Magnetic Couplings are used in applications where a magnetic force is transmitted without contact between the magnetic coupling and the object requiring the magnetic force. Magnetic force can be transmitted through an airspace or through non-magnetic materials.
Transmission systems can be of various types, although the majority are axial. Magnetic force can vary within a system depending on the polarities of each part of the system. Magnetic force will vary according to the distance between the parts of the system and will be stronger for short distances and less strong the further the parts are moved away from each other.
Systems can be optimized according to customer requirements. Polarities, sizes of magnets and the position of magnetic force transfer can all be varied.
