Motor-operated compressor

Abstract

The present disclosure provides a motor-operated compressor comprising a compression module configured to compress a fluid by an orbiting motion of a scroll, an inverter module configured to control an operation of the compression module, a driving motor disposed in the compression module and configured to provide a rotational force for the orbiting motion of the scroll, a power element disposed in the inverter module and configured to provide power to the driving motor, and a three-phase airtight terminal comprising columnar conductors and columnar insulators disposed in an alternating manner along concentric circles. The three-phase airtight terminal may be configured to electrically connect the power element and the driving motor.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority under 35 U.S.C. § 119(a) to Korean Patent Application No. 10-2019-0067409, filed on Jun. 7, 2019, the disclosure of which is incorporated by reference herein in its entirety.BACKGROUND1. Technical Field

[0002] The present disclosure relates to a motor-operated compressor operated by a motor.2. Description of the Related Art

[0003] Compressors are classified into a mechanical type using an engine as an operating source and a motor-operated type using a motor as an operating source.

[0004] For a motor-operated compressor, a scroll compression method suitable for a high compression ratio operation is widely known. A motor part is installed inside a sealed casing of the motor-operated compressor having a scroll compression method (hereinafter, abbreviated to motor-operated compressor). And a compression part including a fixed scroll and an orbiting scroll is installed on one side of the motor part. The...
