Experimental study of high speed induction motor varying rotor core construction

Abstract

An experimental study of a high-speed induction motor with various rotor constructions is described. The electrical characteristics of a solid-core-type induction motor are inferior to those of a laminated-core-type motor. A new equivalent circuit for a solid-core-type motor is presented. The behavior of the solid core as secondary conductors is considered. The stray load loss with respect to the rotor construction and the influence of the supply frequency are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
