Definition
  1. Noun:
    • Commutator (in electrical engineering): A component in a direct current (DC) generator or motor that collects the current generated in the armature windings and converts alternating current (AC) to direct current (DC) for the external circuit. It is a cylindrical assembly of conductive segments insulated from each other.
    • Collector (general electrical term): A device or terminal for collecting electrical current from a moving part, such as in a generator.
Usage Examples
  • Noun:
    • Bộ phận này là góp điện của máy phát. (This part is the commutator of the generator.)
    • Các lá đồng trên góp điện cần được làm sạch định kỳ. (The copper segments on the commutator need to be cleaned regularly.)
    • Dòng điện xoay chiều được chỉnh lưu thành một chiều nhờ góp điện. (The alternating current is rectified into direct current by the commutator.)
Advanced Usage
  • Technical Context: The term "góp điện" is almost exclusively used in technical, engineering, and educational contexts related to electrical machinery. It is not used in everyday conversation.
  • Function Clarification: It is often explained in relation to its function: "bộ phận góp điện" (the current-collecting part) or "vành góp điện" (the commutator ring).
Variants and Related Words
  • Cổ góp (Commutator): A more technical synonym, literally "collecting neck."
  • Vành góp (Commutator ring): Refers specifically to the ring-like structure.
  • Bộ chỉnh lưu (Rectifier): A broader term for any device that converts AC to DC, which includes but is not limited to a mechanical commutator.
  • Roto (Rotor): The rotating part of a machine, which often contains the commutator.
Synonyms
  • Commutator: The most precise and common technical equivalent in English.
  • Collector: A more general term; "collector ring" can be used for slip rings in AC machines, which are different from commutators.
Related Phrases (Technical Terminology)
  • Lá góp điện (Commutator segment/bar): The individual copper bars that make up the commutator.
  • Chổi than góp điện (Commutator brush): The carbon brush that makes contact with the commutator to collect current.
  • Hư hỏng góp điện (Commutator fault/failure): A malfunction of the commutator.
