Abstract
In recently published papers concerned with variable saturation in cylindrical rotor a.c.
machines, a cross-saturation effect was described, caused by variable saturation. Using the same
approximations as applied in the cited papers we will show that Faraday's law applied to
cylindrical rotor a.c. machines including variable saturation excludes any transformer effect that
links the mutually perpendicular axes of a general reference frame. In reality the induced
component voltages in the directions of coordinate axes are well defined by transformer and
rotational effects in agreement with Faraday's law, showing that the coordinate axes of the
applied general coordinate system, are magnetically independent
