The design method of initial topology of interior permanent magnet synchronous machine (IPMSM) for hybrid electric vehicle (HEV) propulsion is described in this paper. Design constraints are selected on the basis of limitations imposed by machine's manufacturer and application (e.g. maximum copper slot fill factor, air gap length, permanent magnet material, limited space available in drive trains,...
This paper details a qualitative comparison between different types of electrical machine for hybrid electric vehicle traction applications. Targets set by the US Department of Energy for the year 2020 are used as goals. Several types of machine for this application will be discussed, focusing on the benefits and challenges of each machine when applied to these targets. Then the machines are compared...
This paper presents a comparison of two inlet permanent magnet synchronous machines with concentrated windings. A novel 24-teeth/28-poles machine design with flux barriers in the stator teeth is compared to a common 30-teeth/20-poles design, which is widely used for hybrid electric vehicle (HEV) applications. Detailed comparison of important machine characteristics such as torque ripple, iron losses,...
In this paper, an entirely novel embranchment of variable flux permanent magnet (PM) machine-switched-flux memory machine (SFMM) is proposed and implemented as integrated-starter-generator (ISG) highly desirable for hybrid electric vehicles (HEVs). The flexible flux controllability of air-gap flux is achieved due to the magnetic susceptibility of AlNiCo PM, where the magnetization levels can be tuned...
This paper presents an energy-based model of a series hybrid electric vehicle. The proposed propulsion system has a new configuration using a wound-rotor synchronous generator (WRSM) and a doubly-fed induction machine (DFIM). From the classic dq dynamical equations of the WRSM and DFIM the port-controlled Hamiltonian models of each machine is described. One of the abilities of the port-based models...
Flux-switching permanent magnet (FSPM) motor is a relatively novel brushless machine having magnets and concentrated windings in the stator instead of the conventional rotor-PM topology, which exhibits inherently sinusoidal PM flux-linkage, back-EMF waveforms and high torque capability. However, since the airgap field is produced by the stator-magnets alone, it is difficult to be regulated. Hence,...
