A principle of hybrid magnetic levitation system using permanent magnets (PMs) and high‐temperature superconductors (HTSCs) for a linear‐motor‐type carrier system in a high‐quality clean room and a magnetic bearing for the flywheel energy storage system are discussed. A substantial levitation force was generated by the repulsive force between like poles of coupled magnets. However, the repulsion system with magnets is essentially unstable without control. Thus, HTSCs are applied for control elements of the PM‐HTSC hybrid magnetic levitation system. In this system, the levitation force becomes stronger than in the system without PM, and we can expect sandwich‐type magnetic bearing capable of sustaining greater force.
