Features: This book is divided into eight chapters, with the following content description:
Chapter 1 classifies claw pole motors into claw pole motors and claw pole generators, and introduces the structures of several types of claw pole motors based on this classification.
Chapter 2 covers the classification of AC generators, the structure of automotive claw pole generators, and their working principles.
Chapter 3 elaborates on the calculation of the electromagnetic field and various parameters of automotive claw pole generators using different methods.
Chapter 4 provides detailed formulas for the energy perturbation method, calculates the winding inductance of claw pole generators, and introduces how to obtain the commutation inductance using excitation current and armature voltage methods.
Chapter 5 discusses the theoretical analysis and calculation of electromagnetic force, electromagnetic noise, and stator displacement in automotive claw pole generators.
Chapter 6 introduces the calculation of eddy currents and eddy current losses in automotive claw pole generators using three-dimensional finite element methods, and derives the generator's efficiency from the loss calculations.
Chapter 7 presents the structure of an under-researched hybrid excitation claw pole generator for automobiles and calculates the generator's parameters using three-dimensional finite element methods and three-dimensional equivalent magnetic network methods.
Chapter 8 introduces an international research-based automotive claw pole generator slip model sensor, a dual-voltage claw pole generator system, and a new control system for speed-generating control methods. It concludes with an overview of the current status and development trends of automotive claw pole generator control systems.
