Time-Stepping Finite Element Method for Integrated Motor Propulsor with Solid-Rotor

In this study, we design a novel Integrated Motor Propulsor (IMP) which worked underwater for propelling. The motor in this IMP was PM motor employing Halbach array and solid rotor; and a fieldcircuit-motion coupled time-stepping Finite Element Analysis (FEA) model is presented for analyzing this             = = = ∂ ∂ = ∂ ∂ − = ∂ ∂ = = − =     ∂ ∂ ∂ ∂ +   ∂ ∂ ∂ ∂
