Abstract
PURPOSE: To provide a safe electric door apparatus which ensures automatic slow closure in case of power failure, by means of a drive motor having a field system formed by an armature and a permanent magnet and a means adapted to cause the armature to be shortcircuited through a resistance against a power failure.
CONSTITUTION: When the power supply (positive and negative) is fails, contactor coils C, O and H are deenergized. Consequently, any of contacts C5, O5 and H3 is closed and an armatuae A is short circuited through a resistance PR2 in a circuit of A-H3-O5- C5-PR2-A. The resistance PR2 is set at a lower level than that at deceleration, at deceleration, while the N and S arrangement of a permanent magnet provides a constant field system. A motor 6 generates a strong power generation torque. The torque reduces to zero when the door is braked but it increases in proportion to the speed of the door when it falls by the own weight. This ckecks the closing speed of the door from increasing beyond a given speed, ensuring a safe closure
