The most elementary type of rotor for the polyphase induction machine is the solid-iron rotor, which offers advantages in ease of manufacture, in high torque per ampere at standstill, in withstanding high rotational stresses, and in operating in unusual environments. Since conventional induction machine theory has proven inadequate for such machines, the need has arisen for improved methods of investigation. It is the purpose of this paper to present an approximate three-dimensional nonlinear numerical analysis for the solid-rotor induction motor, based on magnetostatic assumptions and finite-difference iterative techniques.
