The invention belongs to the technical field of magnetic levitation energy storage equipment, and particularly relates to a magnetic levitation flywheel energy storage device. The magnetic levitationflywheel energy storage device comprises a shell, a flywheel rotor, a magnetic bearing and a stator and a rotor of a motor, an upper protection assembly, a lower protection assembly, and a driver. Theupper protection assembly comprises an upper protection bearing and an upper conical part, and the inner surface of the upper conical part is provided with a cylindrical surface and a conical surface. The lower protection assembly comprises a lower protection bearing and a lower conical part, and the inner surface of the lower conical part is provided with a cylindrical surface and a conical surface. The driver is electrically connected with a power supply structure of the magnetic suspension flywheel energy storage device. When power is off or the flywheel rotor is out of control, the driverdrives the upper conical part to move to a second position, and the conical surfaces at the two ends of a mandrel abut against the conical surfaces of the upper conical part and the lower conical part respectively. Under the condition that power is off or the flywheel rotor is out of control, the driver drives the upper conical part to move from a first position to the second position, and the conical surfaces of the upper conical part and the lower conical part respectively abut against the conical surfaces at the two ends of the mandrel in an attached mode, so that the flywheel rotor is centered again, and off-axis rotation is not generated.
Description
technical field [0001] The application belongs to the technical field of magnetic levitation energy storage equipment, and in particular relates to a magnetic levitation flywheel energy storage device. Background technique [0002] The maglev flywheel energy storage system is a device that stores electrical energy as kinetic energy and generates electrical energy from the stored kinetic energy. The magnetic levitation flywheel energy storage system has a wide range of applications. It can be applied to mobile platforms such as automobiles and aerospace neighborhoods, and can also be applied to fixed platforms such as power storage of UPS power solar and wind power generation systems. [0003] In the magnetic levitation energy storage system, there is a gap between the rotor and the protective bearing. During the working process of the magnetic suspension bearing, the rotor has been rotating at high speed in the gap. If the rotor can rotate in the center all the time, the m...
