A magnetic coupling is a non-contact coupling that transmits torque between two shafts using magnetic fields instead of physical connections. It consists of two magnetized components: an inner rotor attached to the driving shaft and an outer rotor connected to the driven shaft, separated by a containment barrier. The magnetic forces transfer torque through the barrier, allowing for sealed and leak-free operation. Magnetic couplings are commonly used in applications requiring hermetic sealing, such as pumps in chemical, pharmaceutical, and food processing industries. They are valued for their reliability, reduced maintenance, and ability to eliminate the risk of fluid leakage.
