Abstract
The chief topic in this paper concerns field structures in synchronous machines which simulate an anisotropic material, which have a greater permeance in the direct axis than in the quadrature axis. Superficial anisotropy is also considered alone and in combination with internal anisotropy. It is shown that an increase in reluctance torque may be secured by due attention to both superficial and internal construction. No new method of securing superficial anisotropy is given but, in a brief discussion, a short method of estimating it is proposed. The internal structure proposed for analysis, is a slitted rotor core simulating an anisotropic material.Keywords
