Hybrid Electric Vehicles (HEV) was become prevalent and widely used since last few years. Within the HEV, the best candidate for electric-propulsion system is Interior Permanent Magnet Synchronous Motor (IPMSM). Despite of fine operation, constant state of flux and high cost due to limited and expensive rare-earth magnet price, alternative to the IPMSM was at desirable state. HEFSM was identified as new candidate of electric-propulsion system for HEV. HEFSM utilized both Permanent Magnet (PM) as primary excitation and Field Excitation Coil (FEC) as secondary excitation to produce flux. As such variable and high flux control capabilities make HEFSM more attractive. Thus HEFSM have the potential in improving torque and power density. On top of that, both PM and FEC was located at stator which make HEFSM become more robust and easy to design compared to the IPMSM. In this study, different model using 6 slot and various pole of HEFSM were designed using Geometry Editor in JMAG Designer Version 13. Simulation on the each model were completed. The measurement of HEFSM initial performance is critical to understand the condition and reaction of each model. Thus analysis on the performance of each model based 2D finite element analysis (FEA) were performed at no-load and at load condition. Among performance analysis for HEFSM at no-load are UVW coil test, flux distribution and cogging torque. At load condition, each model of HEFSM were introduced by varied armature current densities (Ja) and FEC current densities (Je) from 0 to 30 A/mm2. Hence investigation on performance such as Torque versus various current density and Torque versus Speed were executed. It is very vital to understand the performance of HEFSM at no load and at load are varied by adding 10% of FEC circumference of cross section area. On top of that, comparison on the performance between new designed model and previous model was also conducted.
