rotor coil
Definition
Noun: - The rotating armature of a motor or generator: A "rotor coil" is the set of windings or conductive loops that are mounted on the rotating part (the rotor) of an electric motor or generator. When electric current flows through this coil, it interacts with a magnetic field to produce torque (in a motor) or generate electricity (in a generator).
Usage
The term "rotor coil" specifically refers to the conductive winding component of the rotor assembly. - The technician replaced the damaged rotor coil in the electric motor. - In a generator, the rotor coil spins within a magnetic field to induce an electrical current.
Advanced Usage
- Technical Specification: In engineering contexts, the design and number of turns in the rotor coil are critical for determining the machine's performance characteristics, such as its speed and torque.
- Failure Analysis: A common point of failure in electric machines is insulation breakdown within the rotor coil, leading to a short circuit.
Variants and Related Words
- Rotor: The general term for the rotating assembly of a motor or generator, of which the rotor coil is a part.
- Armature: A more general term often used synonymously with rotor, especially in DC machines, which includes the coil and its core.
- Stator Coil: The stationary set of windings that interacts with the rotor coil.
- Field Winding: A type of coil, often on the rotor, that generates the main magnetic field in some machine designs.
Synonyms
- Rotor Winding
- Armature Coil (when referring specifically to the rotor's winding in many DC and AC machines)
Related Phrases
- Rotor coil resistance: A key electrical parameter measured during maintenance.
- Rotor coil insulation: The protective material that prevents short circuits between the coil's wires.
Noun
-
the rotating armature of a motor or generator
