An analysis is given from fundamental principles of the performance of induction machines having smooth thick-cylinder rotors, both for polyphase and single-phase conditions. Flux and current distributions are obtained together with torque/speed characteristics and numerical values computed from the derived formulae. Experimental results obtained from a specially constructed thick-walled rotor machine and from a single-sided linear machine are given for comparison.
