Lamination Core Losses in Motors With Nonsinusoidal Excitation With Particular Reference to PWM and SRM Excitation Waveforms

Abstract: The effects of varying the modulation index and the switching frequency on steel lamination core losses when excited with pulse width modulated waveforms are first investigated. A switched reluctance motor flux model is also developed and flux waveforms for different parts of the machine are synthesized. Using these flux waveforms, the paper presents the loss trend inside a switched reluctance machine, showing the core loss variation of the machine. The rotor was found to incur higher losses than any other par… Show more

“…This also ties in with the recent increase in the interests in measurements in the saturation range [2][3][4][5]. Although magnetic saturation has not been the subject of interest in the past, modern techniques in control and operation of rotating machines has lead to the development of new methods for characterizing these materials [6].…”

“…Los variadores de frecuencia son equipos nuevos que se han venido implementando para variar la velocidad de los motores eléctricos [65], su uso se ha vuelto muy común pues es posible realizar fácilmente acciones de control sobre los motores eléctricos. En los procesos industriales se han podido implementar procesos rápidos y eficientes con ayuda de los variadores de frecuencia.…”

“…La asimetría y la distorsión de la tensión de alimentación son las causas más comunes que alteran el comportamiento y disminuyen la vida útil de los motores eléctricos. La asimetría y la distorsión de la tensión de alimentación pueden ser causadas debido a la conexión de variadores de frecuencia [65] y [66], o por cargas no eficientes conectadas en paralelo con los motores.…”
