To meet the demand of multiple power requirements, and enhance power utilization, a new type of dual-element electricity unit is designed in this study, which is a permanent magnet piston mechanical electric engine. Based on the analysis method of traditional internal combustion engines and linear generators, the working principle of the engine and the magnetic field distribution in the electrodynamic structure are analyzed, the machine dynamics model and electrodynamics model of the engine are established, then the theoretical evaluation is additionally established using finite elements. Based on this, an optimization model is constructed with the electrodynamic shape dimension as the optimization variable, with the intention of growing the output power. The optimization of the engine electrodynamic shape is executed via the use of the finite aspect approach and the NLPQL optimization algorithm integrated. The results show that the optimized engine output electricity expanded to 8.40 w, which is 18.81% greater than before optimization. An experimental prototype is developed, and the output voltage of the prototype is measured to verify the precept and overall performance of the new structure.

“…The conception of virtual SPM motor is useful for the analysis of IPM motor [3]- [5]. Akiki et al proposed a saturated analytical model based on Ampere's theorem and flux conservation law, which considers both stator and rotor saturation [12]. Farshadnia formulated the saturation level at different rotor regions using the rotor geometry and the nonlinear B-H curve, and obtained the equivalent air-gap function to calculate the air-gap field of IPM motors with the non-homogeneously saturated rotor [13].…”

A hybrid field model (HFM) based on the combination of magnetic equivalent circuit (MEC) and exact conformal mapping (ECM) is developed to calculate the open-circuit field of interior permanent-magnet (IPM) motor. In the proposed HFM, the IPM and iron saturation is transformed into equivalent current on the rotor surface and stator bore. ECM can calculate the air-gap field analytically using the equivalent current. Once the air-gap field is obtained, the MEC in the iron region can be solved and gives the new value of equivalent current, which forms a calculation loop. Hence, iterative solving process is required to determine the equivalent current and iron permeability in the rotor and stator. In order to verify the proposed model, both finite element (FE) analysis and experiment are performed on IPM motors with V-type rotor and conventional "-" type rotor. Their results demonstrate the high accuracy of HFM.

This paper presents a stepwise optimal design (SOD) for an interior permanent magnet synchronous motor (IPMSM) applied to electric vehicle traction, which sequentially utilizes a magnetic equivalent circuit (MEC), finite element analysis (FEA), and a newly proposed optimization algorithm. The design of an IPMSM for the traction motor of a fuel cell electric vehicle (FCEV) is challenging due to its tough requirements, such as high torque density, high efficiency, and low torque ripple; as a result, an iterative trial and error process is required. However, FEA, which is the most generally used analysis technique for electric machine design, has a drawback in terms of the analysis time required when being applied to the entire design process. In this regard, the proposed SOD is presented, which consists of initial, detailed, and optimal design stages, to design an IPMSM with a reasonable design time.
