Abstract

The increasing need for electric/hybrid electric vehicles to compete with fossil fuel-powered cars has led to new requirements and designs of the electric motor. Non-grain oriented steel (NOES) is primarily used within the electric motor to form both stator and rotor sections (dependent on design) a...
