   <dc:description>The improvements obtained on the torque with low currents using rotor with spiral sheets are analyzed&#xd;
in this paper. To have a complete study, several rotors and stators have been built to verify the electromagnetic&#xd;
variations on the three-phase asynchronous motors where they combine different constructive&#xd;
and mechanical characteristics of the related elements: changing inertias, constructive materials, and the&#xd;
geometrical shapes and disposition of the sheets. These different types of motors have been first tested in&#xd;
the laboratory, then, are simulated using computer aided tools (Matlab–Simulink). In particular four stators&#xd;
(1000, 1500, 1500-type A, and 3000 rpm) having the same constructive parameters, have been tested&#xd;
with the following rotors: solid rotor, solid rotor with diamagnetic rings, drag cup, and simple and double&#xd;
squirrel cage rotor. All these results have been compared to those obtained with the seven variants of&#xd;
spiral sheet rotor, presented in this paper.</dc:description>
