Ghasan Khalil TARDEC ABSTRACT Electric dnve is finding applications in many new land-based systems, ranging from heavy armored vehicles to public transportation buses and automobiles. The development of these electric hve systems has been made possible, largely due to sigulticant advances in the design of motors, generators and power electronics. Wlnle these advances have allowed designers to proceed with the development of operational vehcles, further developments are now being considered for application to future land vehicle concepts, beyond the scope of present programs. The present paper discusses the issues associated with the development of new types of motors that are appropriate for the particular requirements of land vehicle traction. The paper also discusses new concepts for advanced solid-state power electronics, which will be required for future electric dnve vehicles. 1. INTRODUCTION Although electric dnve (ED) was conceived and applied to many types of automotive vehlcles for many years, interest in th~s form of propulsion lapsed and became moribund, except for small uthty vehicles, such as golf carts. With the past few years, there
