Abstract
The arrangement has a motor (16) which has an electronic commutator and during operation is supplied from alternating current (AC) mains (L, N) via a rectifier (52) connected thereto, and a direct current (DC) link (22, 58) connected to said rectifier (52) and having a DC voltage (U.sub.ZK) of greater than 100 V. The motor has an arrangement (25, 27) fed from said alternating current mains (L, N) via a transformer (24) and for supplying electronic components (14, 20, 26) of the motor with a DC voltage, and a user interface (12) provided for transmission of data to or from the motor (16). Said user interface, with which a current supply (24b) electrically isolated from the motor (16) is associated, electrically isolated from the motor (16).
