Abstract

The rerated motor has the capability to provide its nominal torque at high speeds, increasing its shaft power while keeping its mass constant by increasing the applied frequency and spinning, the motor faster. The rerated induction machine has features such as high-power density, high efficiency, rugged constructions and manageable failure behavior in traction applications. This technique has been applied to 12.4 and 4.13N.m induction machines and showed that the rerated induction machines are capable of competing with permanent-magnet machines and can act as a practical method for motor mass reduction and efficiency improvement in traction applications. The rerating can increase the efficiency of a machine operated at nominal torque in a higher-speed range.
