Abstract

um atuador eletromecânico (?ema?) é provido de trajetos de carga redundante para acionar o curso do atuador. o ema inclui um parafuso rotativo, uma porca encaixada no parafuso e com uma superfície dentada externa, e um membro estriado rotativo com uma superfície estriada que engata a superfície dentada externa da porca. uma haste do atuador é acoplada à porca para movimento linear com a porca. um primeiro motor é operável para rotar o parafuso em relação à porca para fazer com que a porca se desloque linearmente ao longo do parafuso, e um segundo motor é operável para rotar o membro estriado e a porca, de modo que a porca se desloque linearmente ao longo do parafuso. consequentemente, a haste do atuador se move linearmente por operação do primeiro motor sozinho, por operação do segundo motor sozinho, e por operação simultânea do primeiro e do segundo motores. um dispositivo de retenção pode ser incorporado em cada trajeto de carga.
