIR HISTORY AND MARKET EVOLUTION IS PRESENTED. NOWDAYS THE ELECTRICAL VEHICLES HAVE ALMOST 2% OF CAR WORLD SALES, CONCENTRED MAINLY IN DEVELOPED COUNTRIES. SOME CHARACTERISTICS OF ELECTRIC VEHICLE MOTORS ARE CITED AND IS EMPHASIZED THAT ELECTRIC STEELS APPLIED TO MOTOR CORES NEED TO HAVE SPECIFIC REQUIREMENTS WHICH ARE HIGH MAGNETIC PERMEABILITY, HIGH SATURATION INDUCTION, VERY LOW CORE LOSS, ADEQUATE MECHANICAL RESISTANCE AND GOOD PUNCHABILITY. FINALLY IT WAS MENTIONED THAT THE WORLD'S LEADING STEELMAKERS ALREADY OFFER STEELS WITH ALL THE REQUIREMENTS SUITABLE FOR ELECTRIC CAR MOTORS
