“…For this reason, the maximum field weakening has not been studied in the publications. An exception is [5], wherein the fractional slot winding has reached a field weakening range of 6.2:1, in contrast to 4:1 for the distributed winding. More important are the losses in the field weakening range.…”

“…A very low cogging torque can also be achieved with fractional slot windings by a suitable slot-/pole-ratio. This is shown in [5], [6] and [10]. In contrast, [11] shows that an unsuitable choice of slot-/pole-ratio can increase the cogging torque of the fractional slot winding over a distributed winding.…”

“…In [5] three machines with the same installation space are compared. Due to the winding heads the fractional slot winding has a higher active length and overall torque density.…”

“…More important are the losses in the field weakening range. [8], [6], [7], [12], [11] and [5] have examined the losses in the base speed and field weakening range. The iron and eddy current losses in the permanent magnets at the base speed range are usually of the same order.…”

“…In addition, arrangements can be made to reduce the additional harmonics and losses considerably with a suitable choice of the winding design. In this context, many scientific publications have been released which compare fractional slot windings with distributed windings [5], [6]. The focus usually lies on power density, field-weakening range and losses of both winding topologies.…”

In this paper the interaction between rotors with interior permanent magnets (IPM) and different winding topologies is analyzed. A distinction is made between distributed winding and fractional slot winding. Four designs with different winding topology will be analyzed concerning their reluctance. It can be shown that not only the geometry of the stator and rotor affect the reluctance torque. The winding topology, respectively the current load spectrum is of significant relevance. It can be inferred that not every winding topology can be used effectively with IPM rotors. Certain orders in the harmonic spectrum of the winding reduce the reluctance torque. By using a current load model to exclude stator geometry effects that impact the reluctance, it can be shown that a higher reluctance torque can be achieved through the suppression of certain harmonics.
