Large Flat Pot NeodymiumMagnet Features:
1.Strong magnetic force
2.Ni or Zn coated surface to avoid corrosion
3.Can be used in water environment
Material: Housing steel and Magnetic core sintered neodymium disc magnet.
Version: Housing, galvanized. Magnet, Ni coated or Zn coated
Note: Shallow flat pot magnets without threaded bush. These magnets are pressed or glued into the receiving holes.
Hairline cracks in the magnetic material are unavoidable for technical reasons in the D=75 version. They do not impair the attracting function of the magnets in any way. large flat pot magnet
Temperature range: max. 80°C.
The basic principle of the holding or pot magnet is to direct and concentrate the flux from both magnetic poles to one active face. This is usually achieved with steel pole pieces or a steel-backing cup. The standard selection can be broken down into three material types and there is a great variety of systems available. The following data should act as a simple guide:
Rare Earth Samarium & Neodymium, pots and assemblies can offer up to eleven times the performance of a Ferrite system in a comparable size. Applications tend to be specialized engineering projects where performance and available space are key factors. Maximum operating temperatures are +60°C for the Neodymium and +150°C – +250°C for the Samarium depending on the design configuration.
Magnetic pot, also called cup magnets or disc magnets, consist of a magnet encased in metal, with its active magnet face exposed. Magnetic pots may have a hole, thread or screw in the center. The metal encasing on a magnetic pot allows the opposing fields of the magnet to transfer back to its active face. This increases the intensity of the magnet’s pull strength to three to four times that of a standard magnet of the same size.
