Comparison of Protection Requirements in IE2-, IE3-, and IE4-Class Motors

Autor: Anibal T. de Almeida, Fernando J. T. E. Ferreira, Benoit Leprettre

Publikováno v: IEEE Transactions on Industry Applications. 52:3603-3610

In this paper, an overview of the main motor features influencing the protection devices settings is presented, pointing out key differences between three-phase direct-on-line (DOL) motors of different efficiency classes. The results of experimental

A frequency demodulation approach to induction motor speed detection

Autor: Roy S. Colby, Zhi Gao, Benoit Leprettre, Larry A. Turner

Publikováno v: 2010 IEEE Energy Conversion Congress and Exposition.

Rotor slot harmonics are found in the stator current waveforms for most squirrel-cage induction motors. These harmonics are caused by the finite number of rotor slots in a motor, and their frequencies are inherently correlated with the motor's rotati
