Stainless steel permanent magnet couplings have no wearing parts, providing wear-free transmission of torque between the driving and the driven parts through any non-ferrous wall. This makes them suitable for mixers and agitators in the food processing and pharmaceutical industries where contents must be isolated from the drive.
Permanent magnet couplings use multi-pole, high-energy, powerful magnets assembled around an outer core to drive a magnetic inner core. This allows transfer of torque through a solid wall. They also offer the benefit of slipping when the maximum torque is exceeded, thus protecting mechanical components in the drive line from damage.
