Generic torque-maximizing design methodology of surface permanent-magnet vernier machine

A surface permanent-magnet vernier machine (SPMVM) has a toothed-pole structure, and its highly nonlinear relationship between its dimensions and magnetic field makes its design cumbersome. This paper presents a generic design methodology for the machine which brings out its torque-maximizing structure in a convenient manner. Various suggestions concerning the design of the SPMVM are also set forth.
