Abstract

Patente de Invenção: <B>"PROCESSO PARA MEDIçãO DO NúMERO DE ROTAçõES DE UMA MáQUINA DE INDUçãO"<D>. Para medição do número de rotações(n) de uma máquina de indução (2), cujo estator está ligado através de um regulador de corrente alternada (4) controlável a uma rede de tensão alternada (L1, L2, L3) de uma ou mais fases, de acordo com a invenção, o estator é separado da rede de tensão alternada (L1, L2, L3) por pelo menos um período (<30>t) predeterminado, por abertura das válvulas (6) do regulador de corrente alternada (4), sendo que, nesse momento (<30>t), é medida pelo menos uma tensão de estator (u~ SX~, u~ SY~) induzida pelo movimento de rotação do rotor. Dos valores de medição obtidos desse modo, é determinada a freq³ência dessa tensão de estator (u~ SX~, u~ SY~) e, da mesma, é derivado o número de rotações (n) da máquina de indução (2).
