Abstract

motor de magneto permanente para bomba elétrica submersível. trata-se de um motor de bomba elétrica submersível (13) que tem seções do rotor (51) montadas ao longo de um comprimento de um eixo (50) para provocar a rotação do eixo. os magnetos de pólo (50) são espaçados um do outro e montados no eixo. cada um dos magnetos de pólo é polarizado com um pólo norte em um de seus lados interno e externo (63, 65) e um pólo sul no outro de seus lados interno e externo. um magneto ortogonal (57) é montado entre cada um dos magnetos de pólo. cada um dos magnetos ortogonais é polarizado com um pólo norte em uma de suas extremidades (67, 69) e um pólo sul na outra de suas extremidades.
