Electric actuator assembly for actuating e.g. garage door, has three electric actuators, each with DC motor and AC/DC converter that has power circuit and control circuit with selector for adjusting output voltage of converter

摘要

The assembly has three electric actuators of different power, supplied by an AC main supply to actuate a door (2). Each actuator has an AC/DC converter (3a) and a DC motor (4). The motors provide the same nominal current and different nominal voltages. Each converter has a power circuit with a transistor (5), a rectifier (7) and a capacitor (8), and a control circuit (6) with a selector (9) for adjusting its output voltage. An independent claim is also included for a method of manufacturing an assembly of electric actuators used for actuating closing, hiding or solar protection units.
