The electromagnetic field calculation of the switched reluctance motor

Performance of High-Speed 4/2 Switched Reluctance Motor

“…In this torque dead zone, selfstarting is impossible and mechanical vibration is very serious due to the high torque ripple. To reduce torque dead zone, some rotor types have been studies [4][5][6][7][8][9][10][11][12][13][14][15].…”

“…The air teeth are very small for adding a distributed flux path, and the small air teeth structure is difficult to realize in a practical system. 5 shows another rotor structure to obtain a wide torque region [13][14][15]. The inserted air hole can produce a saturated flux path and add additional reluctance.…”
