摘要: A fluid compressor has a sealed case, an electric motor section, and a compression section. Both sections are provided in the sealed case, with their axes extending substantially horizontally. The sealed case is filled with lubricant. At the start of the compressor, the rotational speed N of the electric motor section is gradually increased, but maintained at least once at a prescribed value for a predetermined period. At the stop of the compressor, the rotational speed N is gradually decreased, but maintained at least once at a prescribed value for a predetermined period.
