Magnetic coupling is a coupling that transmits torque from one shaft, but it uses a magnetic field rather than a physical mechanical connection.
Magnetic couplings are often used in hydraulic pump and propeller systems because a static physical barrier can be placed between the two shafts to separate the fluid from the air operated by the motor. Magnetic couplings do not allow the use of shaft seals, which will eventually wear out and align with system maintenance, because they allow greater off-shaft error between the motor and the driven shaft
1.The Material
Magnet: neodymium magnet
Isolation sleeve: austenitic stainless steel, such as SS304, SS316. There are also industrial plastics, titanium alloys, copper sleeves or ceramics, etc.
Main parts: 20 # steel, martensitic stainless steel
2.The advantages
Magnetic couplings are used for standard applications.
Good sealing.
There is no contact with the torque transfer element.
No maintenance.
High efficiency optional.
