Study of Magnetics Performance of Inset Permanent Magnet Synchronous Machine (Inset - PMSM) Using Finite Element Method

Abstract

Inset Permanent Magnet synchronous machine (Inset - PMSM) is a specific kind of permanent magnet synchronous machine. The magnetic flux in air gap of electrical machine is one of the important parameters and it imply to the electric or mechanical energy of machine. Using radial pole structure, the characteristics of magnetic field in air gap of an Inset PMSM with 6 poles and 36 slots are simulated. In this paper, we simulated and observed the influence of axial channel rotor core of Inset-PMSM to the value/quantity of magnetic flux in air gap. Magnetic flux quality is also considered in this simulation. The simulations were compared with the conventional rotor structure. The flux density per pole in the air gap was measured with three different angles, 00, 250 and 400.

Influence of edge slotting of magnet pole with fixed slot opening width on the cogging torque in inset permanent magnet synchronous machine

“…The finite element method magnetics tool, FEMM 4.2, and LUA 4.0 scripting language were used to investigate the inset PMSM characteristics based on finite element analysis. [9][10][11] The air gap magnetic flux distribution and cogging torque for the experimental models have been investigated and compared.…”
