How to Select Magnets for Magnetic Coupling?
How to Select Magnets for Magnetic Coupling? A magnetic coupling is comprised of two components: a driver and a follower. The driver is the portion of the mechanism that is connected to the prime mover (motor). Through magnetic interaction, the follower reacts to the motion of the driver, resulting in a non-contact transmission of mechanical
