Induction motors with copper rotor: a new opportunity for increasing motor efficiency

ABSTRACT The copper rotor induction motor (CURIM) was recently introduced because it has lower rotor fusion losses than the aluminum rotor (ALRIM). Furthermore, with CURIM, it is easier to reach IE4 and IE5 efficiency levels. The CURIM is advantageous for compact motors, escalators, and electric vehicle applications. However, CURIMs present slip, power factor, temperature increase,

Use Of High Temperature Die Material & Hot Dies For High Pressure Die Casting Pure Copper & Copper Alloys

Abstract Little use has been made of pressure die casting for the manufacture of copper or copper alloy parts due in large part to poor economics resulting from short die life in casting these high melting metals. A research program initiated in 1997 was driven by the promise of a signifi cant increase in the
