|a Sažetak na hrvatskom: Proučena je dostupna literaturu o razlomljenim namotima za strojeve s trajnim magnetima te su obrađene određene podvrste razlomljenih namota. Određeni su analitički izrazi za izračun faktora namota, tablice namota, zvijezde napona, minimalnog mogućeg kuta skošenja i maksimalnog dozvoljenog broja
paralelnih grana. Uspoređeni su namoti s obzirom na harmoničko rasipanje, radijalne sile, buku i gubitke u rotoru. Izrađena je Matlab skripta i korisničko sučelje za izračun navedenih karakteristika namota.

|a Sažetak na engleskom: This paper presents some design considerations for
synchronous machines characterized by a fractional number of
slots per pole per phase. The main advantage of this configuration
is a smooth torque, which is due to the elimination of periodicity between slots and poles. A second advantage is a higher
fault-tolerant capability, making the machine able to work even
in faulty conditions. However, the fractional-slot configuration
presents a high content of MMF harmonics that may cause an
unbalanced saturation and thus an unbearable torque ripple. A
method to design fractional-slot machines is illustrated in this
paper, including double-layer and single-layer windings. The analytical computation is extended to determine the harmonics of
MMF distribution. Their effect is highlighted in isotropic as well
as anisotropic machines. Finally, some considerations are reported
to avoid unsuitable configurations.
