A method of analysis is presented to obtain the three-dimensional distribution of electromagnetic fields in a solid rotor induction motor. Partial differential equations are established for these fields in the various regions of the machine. Velocity dependent boundary conditions are derived for application to interfaces between moving media. Field solutions are obtained by the method of separation of variables. Difficulties encountered in applying boundary conditions to the air gap solutions are described. Methods of satisfying stator surface conditions by means of general orthogonal sets of functions are discussed. Expressions for the machine torque are developed through the use of Poyntings Theorem. The relationships between two- and three-dimensional field distributions are discussed. Author
