Abstract

Un motor que comprende: un estator (210) que tiene un orificio pasante; una pluralidad de secciones de rotor (221) posicionadas rotativamente de manera coaxial dentro del orificio del estator; y un vástago (230), en donde cada una de las secciones de rotor se asegura al vástago; en donde cada sección de rotor de la pluralidad de secciones de rotor incluye uno o más imanes permanentes (610) y tiene polos magnéticos correspondientes; caracterizado porque: cada sección de rotor tiene un primer y segundo chaveteros orientados hacia adentro (660, 670); cuando cada sección de rotor se posiciona en una primera orientación axial y una primera orientación circunferencial, el primer y segundo chaveteros orientados hacia adentro se posicionan idénticamente en cada sección de rotor; el primer y segundo chaveteros orientados hacia adentro se configuran para permitir que cada sección de rotor se posicione en una de al menos tres orientaciones circunferenciales distintas con respecto a una chaveta del vástago.
