Abstract

ROTOR IMANTÁVEL. É descrito um rotor imantável permanentemente com uma estrutura do rotor central incluindo um eixo do rotor suportando uma culatra cilíndrica. O rotor inclui adicionalmente uma estrutura multipolar compreendendo elementos de polo circunferencialmente alternados, e uma tampa do rotor estendendo-se longitudinalmente sobre a estrutura multipolar. O rotor inclui adicionalmente uma tampa de extremidade incluindo uma superfície de encaixe posicionada em encaixe com uma extremidade da culatra. A tampa de extremidade define primeira e segunda características antirrotação para impedir rotação circunferencial de um ou mais elementos de polo em torno da culatra. A primeira característica antirrotação é configurada diferentemente da segunda característica antirrotação e cada característica antirrotação define uma característica de transmissão de torque para transmitir um torque de diferentes locais na estrutura multipolar.
