High Speed Permanent Magnet Assisted Synchronous Reluctance Machines – Part I: A General Design Approach

Design and Rotor Geometry Analysis of Permanent Magnet–assisted Synchronous Reluctance Machines Using Ferrite Magnet

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

Comprehensive Design Procedure and Manufacturing of Permanent Magnet Assisted Synchronous Reluctance Motor

Combining the main advantages of the permanent magnet synchronous motors and pure synchronous reluctance motors (SynRM), permanent magnet assisted synchronous reluctance motor (PMaSynRM) has been considered as a promising alternative to the conventional induction motors. In this paper, utilizing a macroscopic design parameter, called insulation ratio along the q-axis, and based on the magnetic ...

Design of a Permanent-Magnet Assisted Synchronous Reluctance Machine for a Plug-In Hybrid Electric Vehicle

In this thesis, a permanent-magnet assisted synchronous reluctance machine (PMSynRel) design is presented for a plug-in hybrid electric vehicle application. Apart from operating as a traction machine to propel the vehicle, the machine is also used when the vehicle’s battery is charged from the grid. This additional functionality puts restraints (that are discussed in the thesis) on the final ma...

Multi-criteria based design approach of multiphase permanent magnet low speed synchronous machines

This paper presents a design methodology dedicated to multiphase Permanent Magnet Synchronous Machines (PMSM) supplied by Pulse Width Modulation Voltage Source Inverters (PWM VSI). Firstly opportunities for increasing torque density using the harmonics are considered. The specific constraints due to the PWM supply of multiphase machines are also taken into account during the design phase. All t...
