Abstract
The present specification discloses a compressor characterized in that a nonpolar solvent is used as a working fluid and an insulation part of a rotating section is formed from a low dielectric constant plastic film having a specific dielectric constant of 1.2 to 3.0. This compressor has been reduced in leakage current and improved in safety and reliability, and therefore can realize energy savings for devices such as a refrigerant system device.
Claims8
A method for producing a rotator of a compressor which uses a nonpolar refrigerant as a working fluid comprising the steps of:
- preparing a low dielectric constant plastic film having a specific dielectric constant of 1.2 to 3.0;
- and
- forming an insulation part with said plastic film in a slot of an iron core included in said rotator.
