Conveyor clutches for cleanroom applications

11 May 2009

Misumi Europa has expanded its rollers & conveyor components product group to include magnetic clutches in two designs. The components enable non-contact, low-wear, magnetic power transmission to transport devices, for example in clean room applications.

The TM magnetic drives (magnetic clutches) provide non-contact power transmission via a magnetic field. Conveyors in clean room applications, such as those used in transporting glass panes for flat screens, require transport devices that create as little dust build-up as possible. Thanks to the TM magnetic drive, the components do not come into contact, thereby eliminating associated wear and contamination. The drives offer quiet operation.

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. The number of magnetic clutches required for the application is calculated from the size and scale of the torque to be transferred, which depends on the workpieces.
