技术定义与适配语境
典型 线圈 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

A coil is an electrical conductor wound into a series of loops or turns, designed to generate a magnetic field when an electric current passes through it. In industrial applications, such as trip solenoids, it serves as the core electromagnetic actuator that produces linear or rotary motion by attracting or repelling a ferromagnetic plunger or armature, enabling mechanical switching or control functions in machinery.

定义
A coil is an electrical conductor wound into a series of loops or turns, designed to generate a magnetic field when an electric current passes through it. In industrial applications, such as trip solenoids, it serves as the core electromagnetic actuator that produces linear or rotary motion by attracting or repelling a ferromagnetic plunger or armature, enabling mechanical switching or control functions in machinery.
工作原理
The coil operates on the principle of electromagnetism: when an electric current flows through the coiled conductor, it generates a magnetic field proportional to the current and number of turns. This magnetic field interacts with a movable ferromagnetic core (e.g., in a trip solenoid), creating a force that moves the core to perform work, such as tripping a mechanism or actuating a valve.
材料
Typically made from copper or aluminum wire with enamel or polymer insulationwound around a bobbin of thermoplastic (e.g.nylonPBT) or thermoset material. The core may include ferromagnetic materials like iron or steel for enhanced magnetic flux.

Wire Gauge
AWG 18-30
Insulation Class
Class B (130°C) or higher
Operating Voltage
12-240 V DC/AC
Temperature Range
-40°C to 150°C
标准
