Doubly-Excited Machines (Nature of Inductance Changes)

Machines with One Winding on the Stator and One winding on the Rotor The majority of electrical machinery that constitute the backbone of the industry (synchronous generators, induction motors and DC machines) belong to this group. In this kind of … Continue reading

Singly-Excited Machines (Nature of Excitation Currents)

In the former post of singly-excited machines, some elementary machines were studied where their self inductances were functions of the rotor position and would change periodically with the rotor rotation. Now we study the conditions under which the currentsĀ ij and … Continue reading
