Clean in an instant Encoder This newly developed cleaning machine rapidly and fully automatically cleans and maintains sports floors. The WDGA CANopen absolute encoders from Wachendorff with EnDra® multiturn technology ensure that the machine remains on the right path in the hall. Cleaning sports halls is an important issue - especially if sports are being played in which the floors are polluted by certain substances. In handball, adhesive agents with a resin or wax basis regularly allow players to grip the ball better. However, these adhesive agents leave dangerous, dull stains on the floor...

tion of rotation and speeds. Instead, these parameters are determined by an energy wire that operates according to the Wiegand wire principle. The absolute position per revolution (single turn) is measured with four hall sensors and a magnet on the rotating shaft. When the magnetic field moves along the Wiegand wire due to the rotation of the shaft, the soft magnetic core attempts to follow the field, but is prevented from doing so by the hard magnetic sleeve. A constantly increasing field difference exists in the wire - comparable to tensioning a bow. As soon as the external field reaches the...

Image 6 How the machine works. Dirt is removed and a protective film, which ensures optimal sliding friction, is left behind. Image 4 The Bodenwart cleans a path 240 centimetres wide, completing the wet cleaning of an entire sports hall in 15 minutes. Image 7 The Bodenwart works much more quickly and effectively than what can be achieved by manual cleaning.
