Abstract

"DISPOSITIVO PARA ALIVIAR CARGA DE EMPUXO EM UM SISTEMA DE ROLAMENTO DE ROTOR USANDO IMãS PERMANENTES". A presente invenção proporciona um dispositivo e um método para intensificar a capacidade de carga de empuxo em um sistema de rolamento de rotor. O dispositivo de intensificação de carga compreende um estator e um rotor dispostos de tal maneira que se obtenha uma intensificação de capacidade magnética de carga de empuxo através do emprego de um número de ímãs permanentes, o que produz uma força de atração ou uma força de expulsão entre o rotor e o estator.
