Abstract
The invention relates to a dental motor or coupling unit (10, 20), which is designed to be coupled to a dental instrument (100, 105) and comprises an electrical circuit arrangement which is connectable to a supply unit (110, 120) via a conductor pair (91). The circuit arrangement contains: a load (30), which is supplied with DC voltage or a low-frequency AC voltage via the conductor pair (91); a transmitting and receiving unit (40), which is designed to communicate by means of / via near-field communication and, for this purpose, to wirelessly transmit an HF communication signal transmitted via the conductor pair (91) or to couple it into the conductor pair (91); and coupling and separating elements (31, 41), which decouple the DC voltage or low-frequency AC voltage from the HF communication signal.
