Reduction in the Cogging Torques in the DCEFSM Motor by Changing the Geometry of the Rotor Teeth

“…• choice of the appropriate angular span of magnets in machines excited by permanent magnets [2,[5][6][7][8]; • making excitation magnets that are skewed [2,5]; • desymmetrization of the arrangement of magnets in the machine [4,9,10]; • choice of the shape of the magnets on the side of the air gap [7]; • making ferromagnetic pole pieces for excitation magnets with an appropriately selected angular span [6]; • construction of a machine with magnets embedded in the rotor ferromagnetic (IPMSM) [7]; • appropriate choice of the angular span of the stator or rotor teeth [11][12][13];…”

“…• appropriate choice of the angular span of the rotor poles (teeth) in reluctance machines [14,15]; • making slots in the stator or rotor that are skewed [3,4,11,[14][15][16][17]; • desymmetrization of the angular arrangement of rotor poles (teeth) in reluctance machines [4,10,11]; • choice of the shape of the face of the poles/teeth of the stator or rotor [18,19]; • making cuts in the stator teeth or inserting additional teeth [7,15,17]; • using an appropriate current power supply [12,20,21].…”
