Chapter 27 - Electric Machines Theory of Operation and Potential for Advances Using Carbon Nanotube Wire and Soft Magnetic Composite Materials

Abstract

Electric machines and other electromechanical systems are utilized in many components in our everyday lives. Electric power generation is also very important in aerospace and defense systems. Setting up remote power systems on temporary air bases or spacecraft and space stations are examples of power generation systems. Electric, mechanical, and aerospace engineers should have basic knowledge of electromechanical devices in order to design electric machines of the future and to integrate these machines into larger systems. Specifically, the use of new carbon nanotube electric and thermal conductors and soft magnetic composite (SMC) materials in electromechanical devices is an upcoming new technology for the design of lightweight airborne vehicles such as helicopters, drones, and future hybrid or total electric cars. This chapter is intended to familiarize engineers with the different types of electric machines and their applications. The chapter will also explore the potential use of carbon nanotube and SMC materials in manufacturing lighter and more efficient electromechanical devices.
