“…By moving the rotor from the full‐alignment position to the non‐alignment position, the capacitance characteristic is obtained and the 4×4 matrix is formed. An LCZ metre is used to measure the capacitance characteristic [23,24]. The measurement procedure involves changing the position of the rotor electrodes from the non‐alignment position with the stator electrodes to the full alignment position and all the capacitance values are accurately measured.…”

“…In references [16,21], modelling of a linear variable capacitance machine (VCM) machine is described considering the effects of capacitance imbalance, while the capacitance matrix is obtained both through numerical methods and the experimental measurements (EXP). Also, several simple and useful methods are introduced in [22][23][24] for measuring the self and mutual capacitances of the VCM machines experimentally. In this regard, finite element (FE)-based simulations have been well recognized as the other powerful conventional methodologies for evaluating all elements of the capacitance matrix [25][26][27].…”

This article describes a detailed analytical method for obtaining the capacitance matrix elements in variable capacitance synchronous machines (VCSMs). The analytical modelling approach is performed by introducing a decentralized sinusoidal distribution of the stator/rotor electrodes and involves obtaining the capacitance matrix elements based on the electro motive force distribution in the air gap and calculating the induced electric charge in the stator/rotor electrode surfaces. The proposed analytical formulas are valid for both radial-field and axial-field VCSM structures. The analytical model is evaluated and well verified through analysing a multi-stack axial-field VCSM using 3D finite element simulation. Furthermore, a prototype of the VCSM is manufactured and tested to validate the results obtained from the proposed analytical model and finite element method simulations. Based on the results, the proposed model and analytical formulas are able to accurately estimate the capacitance matrix elements of the VCSMs. Ahmad Darabi is the co-author of this study.
