We will now discuss a more accurate and general equivalent circuit for the GEM system shown in Figs. 2.1a and 2.2. The target of this section is to derive more general and instructive magnetic circuit equations in order to achieve better engineering analytical methods for real mini electro-machine systems and to develop a more instructive and accurate computational approach for optimal system design. However, before the circuit equations are discussed, several technological aspects concerning a real slotwise magnetic core geometry needs to be characterized. In this section we will only briefly mention a general technique for classical analysis to obtain an mmf distribution which is practically close to sinusoidal, i.e. minimizing high spatial harmonics at the slotwise geometry. In Chapter 6, we will discuss iii more detail a precise discrete sinusoidal coil theory for designing with high accuracy and resolution sin-cos transformers, encoders, and resolvers. The generalization and higher accuracy computational design approach discussed later will involve incorporating in magnetic circuit equations the practical significant factors such as core B(H) characteristics, air gap irregularities, different types of coil mmf distributions, thin-walled cylinder rotor and squirrel wheel rotor equivalent circuits, and other design parameters
