Abstract: A stator structure includes a main body having multiple frames each having an arc panel, a main tooth, at least one secondary tooth, at least one main coil and at least one secondary coil. The main tooth and the secondary tooth are disposed at one face of the arc panel. The main coil is installed at the main tooth, and the secondary coil is installed at the secondary coil. A rotor is penetrated through the stator structure. The frames are in a multi-layer circular arrangement at the rotor, and a dislocation angle exists between the frame at any layer and the frame at the neighboring layer.

Abstract: The disclosure relates to a flywheel energy storage system including a casing, shaft, flywheel, and electric motor assembly. The casing has an inner vacuum chamber, at least one outer accommodating slot and at least one separator which separates the inner vacuum chamber from the at least one outer accommodating slot. The shaft is rotatably disposed in the inner vacuum chamber. The flywheel is located in the inner vacuum chamber and fixed to the shaft. The electric motor assembly includes a first motor rotor and a motor stator. The motor stator is accommodated in the at least one outer accommodating slot and fixed to the at least one separator. The first motor rotor is fixed on the shaft and located between the shaft and the motor stator. Part of the at least one separator located between the first motor rotor and the motor stator includes magnetically permeable material.

Abstract: A rotor of an electric motor including a rotor core, two conductive end plates, a plurality of conductors and a casting metal is provided. The rotor core has a central hole and a plurality of slots surrounding the central hole at a predetermined interval. The two conductive end plates, disposed at two ends of the rotor core, have a plurality of fixing structures, respectively. A plurality of cavities is disposed between two neighboring fixing structures and the shape and the positions of the cavities correspond to that of the slots. The conductors are shaped as long bars and penetrate the slots. Two ends of the conductors are fixed by the fixing structures. The casting metal is injected into the cavities and the slots, and further covers the peripheral of the conductors and the fixing structures, two ends of the rotor core and outside of the two conductive end plates.
