Modelling and Analysis of a Piezoelectric Annular Stator Structure for a New In-situ Dynamic Balance Regulator

چکیده
This paper presents the modelling and analysis of a piezoelectric annular stator structure for a new in-situ dynamic balance regulator which is driven by the in-plane bending vibration of the stator. The mathematical model for the in-plane vibration is first developed using an analytical method to determine the theoretical excitation frequency. The excitation modes and structural parameters are then analysed to optimise the performance of the stator. To improve the efficiency of the design and to achieve precise control, a semianalytical electromechanical coupling model is developed using the dynamic substructure method and the finite element method. The model is verified in preliminary tests.

In this paper, a new structure of axial flux switched reluctance motors (AFSRMs) is proposed. Different combinations of rotors and stators affect motor torque and its performance. In this regard, changing the stator structure of the AFSRM leads to better results for torque and magnetic flux. The advantages of the proposed structure are short flux path, segmental rotor with improved flux density...
