By observation of electrical resonances, switched reluctance drives can be controlled without position sensor. The range of resonance frequencies is defined by the position-dependent phase inductance and a parasitic capacitance, mainly associated with the converter switches. In this paper, an analytical model is used to predict the aligned resonance frequency, taking into account material and g...

This letter analyzes and presents the motor startup problem when a split-link converter is used for switched reluctance motor drives. A new control algorithm to solve this problem is presented in this paper, as well as the calculation of the split-link capacitance required during normal operation.

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

The reluctance synchronous motor (RSM) is a machine working on the basis of development of reluctance torque development. The rotor configuration with the salient poles is made from the rotor of asynchronous motor if some rotor teeth are symmetrically removed (mill out). A different air gap in d and q axis enables development of a reluctance torque. The rotor cage is asymmetrical because some b...

In this study, radial forces that create noise, which is a fundamental problem in Switched Reluctance Motor (SRM), are investigated. Since force causes stator vibrations and noise caused by magnetic field, new switched reluctance motor model with increased rotor poles has been designed order to reduce the acting on poles. addition, structure high torque low leakage flux compared conventional wi...
