What is magnetic motor coupling ?
The magnetic motor coupling transmit the torque without contact through magnetic forces between the internal and external rotor. They ensure hermetic separation between driving and driven side in pumps and agitators sealing hazardous liquids and gases reliably.
The magnetic motor coupling consists of an external and an internal rotor. The external rotor has got high-quality, permanent magnets of changing polarity on the inner side while the internal rotor has got them on the outside.The external rotor is usually fixed on the drive side and the magnets are glued in the keyways. The magnets of the internal rotor on the driven side are fully encapsulated.
How magnetic motor coupling work?
The magnetic motor coupling consists of three parts. The external rotor consists of a series of rare earth magnets that are ground, potted and attached to the inside diameter of a steel hub. The Internal rotor consists of a series of rare earth magnets that are ground, potted and attached to the outside diameter of a steel rotor. The sealing is achieved statically.
Then there is a synchronous operation under a constant torsion angle. If the maximum coupling torque and the maximum torsion angle are exceeded, the power transmission is interrupted.Since the torque transmission of the magnetic motor coupling is interrupted, the motor will be effectively protected.The motor will not burn out due to absolute torque transmission.
Application of magnetic motor coupling
Typical applications: Gear pumps, centrifugal pumps, screw spindle pumps, agitators, PU foaming lines.
