The permanent magnet lifter is a remarkable piece of equipment that has found extensive use in various industries due to its unique working principle and advantageous features. This innovative lifting tool operates on the basis of Faraday’s electromagnetic induction principle, while making use of high-performance permanent magnetic material neodymium borax to achieve its powerful lifting capabilities.
At the core of the permanent magnet lifter‘s working principle is the utilization of neodymium borax, a highly potent permanent magnetic material. Neodymium borax is known for its exceptional magnetic properties, capable of generating a strong suction force within the magnetic circuit. This material is carefully integrated into the interior of the lifter to create a magnetic field that can interact with ferromagnetic materials, such as iron, to achieve lifting.
The process begins with the lifter in its resting state. At this point, the magnetic field lines are in a particular configuration that does not exert a significant lifting force. However, when the handle of the lifter is flipped, a crucial transformation occurs. This action causes a change in the magnetic field lines, activating the lifter and bringing it into a working state. In this state, the lifter is able to generate a powerful magnetic attraction that can firmly hold and lift ferromagnetic workpieces.
The ability to switch between working and closed states by simply flipping the handle is a significant advantage of the permanent magnet lifter. This allows for easy control and operation, enabling users to quickly engage or disengage the lifting force as needed. Moreover, since the lifter does not require an external power supply to function, it offers several benefits. It is a safe option as there is no risk of electrical hazards, making it suitable for use in environments where electrical safety is a concern. Additionally, it is energy-efficient, as it does not consume electricity during operation, reducing operating costs and environmental impact.
When the permanent magnet lifter is in working condition, the suction lifting surface at the bottom of the lifter plays a crucial role. This surface forms a pair of longitudinal magnetic poles, which create a strong magnetic field that reaches out to attract ferromagnetic workpieces. The magnetic force is so powerful that it can firmly hold iron material workpieces, ensuring a secure grip during lifting operations.
The design of the bottom surface of the lifter also includes a V-shaped groove. This feature adds to the versatility of the lifter as it enables it to not only lift plate-shaped workpieces but also cylindrical workpieces. The V-shaped groove provides a stable and secure hold for cylindrical objects, preventing them from rolling or slipping during lifting. However, it should be noted that the lifter has strict requirements on the thickness and area of the plate. The thickness and area of the plate directly affect the strength of the magnetic attraction. If the plate is too thin or has a small area, the magnetic force may not be sufficient to hold it securely. On the other hand, if the plate is too thick or has a large area, it may exceed the lifting capacity of the lifter.
For example, in a manufacturing plant, the permanent magnet lifter can be used to lift heavy steel plates. The operator flips the handle to activate the lifter, and the magnetic field generated by the neodymium borax material immediately grabs onto the steel plate. The longitudinal magnetic poles on the bottom surface ensure a firm hold, allowing the plate to be safely lifted and transported to another location. If a cylindrical workpiece needs to be lifted, the V-shaped groove comes into play, providing a stable grip and enabling the cylindrical object to be lifted with ease.
In conclusion, the working principle of the permanent magnet lifter is based on Faraday’s electromagnetic induction principle and the use of high-performance neodymium borax material. By flipping the handle, the lifter can be switched between working and closed states, providing a safe, energy-efficient, and highly efficient lifting solution. The suction lifting surface and V-shaped groove on the bottom of the lifter enable it to handle a variety of workpieces, while the strict requirements on plate thickness and area ensure proper operation and safety. With its unique features and advantages, the permanent magnet lifter has become an essential tool in many industries.
