The drive device has a low voltage motor (1) and a switching power supply. The switching power supply has a transformer (5), a primary full-wave rectifier (7) and a switching device (9) arranged between the full-wave rectifier and the transformer. The primary correcting variable is changed depending on a secondary measured variable. An independent claim is also included for a method for driving net curtain with the drive device. |
