The paper suggests a circuit for replacing the magnetic circuit of a reactive electric machine with an anisotropic magnetic conductivity of a rotor, which serves as a basis for the obtained analytical dependences that allow determining the longitudinal and transverse magnetic conductivities of a two-pole reactive machine with anisotropic magnetic conductivity of the rotor with account for the fixing recess and the non-magnetic inter-pole gap. It also presents the results of comparison of two types of a reactive machine rotor production using longitudinal rotor lashing (ALA) and transverse rotor blending (TLA) by the coefficient of transverse magnetic conductivity. The presented mathematical description can be used to construct a technique to desig a reactive electric machine with an anisotropic magnetic rotor conductivity with longitudinal batch packing of rotor pole packs (ALA). The outcomes of the study prove that the mounting notch and the inter-pole air gap significantly reduce the transverse magnetic conductivity of the machine and, therefore, improve its efficiency.
