Embodiment Construction

[0064]In particular embodiments, the disclosed flywheel assembly includes an exterior and an interior. The flywheel exhibits desirable strength properties, as well as controlled failure and the ability to tune the permanently magnetized internal field in the event of fatigue. Advantageously, the magnetized interior includes magnetized particles configured to prevent heat build-up caused by eddy currents when rotating. This allows rotation in the vacuum range for efficiency, since heat dissipation is not critical, and a simpler control scheme for storing and recovering energy in the flywheel system.

[0065] figure 1 A flywheel arrangement 10 is shown. This assembly is discussed in conjunction with pending fellow British Patent GB1312927.5, the contents of which are hereby incorporated, so that the described flywheel assembly 10 is described relatively simply by the following:

[0066] The flywheel assembly 10 includes rotor assemblies 12 , 14 having an outer ring rotor 12 a...

Abstract

An annular rotor for a flywheel, the rotor comprising a traction having a fiber matrix around a shaft and arranged in layers, the layers including spaces between adjacent traction windings, wherein the shaft's The winding angle between the normal and the puller is less than 3.5°, and the matrix also includes magnetic particles whose size is smaller than the critical crack size of the puller.

Description

technical field [0001] The present invention relates to flywheel assemblies and, more particularly, to an improved method and system for determining the magnetic field properties of a rotating portion of a flywheel assembly. Background technique [0002] A flywheel is a well known device for storing energy in a rotating mass. The amount of energy stored in the flywheel is proportional to the square of the rotational speed. Generally, the rotational speed is increased by transferring energy to the flywheel for storage by applying torque to the flywheel. Conversely, energy can be released or recovered from the flywheel by applying a torque to the load, which causes the flywheel to spin less rapidly. [0003] Many known flywheel power energy storage assemblies include electric machines, which can function as motors or generators. When the electric machine is used as a motor (ie: when the flywheel assembly is in "start" or "recovery" mode), the electrical energy supplied to t...
