... 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. Herein, an approach ... Even so, the design problem is nontrivial and provides an organized and systematic approach to machine design. This approach may be readily extended to include a wide variety of design considerations. The ... considerations. The machine design problem is made easier if given context. To this end, our problem is to design a three-phase, wye-connected, permanent-magnet ac machine to produce a desired...
