This paper proposes a new fast method to determine the entire flux-linkage characteristics of a switched reluctance machine (SRM), which are critical for performance estimation and advanced control of the machine. The proposed method mainly consists of two steps, namely, measuring and calculating. In the measuring step, the flux-linkage characteristics of(More)
Accurate static electromagnetic characteristics are essential basic data in the modeling of switched reluctance machine (SRM) for performance analysis and advanced control purposes. Because of the doubly salient structure and deep magnetic saturation, the electromagnetic characteristics of SRM have highly nonlinear relations with phase current and rotor(More)
This paper proposes a combined modeling method for switched reluctance machine (SRM) with few samples of flux linkage characteristics measured without rotor clamping devices and position sensors. The proposed method mainly consists of two steps, namely data reconstruction and characteristic description. In data reconstruction, the entire flux linkage(More)
In this paper, based on the comparisons of the stator pole flux density and phase current with corresponding rotary switched reluctance machine, the original design scheme of a 1-kW single-side switched reluctance linear launcher (SRLL) is obtained by a traditional method. To get higher efficiency and smaller force ripple, the genetic algorithm, which is(More)
This paper proposes a novel accurate position estimation method for switched reluctance machine (SRM). The method requires only the flux-linkage characteristics at two particular rotor positions, which can be conveniently measured by the torque-balanced method. The interval which takes these two positions as endpoints is selected as the optimal interval due(More)
A method to obtain the simulation model of the switched reluctance machine (SRM) is presented. First, the flux-linkage characteristics of a 1kW 3-phase 12/8-pole SRM are quickly measured without any rotor clamping device and position sensor, and few samples can be obtained. Then, to build the accurate simulation model of the machine with these few samples,(More)
This paper proposes a new decoupled analytical modeling method for switched reluctance machine (SRM). The flux linkage is represented by a second-order Fourier series, and the coefficients of the series are position dependent, which can be further expressed by another second-order Fourier series. The proposed method only needs 21 data points from five rotor(More)
