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.

Stator Slots - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. The document summarizes the design of the stator for an induction motor. It describes how the stator consists of a laminated core with slots for windings and an outer cylindrical frame. It discusses the different types of stator slots including open, semiclosed, and tapered slots and factors to consider when selecting the number and size of slots such as power factor, assembly difficulty, and flux density. It also covers calculating the depth of the stator core based on the desired flux density in the core.

Cogging torque reduction method of the surface-mounted permanent magnet motor
The essence of the cogging torque problem of permanent magnet motors is that when the stator structure is embedded in the armature winding, slots formed on the inner surface of the stator, then directly enhance the motor torque ripple phenomenon operation and cause serious interference. The cogging
