Description

Technical Field

[0001] The utility model relates to the technical field of flywheel energy storage, in particular to a guide device for assembling a motor rotor and a motor stator for flywheel energy storage. Background Art

[0002] The flywheel energy storage system is an energy storage device that converts electromechanical energy and uses physical methods to achieve energy storage; through the electric / generating reciprocal bidirectional motor, the electrical energy and the mechanical kinetic energy of the high-speed rotating flywheel are converted and stored, and through frequency modulation, rectification, constant voltage and different types of load interfaces.

[0003] When storing energy, the electric energy is converted by the power converter to drive the motor, and the motor drives the flywheel to accelerate. The flywheel stores the energy in the form of kinetic energy, completing the energy storage process of converting electric energy into mechanical energy. The energy is stored in the high-speed rotating flywheel body. After that, the motor maintains a constant speed until it receives a control signal for energy release. When releasing energy, the high-speed rotating flywheel drags the motor to generate electricity, and the power converter outputs current and voltage suitable for the load, completing the energy release process of converting mechanical energy into electric energy. The entire flywheel energy storage system realizes the input, storage and output process of electric energy.

[0004] In order to obtain a storage flywheel with smooth operation and stable performance and to solve the problem of rotor dynamics, flywheel units generally adopt a vertical structure, that is, the motor rotor and the motor stator are installed vertically, and the air gap between the motor rotor and the motor stator is generally about 0.5-2mm. Due to the large mass and long length of the motor rotor and the unstable operation, when the motor rotor passes through the motor stator during the assembly process, it is very easy to cause the rotor end face to collide or even cut off part of the motor stator potting glue due to shaking, thereby causing the motor stator insulation to be damaged and cannot be used.
