The use of concentrated windings have been gaining popularity for use in permanent magnet machines. Here, the authors have attempted to implement concentrated non-overlapping windings (CNW) with an interior permanent magnet (IPM) rotor. This paper illustrates general procedures for the derivation of machine geometry, material choices as well as thermal considerations for designing IPM machines with...
This paper illustrates a general design process used for implementing non-overlapping concentrated windings in an interior permanent magnet (IPM) machine for field weakening applications. This design process was verified by finite element analysis (FEA) of a 18-slot, 14-pole model. The optimization process of torque and field weakening performance resulted in a design with thin inter-pole link sections...
The interior permanent magnet (IPM) machine is generally analysed with two axes theory. Machine parameters such as d- and q-axes inductances are needed for performance analysis as well as for controller design. So far no method appears to have been standardized to determine d- and q-axes inductances of the IPM machine. Normally, the classical methods available for the conventional salient pole synchronous...
