Device with stator, rotor, and air gap protection device
A recently granted patent (Publication Number: US12003166B2) discloses a device with a stator and a rotor designed to address issues related to eccentric rotation. The device includes an air gap protection device fixedly connected to either the stator or the rotor, with a radial distance maintained between the protection device and the other component. This setup allows the protection device to make contact and rotate relative to the stator or rotor in case of eccentric rotation, effectively reducing the radial distance between the components.
Furthermore, the patent details the composition and structure of the air gap protection device, which includes a body fixedly connected to the stator and rotating structures connected to the body. These rotating structures, made of wear-resistant non-metallic materials like polyurethane or polyether ether ketone, are strategically positioned to maintain a specific radial distance from the rotor. The device also incorporates positioning plates and fixing brackets to ensure stability and proper functioning. Additionally, the patent covers applications of this technology in generators, wind generating sets, and includes features like displacement sensors and alarm systems for monitoring and control purposes.
