定义
The core plunger is a cylindrical ferromagnetic component that moves axially within a drive coil assembly when energized by electrical current. It serves as the moving element in solenoid actuators, electromagnetic valves, and linear motion systems, translating electromagnetic force into precise mechanical displacement. Its design ensures minimal friction, consistent magnetic coupling, and reliable operation in industrial automation applications.
工作原理
When electrical current flows through the drive coil, it generates a magnetic field that attracts or repels the ferromagnetic core plunger, causing linear motion. The plunger's movement is proportional to the current magnitude and coil design, enabling controlled actuation in mechanical systems.
