For mounting on motors

Incremental hollow shaft encoders are used with drive motors, particularly in the fields of lift construction, crane technology and wind energy.

Drive motors that are controlled directly only work optimally at their nominal speed. In order to generate a suitable level of torque as soon as the motor starts running, special switches are used in the motor (such as the Y- Δ transformation).

Through the use of converters, the torque of a drive can be used more productively as soon as the drive is started up and over a wider speed range.

In order to be able to make use of converters with older motors, an incremental encoder is needed to determine the speed. It can usually be mounted on the shaft behind the motor.

This creates a mechanical connection between the encoder and the motor shaft using a shaft adapter with the appropriate threaded hole. Depending on the design of the encoder, the shaft adapter is connected to the encoder either directly or via a flexible double-loop coupling.Wachendorff’s mounting kits offer you the highest level of flexibility. In addition to an encoder, a set of shaft adapters with the main thread diameters and a ready-to-use connection cable are also included. The mounting kit for the solid shaft encoder also includes a mounting angle and a double-loop coupling.

High disruptive strength – long service life

Incremental hollow shaft encoders are used in drive motors, particularly in the fields of lift construction, crane technology and wind energy.

As a preventive measure, service personnel replace important mechanical and electrical components at cyclical service intervals. One of the plant operators’ most important demands is to keep the service intervals as short as possible.

With its mounting kits, Wachendorff ensures that the incremental encoder WDG100K is made available for service intervals – as well as for unplanned service calls – for various shaft diameters and with the appropriate reduction shells and connection cable.

Since these reduction shells are made of plastic, the degree of protection against shaft current discharges is increased due to its isolating effect.

The appropriate shell is simply clipped into place in the hollow shaft of the WDG100K, meaning that it cannot be lost, and the encoder is fixed to the motor shaft using the clamping ring. The sealing strip provided is braced against the motor’s housing and thus keeps the encoder’s housing securely in place.


For the most important converter manufacturers, Wachendorff will also pre-configure the cable to the appropriate plug on request.
