phần ứng
Definition
- Noun:
- Armature: The rotating or stationary part of an electric machine (such as a motor or generator) that carries alternating current and is influenced by the magnetic field of the field windings to produce voltage or torque.
- Rotor (in some contexts): In certain types of electrical machines, the "phần ứng" can refer specifically to the rotating component.
Usage Examples
- Noun:
- Phần ứng của máy phát điện bị hư hỏng. (The generator's armature is damaged.)
- Cần kiểm tra cuộn dây phần ứng. (It is necessary to check the armature winding.)
- Phần ứng quay tạo ra dòng điện. (The rotating armature generates an electric current.)
Advanced Usage
- In precise technical contexts, "phần ứng" is distinguished from the "phần cảm" (the field system or stator that produces the main magnetic field). The interaction between these two parts is fundamental to the operation of electric machines.
Variants and Related Words
- Lõi phần ứng (n): Armature core. The laminated iron core of the armature that holds the windings and reduces eddy current losses.
- Cuộn dây phần ứng (n): Armature winding. The set of insulated coils wound around the armature core.
- Dòng điện phần ứng (n): Armature current. The current flowing through the armature windings.
Synonyms
- Armature: The standard and most precise equivalent term in electrical engineering.
- Rotor: A synonym only when the armature is the rotating part of the machine (common in DC motors and generators).
Related Technical Terms
- Phần cảm (n): The field system. The part of the machine (usually with field windings or permanent magnets) that establishes the main magnetic field.
- Máy điện (n): Electrical machine. A general term for devices like generators and motors where "phần ứng" is a key component.
- Cảm ứng (n): Induction. The process by which a voltage is induced in the "phần ứng".
