This paper reports a study of the electromechanical principles involved in a variable capacitance micro-motor (VCM). It examines the principle of energy conversion for the machine. It also explores the electrostatic force analysis using coenergy method and Maxwell stress tensor method which can be used to estimate force densities in the air gap. A multi-level inverter has been designed and simulated...
Switched reluctance (SR) drives manifest an effective integration of electromechanical energy conversion devices and modern power electronics technology. Although SR drives can be operated using a unidirectional inverter, recent studies have shown that a bipolar excitation, in which a short flux path between two adjacent phases is maintained, can provide superior performance under multi-phase excitation...
