Hermetically sealed compressor

摘要

A hermetically sealed compressor in which the occurrence of heat generation and insulation breakdown is reduced at the connection portion between a lead wire of a motor and an external terminal is configured as follows. The compressor main body and the motor are integrally structured. The flow path of a fluid to be compressed is in fluid communication with the internal space of the motor. The stator of the motor is formed by winding each of a plurality of independent coils in multiple turns. Each of the coils is provided with a separate external terminal.
