Easy mounting on all motor shafts

Incremental encoders are used, among other things, on frequency-controlled drive motors, especially in the elevator construction, crane technology and wind energy industries.
Drive motors that are directly controlled only operate optimally at their rated speed. In order to generate a suitable torque already at start-up, special circuits are used in the motor (e.g. star-delta). By using converters, the torque of a drive can be better utilized already during start-up and over a wider speed range.
So that older motors can also be operated on an inverter, an incremental encoder is required to determine the speed. This can usually be attached to the shaft behind the motor. For this purpose, the mechanical connection between the encoder and the motor shaft is established by means of a shaft adapter with a corresponding threaded hole in solid shaft and hollow shaft encoders. Depending on the encoder version, the shaft adapter is connected via a flexible double loop coupling or directly to the encoder.
Wachendorff attachment kits offer the user maximum flexibility. This is because, in addition to the encoder, these kits contain a set of shaft adapters with the most important thread diameters as well as a preassembled connection cable. The mounting kit with full shaft encoder also includes a mounting bracket and a double loop coupling.
When using hollow shaft encoders (direct mounting on the shaft), a set of reducing sleeves is supplied for different shaft diameters. Since these reducing bushings are made of plastic, the insulating properties simultaneously increase protection against shaft currents. The corresponding sleeve is simply snapped captively into the hollow shaft of the WDG100K encoder and the encoder is fixed to the motor shaft via the clamping ring.
Through these sets, service and modernization teams always have the right material on board.
