The Impedance Matrix of the Induction Machine Having a General Stator-winding Axis and its Torque Formula

概要

Such a stator-winding as every phase of it is not always placed apart symmetrically in space and its effective turns are not necessarily equal to others is named here as 'a general stator-winding axis'. In this paper primarily the impeadance matrix (Z)and torque formula of any phase induction machine having a general asymmetrical stator-winding axis are derived by solving the differential equations. To calculate the various characteristics of the above machine from these results is well-known, so I have omitted its description here. Therefore I believe this paper gives an analytical method on the above machine. Secondly (Z) is reconsidered by two revolutions theory of the magnetic field and the theory of equivalent circuit of a single-phase induction motor so that the physical meanings of the elements of (Z) may be understood well. Thirdly it is described how the three-phase symmetrical coordinate method be extended so as to be adaptable to three-phase asymmetrical winding axis.
