Recently, Inner permanent magnet (IPM) synchronous machines have been introduced as a possible traction motor in hybrid electric vehicle (HEV) and traction applications due to their unique merits. In order to achieve maximum torque per ampere (MTPA), optimization of the motor geometry parameters is necessary. This paper Presents a design method to achieve minimum volume, MTPA and minimum ...

Rare-earth magnets which are the best solutions for PMSM rotors are expensive which makes that other types of motors are used in the applications. The solution of the replacement of these motors with PMSynRM that use low-cost type of ferrite magnets becomes more tempting lately. This paper proposes two different types of low-cost ferrite solutions: first a V permanent magnet assisted synchronou...

This paper deals with characteristics of interior permanent magnet synchronous motor considering anisotropic characteristics of electrical steel sheets. Motor characteristics of back electro-motive force (EMF), d-q axis inductances, and core loss are calculated by FEA considering anisotropy of electrical steel sheets and compared to the results from experiment and general FEA; using single mate...

One maintenance task that still exist with conventional motors, are bearing lubrication and renewal. Bearingless motors are replaced with conventional motor that uses a magnetic levitation force to suspend a rotor without any mechanical contact. In bearingless motors, additional windings are wound together with motor windings in stator slots. In this paper, a bearingless permanent magnet-type s...
