A flywheel energy storage mixed type superconducting magnetic bearing is composed of a stainless steel spindle (1), a radial electromagnetic bearing stator (2), a low-temperature Dewar (3), a superconducting bearing permanent magnetic rotor (4), a superconducting bearing block stator (5), a superconducting bearing coiling stator (6), a superconducting bearing iron magnetic suction force disk rotor(7), a flywheel (8)m a radial electromagnetic bearing iron magnetic ring rotor (9) and a superconducting bearing iron core magnetic yoke (10). The superconducting bearing block stator (5) and the superconducting bearing coiling stator (6) are arranged inside the low-temperature Dewar (3) and installed on the stainless steel spindle (1) in a sleeving mode, and liquid nitrogen or a refrigeration machine is used for cooling. The superconducting bearing coiling stator (6) is arranged below or around the superconducting bearing block stator (5). The radial electromagnetic bearing stator (2) is installed on the upper portion of the stainless steel spindle (1) in a sleeving mode. The superconducting bearing iron magnetic suction force disk rotor (7) is installed outside the low-temperature Dewar(3) and installed on the stainless steel spindle (1) in a sleeving mode.
