... (15.3-3) FORMULATION OF DESIGN PROBLEM 609 15.9.  FORMULATION OF DESIGN PROBLEM At this point, we are ready to consider the design of the machine. There are many ways to formulate the design problem. ... INTRODUCTION The majority of this text concerns the analysis of electric machinery and drive systems. The focus of this chapter is the use of these concepts for design. In particular, the design of a permanent-magnet ... the parameters and performance data from machine design 100 (the 100th machine design in order of increasing mass).
