In the recent days, possibilities of high-temperature superconductors (HTS) bulk applications such as Machines, MAGLEV, MRI and soon have actively been under discussion in the world. The main purpose of this paper bulk superconducting materials effect in synchronous machines. HTS bulks on the rotor and stator, which can be used to improve the synchronous machine flux link between the rotor and the stator. In addition, superconducting materials, reduces the leakage flux, weight and dimensions, and increases efficiency , torque and reliability.Keywords: high temperature superconductor, HTS bulk, synchronous machines, permanent-magnet (PM
