What are electromagnetic holding electromagnets?
Electromagnetic holding electromagnets, commonly called electromagnetic suction cups, are electromagnetic devices that work like a giant magnet that can be turned on and off freely. This happens because this type of device does not have a plunger and its magnetic circuit remains constantly open. Holding electromagnets are essential in many industrial processes, as they harness the power of magnetism to hold and move metal objects in a precise and controlled manner. Suction cups are designed to be easy to install and offer durability and longevity in use.
How do they work?
The heart of an electromagnetic holding electromagnet is a copper coil. When electric current is applied to this coil, it generates an electromagnetic field. This magnetic field attracts any ferromagnetic object (such as iron or steel) that is nearby. As the coil is energized and the more iron or magnetic elements the part to be held has, the magnetic field intensifies, creating a suction force that holds the object firmly in place. When the current is interrupted, the magnetic field collapses and the object is released.
Where are electromagnetic holding electromagnets used?
Holding electromagnets are a basic element for various industrial processes, thanks to the fact that they take advantage of the force of magnetism to hold and move metal objects in a precise and controlled manner. Some of their most common applications are:
Industrial automation: they are fundamental parts in automated systems, where safe and fast control of parts is required.
Robotics: these suction cups are integrated into robotic arms to perform assembly and handling tasks.
Clamping systems: suction cups are used to hold parts in place during machining or welding processes.
Transport of metal parts: In production lines, for example, electromagnetic suction cups are used to lift, transport and position metal parts of different shapes and sizes.
