Abstract :
The operating characteristic of Moving Coil-Type LOA (MC-LOA) is changed by the construction of magnetic circuits and load conditions. This paper deals with single-pole type, single-sided multipole, and double-sided multipole according to permanent magnet arrangement. As load conditions, both constant load and variable are used in modeling. To investigate the operating characteristics for load conditions, characteristic analysis has been applied to these conditions. The Characteristic analysis is performed by two-dimensional (2-D) finite element analysis (FEA) batch process based on moving model node technique.
