AFPM Machines With Iron Cores

In Chapter 2, principles of operation, topologies and fundamental equations of a broad family of AFPM machines were discussed. In this chapter, the focus is on those types of AFPM machines that make use of the stator and rotor ferromagnetic cores. The AFPM machines with ferromagnetic cores are designed both as single-sided and double-sided. The stator core can be fabricated using either laminated steels or SMC powders. General equations given in Chapter 2 for the performance calculations will be developed further and adjusted to the construction of AFPM machines with ferromagnetic cores. Application of the FEM analysis to performance calculations is also emphasized.
