Description

technical field [0001] The invention relates to an external rotor flywheel pulse synchronous generator system, which belongs to the technical field of motors and power electronics. Background technique [0002] The flywheel pulse generator is a flywheel energy storage device that uses the large inertia of the shaft system to store energy, and coaxial motor / generator to realize electromechanical energy conversion. There are two types of flywheel energy storage devices currently in use or under development: the first type is that the power levels of energy storage and energy release are equivalent, and one motor can be used to alternately realize the functions of electric power generation 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 ...
