How does a magnetic coupling work?
Today we are going to give a very basic overview on magnetic coupling.
Starting with the basics, we know we all know about the attraction of magnets. this attraction is possible without the magnets being in contact and if we move on the other will follow. Using this principle if we then mount a series of magnets on a simple shaft arrangement. wetherefore have the basis of a non-contacting coupling.
Working principle
A magnetic coupling is a coupling that transfers torque from one shaft to another, but using a magnetic field rather than a physical mechanical connection. In another words, The magnetic coupling works by using the power generated by permanent magnets. No external power supply is needed. These are permanent magnets not electro magnets.
The magnets are installed alternating between poles in a side by side and opposing position as seen in the diagram. The main body of each coupling half is of ferromagnetic material to aid the channelling of the magnetic field correctly and therefore maximizing transmittable torque.
