Abstract

"MOTOR ELéTRICO ROTATIVO TENDO UMA PLURALIDADE DE PóLOS DE ESTATOR E/OU PóLOS DE ROTOR DESLOCADOS". A presente invenção refere-se a um motor elétrico rotativo que tem um estator com uma pluralidade de conjuntos espaçados axialmente de estator correspondente (3, 6) e elementos de rotor (22, 23, 24). O estator de cada conjunto é um anel com pólos posicionados circunferencialmente em torno de um eixo de rotação. O rotor de cada conjunto tem uma pluralidade de ímãs permanentes dispostos circunferencialmente ao longo de um entre-ferro anular oposto aos pólos de estator. Os ímãs permanentes de conjuntos de elementos de rotor adjacentes e/ou os pólos de conjuntos de estator adjacentes são deslocados um do outro na direção axial para cancelar os efeitos de torque de engrenamento produzidos por cada um dos conjuntos."ROTARY ELECTRIC MOTOR HAVING A PLURALITY OF STATOR POLES AND / OR OFFSET ROTOR POLES". The present invention relates to a rotary electric motor having a stator with a plurality of axially spaced assemblies of corresponding stator (3, 6) and rotor elements (22, 23, 24). The stator of each set is a ring with poles positioned circumferentially around an axis of rotation. The rotor of each assembly has a plurality of permanent magnets circumferentially disposed along an annular gap opposite the stator poles. Permanent magnets of adjacent rotor element assemblies and / or adjacent stator assembly poles are offset from each other in the axial direction to cancel the gear torque effects produced by each of the assemblies.
