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

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,
