摘要

A drive system (11) for roller shutters is assembled from a permanently excited DC motor and a power supply circuit containing a half bridge current transformer. A winding shaft (1) carries bearing necks (2) on its ends. Roller shutter steel cladding (4) fastens on the winding shaft with an edge and consists of single plates running parallel to each other. The edge opening out from the winding shaft forms an under-edge.
