Abstract

"APERFEIçOAMENTOS PARA CONTROLADOR DE MOTOR LINEAR". A presente invenção refere-se a um compressor de gás de pistão livre que apresenta um cilindro, um pistão, o pistão sendo alternadamente movido dentro do cilindro em cursos alternados de compressão e expansão. Um motor elétrico linear de movimento alternado é acionavelmente acoplado ao pistão. Um controlador é programado para controlar ou ajustar a entrada de potência para o motor linear com base em uma relação que inclui pelo menos o presente curso de compressão ou a duração do curso de expansão, a relação sendo indicativa da posição do centro morto superior (TDC) do pistão, incluindo a ausência de qualquer colisão. Na concretização preferida, o controlador obtém uma medição que reflete a diferença entre a duração do curso de compressão e a duração do curso de expansão e ajustar a entrada de potência em resposta à medição obtida.
