Abstract

"MéTODO DE CONTROLE DE OPERAçãO DE COMPRESSOR DE MOVIMENTO ALTERNADO". Trata-se de um método de controle de operação de um compressor de movimento alternado que é revelado no qual, no caso em que um motor está sobrecarregado, uma freq³ência de operação é aumentada para produzir fluxos magnéticos de um magneto e de uma corrente de entrada que são mutuamente deslocados, de modo que um compressor de movimento alternado pode ser acionado de forma estável mesmo no caso de sobrecarga. Para este propósito, enquanto o compressor de movimento alternado utilizando um inversor é operado em uma freq³ência regulada, uma carga de corrente do motor é medida e a carga medida é comparada com uma carga de referência preestabelecida. Quando da comparação, se a carga medIda for maior do que a carga de referência, é determinado uma sobrecarga e a freq³ência de operação é aumentada tanto quanto um certo valor maior do que uma freq³encia de oscilação, para executar uma operação em sobrecarga. De modo a compensar uma redução do curso gerada a medida que a freq³ência de operação é aumentada por tanto quanto um certo valor, a voltagem aplicada para o motor 6 aumentada por tanto quanto um certo valor de acordo com a freq³ência de operação aumentada, desse modo executando uma operação em sobrecarga.
