- Abstract
- In this paper, we assessed the characteristics of the rotational energy loss by drag force according to a size change of the new amorphous stator core used on PMSM/G. The accurate method for measuring rotational energy was presented through the spin down test using superconductor flywheel energy storage system (SFES). The mathematical model for core loss of amorphous was constructed using the radial and tangential components of magnetic flux density through the experimental data analysis for the cores of PMSM/G. Rotational losses in the cores of PMSM/G were more influenced by radial component than by tangential component of magnetic flux density. Experimental results and proposed mathematical model of core loss using radial component and tangential component of magnetic flux density were in good agreement. Also it was confirmed that use of the new amorphous stator core on PMSM/G core could considerably improve the energy storage efficiency of the SFES.
