What Is a DC Solenoid?
A DC solenoid is a device that converts the electrical energy of electromagnetic force into mechanical energy of linear drive by a moving iron core.
A typical solenoid is based on pull-type motion as it retracts the movable iron core. By combining various tip shapes of movable iron cores and drive units, it is possible to realize pulling, pushing, stopping, hitting, bending, and other motions at a low cost. As a result, DC solenoids are used in various applications such as home appliances, ATMs, vending machines, ticket checkers, and automatic doors.
DC Solenoid Applications
DC solenoids are used in various applications because they convert electrical energy into mechanical linear motion, and inexpensively realize various motions such as pulling, pushing, stopping, hitting, and bending, depending on the movable iron core and tip shape.
The main applications include the sorting of hardened coins in vending machines, commonly known as coin mecks, and the sorting and ejection of change.
Principle of DC Solenoids
DC solenoids convert the electrical energy of electromagnetic force into mechanical energy of linear drive by a movable iron core.
Compared to AC solenoids, DC solenoids do not generate inrush current when energized, and are characterized by low operating noise.
DC solenoids are generally composed of a main frame, a coil, a spring, a fixed iron core, and a movable iron core.
The operating principle of a solenoid with these configurations is a pull-type operation, in which a magnetic field is generated as soon as current flows through the coil, and the movable iron core is attracted to the fixed iron core by electromagnetic induction. While the coil is energized, the movable iron core is attracted to the fixed iron core, and when the coil is de-energized, the movable iron core returns due to spring force.
On the other hand, there is also a push type solenoid that has a push bar on the fixed iron core to push out the push bar as soon as the movable iron core is attracted to the fixed iron core.
Difference Between AC and DC Solenoids
AC solenoids generally have higher starting current and pull force than DC solenoids. However, if an AC solenoid is overloaded or locked during movement, a large current will continue to flow, resulting in coil burnout. Therefore, when adopting AC solenoids, safety considerations such as thermal fuse and overcurrent protection must be taken into account in the design.
On the other hand, with DC solenoids, the current itself is very small and the pull force is also small, so the coil will not burn out even if the moving part is overloaded or locked. Therefore, DC solenoids are superior in terms of safety, but their performance itself is inferior to AC solenoids.
