Abstract

OPERAçãO SEM SENSOR DE UM MOTOR DE CORRENTE CONTìNUA COMUTADO ELETRONICAMENTE. A presente invenção refere-se a um processo e a uma unidade de acionamento elétrica com um motor de corrente contínua (11) comutado eletronicamente, um inversor (12) e um aparelho de controle (16) para a operação sem sensor do motor (11), no qual são determinadas as passagens zero da tensão induzida na fase respectivamente sem corrente pelo campo de rotação do rotor, sendo que as passagens zero ocorridas são detectadas; o momento da passagem zero seguinte da tensão induzida pelo campo de rotação do rotor é calculado previamente e um intervalo de tempo (At) depois do momento previamente calculado ao menos da última passagem zero detectada é avaliado.SENSOR-FREE OPERATION OF AN ELECTRONICLY CHANGED CURRENT MOTOR. The present invention relates to a method and an electric drive unit with an electronically switched DC motor (11), an inverter (12) and a control apparatus (16) for sensorless operation of the motor (11). ), in which the zero-passages of the phase-induced voltage respectively without current are determined by the rotor field of rotation, and the zero-passages that occur are detected; the moment of the next zero pass of the rotor rotating field induced voltage is calculated previously and a time interval (At) after the previously calculated moment of at least the last detected zero pass is evaluated.
