Abstract

"MOTOR DE CORRENTE CONTìNUA SEM ESCOVAS COM ìMã CHANFRADO". A presente invenção refere-se a um motor CC sem escovas com uma configuração de ímãs aperfeiçoada presos a um seu rotor. O motor de corrente contínua sem escovas inclui um estator que tem bobinas para induzir um fluxo magnético de acordo com a corrente elétrica aplicada, e um rotor instalado dentro do estator, e que inclui um núcleo no qual um eixo giratório está conectado, e ímãs presos ao redor do núcleo. Cada um dos ímãs tem porções chanfradas nos lados dos respectivos ímãs.
