A Parameterized Nonlinear Magnetic Equivalent Circuit for Design and Fast Analysis of Radial Flux Magnetic Gears
<|reference_start|>A Parameterized Nonlinear Magnetic Equivalent Circuit for Design and Fast Analysis of Radial Flux Magnetic Gears: Magnetic gears offer advantages over mechanical gears, including contactless power transfer, but require robust analysis tools for optimization and commercialization. This study proposes a rapid and accurate 2D nonlinear magnetic equivalent circuit (MEC) model for radial flux magnetic gears (RFMG). The model, featuring a parameterized gear geometry and adjustable flux tube distribution, accommodates nonlinear effects like magnetic saturation while maintaining quick simulation times. Comparison with a nonlinear finite element analysis (FEA) model demonstrates the MEC's accuracy in torque and flux density predictions across diverse designs. Additionally, a parametric optimization study of 140,000 designs confirms the MEC's high accuracy, achieving close agreement with FEA torque predictions, with simulations running up to 100 times faster. Finally, the MEC shows good agreement with 2D FEA for a prototype RFMG.<|reference_end|>
