Vibration Reduction Control of Switched Reluctance Machine

Switched reluctance machine vibration reduction using a vectorial piezoelectric actuator control

This paper deals with an original approach of the Switched Reluctance Machine (SRM) control for the purpose of reducing stator vibrations. Two combined approaches are studied in the aim of reducing the vibratory acceleration generated and thus the acoustic noise. The first one is based on a sinusoidal control of the magnetic phase current and the second one, on an optimal control of piezoelectr...

Vibration Analysis of Tapered Pole Linear Switched Reluctance Machine

Vibration analysis and control in linear switched reluctance motor

Vibration is one of the major drawbacks of Linear Switched Reluctance Motor (LSRM). Two design techniques to reduce vibration in the LSRM are proposed. A detailed mathematical approach for calculating natural frequency has been outlined. Different techniques to predict the vibration frequencies are analyzed using ANSYS software. The analyzed structures are compared by using experimental and sim...

Flywheel Generator with Switched Reluctance Machine

This paper presents a flywheel energy storage system, which uses a switched reluctance motor/generator. It is shown how this device can be used either together with a DVR or alone in order to attenuate the effects of voltage sags and short interruptions. In order to improve the system efficiency, some design alternatives are presented. Finite elements analyses results, validated against laborat...

Comments on Switched Reluctance Machine Mathematical Model

In the paper the main analytical models of the switched reluctance (SR) machine are presented, based on geometry data, magnetic equivalent circuits and finite element (FEM) analysis results. In each case a representative example is given and finally the advantages and the weak points of each type of model are evinced.
