Embodiment Construction

[0025] A straight line can be regarded as a circular ring with an infinite radius, so the running track of the linear motor can be designed as a closed-loop linear motor connected end to end. The moving side of the linear motor is the kinetic energy carrier. When storing energy, the linear motor acts as a motor to generate electromagnetic thrust and convert the electrical energy into kinetic energy of the moving side of the linear motor. When releasing energy, the primary of the linear motor acts as an alternator winding and interacts with the secondary to convert the kinetic energy of the moving side into electrical energy for output.

[0026] The main form of linear motor kinetic energy storage method:

[0027] a. Continuous moving side kinetic energy carrier, discontinuous fixed side linear motor coil winding length (long moving side secondary, short fixed side primary);

[0028] b. Continuous fixed side, discontinuous moving side linear motor coil winding kinetic energy ...

Abstract

The invention provides a linear motor moving side ring kinetic energy storage and transportation gravitational potential energy storage method and relates to the field of linear motor application. During the energy storage process, by means of a linear motor, the electric energy is converted into the kinetic energy of the moving side of the linear motor to be stored, or the kinetic energy of the moving side of the linear motor is converted into the gravitational potential energy to be stored through the transportation process. During the energy release process, the moving side of the linear motor moves relative to the stationary side of the linear motor, so that the kinetic energy / the gravitational potential energy is converted into the electric energy to be outputted based on the electromagnetic induction principle. In this way, the cycle process of energy storage, energy deposit and energy release is realized.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to the application of linear motors to physical energy storage. Background technique [0002] Energy storage technology will be a key core technology for the development of the future power grid and new energy industry, which is related to the long-term interests of the country and energy security. Therefore, developed countries have successively upgraded the energy storage industry to a national strategy. The development of new energy is an important strategic measure to cope with climate and environmental changes, ensure energy security and sustainable economic and social development, and is also the core of the "third industrial revolution". New energy represented by wind power and solar power is intermittent, volatile and random, and its large-scale consumption has become a worldwide problem. In 2012, my country's wind power abandoned wind power amounted to 20 billion kWh...
