About this book

This book provides an insight into the design, modeling, control, and application of multiphase hybrid permanent magnet machines for electrified powertrains in electric and hybrid electric vehicles. The authors present an overview of electric and hybrid electric vehicles, hybrid electric machine topologies, hybrid permanent magnet (HPM) machine design, multiphase hybrid machines, operation of multiphase generators in series hybrid electric vehicles (SHEV), and machine hardware build-up and testing. Readers will gain an understanding of multiphase machine configuration, their design, control, and recent applications, along with the benefits they provide, and learn general design steps, prototyping, and hardware build-up processes of multiphase electric machines.

Multiphase Hybrid Electric Machines: Applications for Electrified Powertrains will be a valuable reference for undergraduate and graduate students, researchers, and practicing engineers, working on electric/hybrid electric vehicles, as well as electric machine applications in renewable energy systems specifically wind turbines, HVAC systems, robotics, and aerospace industry.

Chapter 1. General Electric Machine Theory
Abstract
This chapter provides a review of the general theory of electric machines. It discusses the principles of electric machine operation, magnetic modeling, and characteristics of materials. Various classical electric machine topologies, including brushed DC, and different AC machines are discussed.

Chapter 3. Hybrid Permanent Magnet Machine Design
Abstract
In this chapter, a HPM machine topology is selected and analyzed in more detail in terms of its machine geometry, excitation field technique, back-EMF per coil, back-EMF per phase, and developed electromagnetic torque for both no-load and on-load characteristic cases. The selected HPM machine topology consists of two different synchronous machines, a PM and a WF machine coupled on the same rotor shaft. Each of these machines and their combined topology will be addressed.

Chapter 4. Multiphase HPM Generator Systems
Abstract
In this chapter, an overview of multiphase electric machines is discussed. Alternating and rectified DC output voltage waveforms of three- and nine-phase HPM generators with an associated power electronics rectification stage are presented. Comparison of three- and two nine-phase machine winding schemes in terms of winding factor is studied. Two nine-phase HPM generators with different numbers of stator turns are compared for their terminal and DC-link output power and the quality of the generated DC output voltage. In addition, sensitivity analysis based on machine synchronous inductance for three- and nine-phase configurations with varying load conditions are performed. Finally, a loss comparison between the HPM and PM machines and their rectification systems for three- and nine-phase winding configurations is presented.

Chapter 5. Electric and Hybrid Electric Powertrains
Abstract
In this chapter, an overview of EVs and HEVs, their powertrain schemes, and onboard energy sources is presented. Different battery technologies are discussed, and in the case of hybrid electric vehicles, the feasibility of disconnecting the internal combustion engine (ICE) from the electric drivetrain is studied. Driving range, fuel economy, and emissions are evaluated over different driving cycles and at different vehicle powertrain hybridization ratios (HRs). The HR is an important factor that defines the ratio of ICE to battery system energy output for a hybrid electric vehicle.

Chapter 6. Operation and Characterization of Multiphase HPM Generator in SHEV Powertrain
Abstract
This chapter discusses a dynamic model of vehicle powertrain while considering a load demand. The vehicle powertrain includes a hybrid permanent magnet (HPM) generator integrated into an internal combustion engine (ICE) in a series hybrid electric vehicle. The ICE/HPM generator output power control scheme is modeled while maintaining ICE efficiency within its optimal region. Several operating scenarios for the HPM generator excitation scheme are assessed, and the HPM generator is characterized utilizing a 32-phase brushless excitation scheme. Different cases, such as normal, boost, and buck functionality of HPM machine operation, are analyzed, and a choice of the most appropriate operation mode has been selected to regulate the total back-EMF via a WF excitation current control.
