Abstract

um motor elétrico de cc tendo um estator montado em um substrato, o estator tendo um conjunto de bobina tendo um núcleo magnético, um rotor montado no estator com imãs permanentes distribuídos radialmente em torno do rotor, os imãs permanentes se estendendo além do núcleo magnético, e sensores montados no substrato adjacente aos imãs permanentes. durante operação da passagem de motor dos imãs permanentes através dos sensores produz um sinal substancialmente sinusoidal de tensão variada substancialmente sem ruído e/ou saturação, permitindo uma posição angular do rotor em relação ao substrato a ser determinado a partir de porções lineares do sinal sinusoidal sem requerer o uso de um codificador ou sensores de posição e sem requerer redução de ruídos ou filtragem do sinal.
