Driven magnet assembly is the rotating component in magnetic couplings that transfers torque without physical contact through magnetic fields.
The driven magnet assembly is a critical component in magnetic coupling systems, consisting of permanent magnets arranged in a specific pattern and mounted on a rotor. It operates without mechanical contact with the driving magnet assembly, creating a hermetic seal barrier while transmitting torque through magnetic flux. This assembly is typically housed in a non-magnetic containment shell and rotates in response to the magnetic field generated by the driving magnet assembly, enabling torque transmission across sealed barriers in pumps, mixers, and other industrial equipment.

The primary advantage is contactless torque transmission, which eliminates mechanical wear, prevents leakage in sealed systems, and requires no lubrication, making it ideal for hazardous or sterile environments.
High temperatures can cause permanent magnet demagnetization, particularly with NdFeB magnets above 80°C. SmCo magnets offer better temperature stability up to 350°C but are more expensive. Proper thermal management is critical for maintaining torque capacity.
Minimal maintenance is needed due to the contactless design. Primary concerns are monitoring bearing wear in supporting structures, checking for corrosion on containment shells, and verifying magnetic strength degradation over time through periodic torque testing.
