Vibration analysis of a linear switched reluctance actuator

The main drawback of switched reluctance machines acceptance is the acoustic noise produced. Research efforts to minimize vibrations in this type of electric machines concentrate mainly on the rotational configuration and only a few works can be found focusing on linear actuators. This paper presents the results of finite elements analysis of vibration frequencies for a linear switched reluctance actuator. The results obtained serve as reference and support for experimental modal analysis and characterization of vibrations and acoustic noise in this type of machines.
