A magnetic coupling is a contactless coupling that uses magnetism to transmit torque and provide isolation between the motor and the driven equipment. The magnetic coupling consists of an outer rotor, an inner rotor and an isolation end cover. The outer rotor is connected to the driving motor, and the inner rotor is connected to driven equipment such as pumps and mixers. When the motor rotates, the magnetic field generated by the permanent magnets on the outer rotor transfers torque to the inner rotor, thereby driving the loading equipment to rotate. The key advantage is that it is leakproof and suitable for transporting flammable and toxic fluids. Widely used in chemical, pharmaceutical, food and other industries.
