Abstract

"COMPRESSOR ELéTRICO E MéTODO DE CONTROLE PARA O MESMO". Quando um compressor elétrico é ativado, dados de corrente inicial são selecionados por um seletor, e um motor é acionado com o torque correspondendo aos dados da corrente inicial. Quando o motor é acionado por 1/2 volta, o seletor seleciona os dados da diferença de corrente. Os dados da diferença de corrente correspondem a uma velocidade instruída. Depois da alternação do seletor, o motor é acionado para girar na velocidade instruída.
