The WDG 100I series from Wachendorff Automation was specifically designed for drive motors applications (like e.g. elevator construction, crane technology and wind energy). Particularly the design and the dimensions of the bearings ensure reliability and a long service life.
The encoder is mounted directly on the motor shaft. The precision-balanced clamping ring of the encoder ensures the vibration-free operation of the encoder on the motor shaft. Apart from mechanical vibrations, so-called shaft currents can also affect the bearings and electronics of the encoder through the motor shaft. This can result in a gradual failure of the encoder mechanism - in particular the bearings - and impair the digital signals. A tailor-made, pre-assembled insulating sleeve protects the encoder against these shaft currents. The insulating sleeve is available in different diameters. It can be fitted quickly and easily.
The matching shapes of the sleeve and the shaft as well as an integrated lock nut prevent them from accidentally falling out. Nevertheless it is possible to dismantlethe insulating sleeve and replace it in order to fit a different shaft diameter.
