Description

Technical field [0001] The invention belongs to the field of motors, and relates to a flywheel pulse synchronous generator structure. Background technique [0002] The flywheel pulse generator is a kind of flywheel energy storage device that uses the large inertia of the shaft to store energy, and the coaxial motor / generator realizes electromechanical energy conversion. 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 electric and power generation functions. Small and medium-capacity magnetic levitation flywheel energy storage systems are 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 than an order of magnitude smaller than the energy release power, and the ele...
