Description

technical field [0001] The invention belongs to the field of motors. 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, coaxial motor and generator to realize electromechanical energy conversion; there are two types of flywheel energy storage devices that are currently in use or are being developed: the first The second 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 of this type, which has the characteristics of compact structure and high efficiency, and is generally used as a flywheel battery; The second is that the energy storage power is more than an order of magnitude smaller than the energy release power, and the two motors realize the el...
