Abstract
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.
Abstract (english)
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.
