Abstract

DISPOSITIVO COM ESTATOR E ROTOR, E CONJUNTO DE GERAÇÃO DE VENTO. É revelado um dispositivo com um estator e um rotor, em que o dispositivo compreende: um estator (200); um rotor (300), em que um vão de ar é fornecido entre o rotor e o estator (200); e um dispositivo de proteção de vão de ar (100) conectado fixamente ao estator (200), em que a distância radial entre o dispositivo de proteção de vão de ar (100) e o rotor (300) é menor que a distância radial entre o estator (200) e o rotor (300), e o dispositivo de proteção de vão de ar (100) gira em relação ao rotor (300) quando em contato com o rotor (300). Através da disposição do dispositivo de proteção de vão de ar (100) conectado fixamente ao estator (200), o dispositivo de proteção de vão de ar pode girar em relação ao rotor (300) quando em contato com o rotor (300), e a distância radial entre o dispositivo de proteção de vão de ar (100) e o rotor (300) é menor que a distância radial entre o estator (200) e o rotor (300), de modo que, no processo de rotação relativa do estator (200) e do rotor (300), se a distância radial entre o estator (200) e o rotor (300) for reduzida, pode ser garantido que o dispositivo de proteção de vão de ar (100) está em contato com o rotor (300) primeiramente, em vez de permitir que o estator (200) esteja em contato com o rotor (300), a ocorrência de varredura de câmara é impedida e é garantido que o dispositivo com o estator (200) e o rotor (300) não é danificado.
