Description

technical field [0001] The invention relates to an axial magnetic field flywheel pulse synchronous generator system, and belongs to the technical field of electric motors and power electronics. Background technique [0002] The flywheel pulse generator is a flywheel energy storage device that utilizes the large inertia of the shaft system to store energy and realizes electromechanical energy conversion by coaxial motor / generator. There are two types of flywheel energy storage devices currently in use or under development: the first is that the power level of energy storage and energy release is equivalent, and one motor can be used to alternately realize the functions of electric and power generation. The small and medium-capacity magnetic levitation flywheel energy storage system is for this The first type has the characteristics of compact structure and high efficiency, and is generally used as a flywheel battery; the second type is that the energy storage power is more th...
