Description

Technical Field

[0002] A coil generally refers to a wire winding in a ring shape. The most common coil applications include: motors, inductors, transformers, and loop antennas, etc. A coil in a circuit refers to an inductor. It means that wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow or can contain an iron core or a magnetic powder core, which is simply called an inductor. Inductors can be further divided into fixed inductors and variable inductors. A fixed inductor coil is simply called an inductor or a coil. It is represented by L, and the units are henry (H), millihenry (mH), and microhenry (uH). 1H = 10^3mH = 10^6uH. Currently, stator coils are generally wound with round copper wires covered. After the round copper wires covered are processed, they need to be ground to ensure the smoothness of the surface of the round copper wires covered and avoid the surface of the round copper wires covered being too rough, which affects the quality of the stator.
