Interior Permanent Magnet Machine(IPMM)Technology: Optimization and Analysis of the Segmented IPMM with Wide Constant Power Speed Range(CPSR)

The Permanent Magnet machine is the natural choice of many niche drive applications because of their higher efficiency and compact size. Among various types of PM machines, the Interior Permanent Magnet Machine (IPMM) is gaining popularity in many applications because of its robust rotor and prospect of wider CPSR. However, the design and control of the IPM machine are mentioned in many PM machine technology books merely as a variation of the conventional PM machines which is inadequate for professionals involve in development of the IPMM.This book addresses the issue by starting with the review of the existing IPMM technology and then leading to the optimization process for developing a new prototype based on a particular application such as the Integrated Starter Alternator (ISA) for automobile. The analysis of this new design should be useful as a case study for researchers, academic, professionals or anyone else who is engaged in development of the IPM machine.
