Abstract :
The internal design of unlaminated-rotor induction machines is investigated, with particular reference to hollow shell rotors either with or without a central steel web. The performance of these designs is explained in terms of flux-penetration, eddy-current and endeffect factors, and the theory is substantiated by measurements of machine performance and flux distribution. The examples given show that the webbed rotors can be designed to give either high torque or low inertia.
