Effect of Number of Stator Slots on the Starting Torque of a Line-Start Three-Phase Reluctance Motor with Double Rotor Cage Bars | IEEE Conference Publication | IEEE Xplore
This paper analyses the effect of number of stator slots on the starting torque of a three-phase Line-Start Synchronous Reluctance Motor (LS-SynRM) with double rotor cage bars. The analysis focuses on distributed three-phase windings housed in 24 stator-, 36 stator-and 48 stator-slot cores. The machines have been designed with the same dimensions and rotor specifications but with different number of turns per phase. A winding function approach is utilized to study the magnetomotive force (MMF) distribution of each stator winding configuration under full-load operation. The 2D Finite Element Analysis (FEA) under ac magnetic transient solution is used to simulate the flux-density and the torque characteristics, under full-load operation. The FEA results evidenced that all three LS-SynRMs stall for about ± 20 mSec at starting, before the acceleration begins. A prototype of the LS-SynRM with 36 slot is manufactured and tested. The results are within the simulated results.

US20140246943A1 - Optimum rotor skew angle for an electric machine - Google Patents
An electric machine includes a stator core defining a number of stator slots (S) extending along a longitudinal axis and angularly spaced about the longitudinal axis. The machine includes a rotor assembly rotatable relative to the stator core and defining first and second ends. The rotor assembly includes a plurality of laminations stacked between the first and second ends. Each respective one of the plurality of laminations defines a number of rotor slots (R) positioned along an outer periphery. A stator slot pitch is defined as 360 divided by the number of stator slots (S). A rotor slot pitch is defined as 360 divided by the number of rotor slots (R) in each respective one of the plurality of laminations. The laminations are skewed relative to each other. An optimal rotor skew angle is determined by the greater of the stator slot pitch and rotor slot pitch.
