The General Equations of A.C. Machines

  • Bernard Adkins

Any machine, other than those with commutators, consists of a set of coils for which voltage equations can be written in terms of self and mutual inductances and resistances. The machine however differs from a static circuit in that the coils are in relative motion and consequently that some of the inductances are functions of the relative position. The idealized synchronous machine of Fig. 1.3 has six coils and there are six voltage equations, in which many of the coefficients are periodic functions of the angle θ.
