Abstract :
The value of critical current (Ic) in High Temperature Superconductor (HTS) tape is greatly influenced by perpendicular magnetic flux density B⊥. Therefore, Ic of HTS magnet is determined by not only operating temperature but also the B⊥. In this paper, flux distribution and operating current are calculated according to the field coil change in 100 hp class HTS motor. The magnetic flux density of field coil is calculated by changing the outer radius and inner width of field coil. Biot-Savart equation is used as analytic method for the characteristic analysis of magnet. 3D FEA (Three Dimensional Finite Element Analysis) is used for the magnetic field distribution in the HTS motor. The operating current of 100 hp class HTS motor is calculated by using Ic-B⊥ curve.
