Abstract
a presente invenção refere-se a um sistema e um método de impulsão de motor para controlar um motor elétrico. o sistema de impulsão de motor inclui uma pluralidade de linhas de fase conectadas de maneira comutável ao motor elétrico, uma pluralidade de interruptores controláveis, e um controlador. o controlador é acoplado de maneira comunicativa à pluralidade de interruptores controláveis e configurado para receber um sinal indicativo de uma velocidade do rotor e uma posição do rotor do sensor do rotor. o controlador gera um valor que expressa uma força contraeletromotriz (contra-fem) como uma função da posição do rotor com respeito a um quadro de rotação de referência. com base na posição do rotor, o controlador determina uma pluralidade de correntes de fase que reduzem uma ondulação residual de torque do motor elétrico até aproximadamente igual a zero. o controlador aciona os interruptores controláveis para alimentar o motor elétrico com a pluralidade de correntes de fase.
