Why use a magnetic coupling?
The most important advantage of a magnetic coupling is that it allows the transmission of torque through a barrier without the use of rotating seals, along with the associated problems of leakage, potential contamination and continual maintenance.
How does a magnetic coupling work?
In the simplest terms, magnetic couplings work using the fundamental concept that opposite magnetic poles attract. The attraction of the magnets transmits torque from one magnetized hub to another (from the driving member of the coupling to the driven member). Torque describes the force that rotates an object.
How does a MagnaDrive work?
How does the MagnaDrive technology work? In a typical ASD application, the ASD is installed between a motor and the load the motor is driving, generally a pump, fan or blower. Relative motion between the magnets and the copper creates a magnetic field that transmits torque from motor side to load side.
What happens when the magnetic coupling is actuated?
Engagement. When the clutch is actuated, current flows through the electromagnet producing a magnetic field. The rotor portion of the clutch becomes magnetized and sets up a magnetic loop that attracts the armature. The armature is pulled against the rotor and a frictional force is generated at contact.

How are magnetic couplings used in a pump?
Magnetic Couplings. Magnetic couplings offer a non-contact transfer of torque. They are typically used in magnetic drive pumps and magnetic mixers for seal-less applications; keeping corrosive, toxic, or flammable liquids from escaping into the atmosphere. By driving one magnetic hub, torque is transmitted magnetically to the other magnetic hub.
When does maximum torque of magnetic coupler occur?
For instance, for a particular Torque Coupler, the maximum torque may not be achieved until the system has rotated through 15°. This may or may not be an issue for some applications, but it must be observed that maximum Torque and maximum Linear Force occur at the maximum system skew.
How does the backing plate of a magnetic coupler work?
The backing-plate connects the non-working faces of the magnet and increased the effective filed in the gap and therefore the coupling force.
