  • Magnetic couplers are devices that can transmit torque between rotating shafts without any physical contact. They use magnetic fields to transfer power from one shaft to another, providing a smart and permanent solution to issues that can arise from seal failure or damage to the coupling in machines such as chemical mixers or crushers. This article will provide an in-depth understanding of how magnetic couplers work, using FEA simulation by EMworks.A magnetic coupler is composed of two parts: a primary rotor and a secondary rotor. These rotors are separated by an air gap, ensuring there is no physical contact between them. There are different types of magnetic couplers, such as the axial type and the radial type.In the axial type magnetic coupler, the magnet arrangement is synchronous. When the drive shaft, connected to a motor, is rotated, the poles of the magnets on the primary and secondary rotors begin to overlap. This overlap creates a push-pull effect, resulting in a force that generates torque on the output shaft. This torque drives the system, providing a reliable and robust seal without the risk of leakage.Similarly, in the radial type magnetic coupler, the rotors are mounted on the input and output shafts of the system. As the drive shaft rotates, the magnets on the rotors create a push-pull effect, generating torque to drive the output shaft. This type of magnetic coupler can be effectively used in applications such as chemical mixers, where the mixing propeller is connected to the motor via a shaft.In addition to offering a reliable and leak-free solution, magnetic couplers also ensure worker safety by preventing chemical leaks that could harm both the worker and the machine. By isolating the driving and driven parts, magnetic couplers provide a smart and permanent solution to the issues that can arise from seal failure or coupling damage. They are an innovative and effective technology that ensures efficient and safe operation in various industrial applications.
  • Subtitles section
  • Please have a look at this chemical mixer.
  • The propeller of the mixer is connected with the motor via a shaft.
  • This shaft is supposed to have a reliable and robust seal.
  • However, what if the seal fails?
  • Here's another scenario.
  • A big rotary crusher, which suddenly gets stuck.
  • Yes, you're right.
  • The coupling in the motor can get damaged.
  • Similarly, in the mixture, the chemical leaks out and can harm the worker as well as the machine.
  • Does the engineer in you have a smart and permanent solution to this issue?
  • We have a device called a magnetic coupler.
  • The magnetic coupler can transmit torque between rotating shafts without any physical contact.
  • It uses magnetic fields to transfer the power from one shaft to another.
  • The coupler consists of two parts, a primary rotor and a secondary rotor.
  • These rotors are separated by an air gap.
  • In this video, we'll see the details of the workings of magnetic couplers with the help of FEA simulation by EMworks.
  • A magnetic coupler consists of two separate magnet assembly rotors.
  • This magnet arrangement is called a synchronous magnetic coupler, and this is an axial type magnetic coupler.
  • Here is an example of a radial type magnetic coupler.
  • These rotors are mounted on the input and output shafts of the system.
  • When we rotate the drive shaft using a motor, the poles of the magnet begin to overlap each other, causing a push-pull effect.
  • The resulting force creates torque, which drives the output shaft.
  • Let's use this radial magnetic coupler in the mixer.
  • Yes, we've solved the problem.
  • Here, the driving and driven parts are isolated from each other, so there's no leakage issue in the system.
  • Let's now use an axial magnetic coupler in a crusher.
  • Here again, both rotors are isolated.
  • If the load on the driven component is large, the two parts will move out of the synchronism and cease transmission of torque.
  • This prevents damage of the crusher and deformation of the shaft.
  • The motor is also saved from overloading here.
  • The synchronous magnetic couplers are used in compressors and water pumps, as these equipment require constant speed to maintain the desired flow rate.
  • The main disadvantage of the synchronous coupler is that if the load is working at slip speed, it may lead to decoupling.
  • To overcome this problem, eddy current based magnetic couplers are used.
  • The eddy current coupler has a similar rotor arrangement as that of the axial synchronous coupler.
  • The only difference is that the magnets of the output shaft are replaced with a copper disc.
  • When the input shaft rotates, the magnetic field of the permanent magnet rotates along with it.
  • This induces an electric current in the output copper disc.
  • Here is the result of transient electromagnetic simulation done in EMWorks software.
  • The eddy current formation is illustrated here.
  • Here, the yellow spot areas are equivalent to the formation of magnetic poles.
  • This magnetic pole interacts with the input magnet assembly and creates torque in the output shaft.
  • The magnitude of the resultant torque can be adjusted by just changing the air gap distance between the rotors.
  • If we increase the air gap distance, then the torque will be affected.
  • As this coupling provides soft start and speed regulation, it's used in roller conveyors.
  • The magnetic couplers have several advantages and limitations, which are listed here.
