What Is The Principle Behind Magnetic Coupling? A Video Explains It All.

If the large rotary crusher were to become jammed during operation, it could potentially result in damage to its motor.  Similarly, in the case of a chemical agitator, its propeller is connected to the motor through a shaft. If the shaft seal were to leaks, the resultant chemical spill could potentially cause significant harm to both personnel and equipment! That’s why the innovative solution of magnetic coupling was developed.

What you see here is a magnetic coupling produced by SDM. It consists of a driving rotor and a driven rotor. These two rotors interact via a magnetic field to achieve non-contact power transmission. It can be likened to an invisible hand that seamlessly transmits power from one shaft to another.

When a crusher is equipped with an axial magnetic coupling, any excessive load on the driven components will result in the cessation of torque transmission . This occurs due to the lack of a physical connection between the rotors, thereby effectively preventing motor overload. In chemical liquid agitators, the radial magnetic coupling isolates the drive and driven components using a sealed isolation cover, entirely eliminating the possibility of chemical leakage.

Compared with traditional mechanical systems, magnetic couplings provide superior transmission performance, substantial energy savings, low-noise and low-vibration operation, as well as broader applicability. If this meets your needs, don’t hesitate to learn more!
