The TM magnetic drives (magnetic clutches) provide non-contact power transmission via a magnetic field. With the TM magnetic drive, the components do not come into contact, thereby eliminating to the greatest possible extent any associated wear and contamination. The components are suitable for potential semi-permanent use within the permissible scope of application on the basis of the permanent magnetic specification. This makes it possible to construct power-limited conveyor devices that can be operated continuously without causing damage to the conveyor device or the conveyed goods. There are two designs available according to the direction of power transmission: The 90° variant transfers the power via two TM magnetic drives arranged at right angles to each other, while in the parallel variant, the two drives are located parallel to each other and function in opposing directions.
