AC Electrical Machine Torque Harmonics 10-21
10.7 Reluctant Torques
ese reluctant torques are oen considered concerning salient synchronous machines or reluctance
ones [19–21]. In this chapter, these reluctant torques will be expressed considering an induction machine,
taking the slotting eect into account and assuming sinusoidal the stator and rotor currents.
10.7.1 Machine Modeling
e Equations 10.43 through 10.47 are always valid, only Λ, the permeance per area unit, changes.
Introducing the integers k
s
and k
r
, which take all the values between −∞ and +∞, Λ can be written, for
a 2-pole machine, as follows [2,22]:
Λ Λ= +
=−∞
+∞
=−∞
+∞ ...
