Misumi drives transmit power via magnetic field

A Misumi product story
Edited by the Engineeringtalk editorial team May 13, 2009

Misumi Europa has introduced two magnetic clutches that enable non-contact, low-wear, magnetic power transmission to transport devices, for example, in cleanroom applications.

The TM magnetic drives (magnetic clutches) provide non-contact power transmission via a magnetic field.

Conveyors in cleanroom applications, such as those used in transporting glass panes for flat screens, require transport devices that create as little dust build-up as possible.

With the TM magnetic drive, the components do not come into contact, thereby eliminating any associated wear and contamination.

The drives are also characterised by quiet operation.

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 conveyer device or the conveyed goods.

There are two designs available according to the direction of power transmission.

The 90deg 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.

The number of components, the size of the clutch and the relevant torque are therefore interdependent.

Subsequently, users are able to select the appropriate component from the table in the catalogue.

A complete list of all the TM magnetic drives with full specifications is included in the updated issue of the main catalogue 'Mechanical Standard Components for Factory Automation', which came out at the start of April.
