Abstract

This paper forms part of a broader study on the design optimization of a high speed switched reluctance motor for automotive traction applications. Due to the high speed operation and resulting high electrical frequency, it is of extreme importance that the different loss components of this motor are accurately calculated. In this study, several effects are observed that influence the accurate measurement of the core loss data used in the calculation of the iron loss in the motor design. It is shown that especially at high frequency and flux density, the loss measurement can be significantly influenced by effects such as temperature, winding AC loss, flux density saturation, and flux waveform shape. The proposed fundamental frequency of... (More)

This paper forms part of a broader study on the design optimization of a high speed switched reluctance motor for automotive traction applications. Due to the high speed operation and resulting high electrical frequency, it is of extreme importance that the different loss components of this motor are accurately calculated. In this study, several effects are observed that influence the accurate measurement of the core loss data used in the calculation of the iron loss in the motor design. It is shown that especially at high frequency and flux density, the loss measurement can be significantly influenced by effects such as temperature, winding AC loss, flux density saturation, and flux waveform shape. The proposed fundamental frequency of the case study motor is 4 kHz, and flux density values of up to 2 T can be obtained under certain load conditions.
