モータ式自動扉。 A linear motor type in which the primary stator of the linear motor is attached to a non-moving object such as a lintel, and the secondary movable element of the linear motor is attached to the top of the door, and the door is opened and closed by the thrust generated between the two. In the automatic door, a secondary side mover 5 of a long plate-shaped linear motor is attached to the upper end of the door 1 along the opening/closing direction thereof, and a secondary movable element 5 of a linear motor is disposed above the door 1 so as to be movable up and down. A support plate 9 , a primary stator 6 of the linear motor attached to the center of the lower surface of the support plate 9 and facing the secondary movable element 5 across a gap, and a peripheral portion of the lower surface of the support plate 9 . A plurality of permanent magnets 11 attached with magnetic poles oriented in the vertical direction
, an electromagnet 8 supported by a non-moving body such as a lintel, and disposed below each of the permanent magnets 11 with magnetic poles oriented in the vertical direction; and a voltage regulator 18 capable of adjusting the voltage of the electromagnet 8. and a gap sensor 14 that is attached to the primary stator 6 and measures the gap between the primary stator 6 and the secondary movable element 5.
When the air gap measured by the gap sensor 14 is less than a preset appropriate air gap value, the voltage is increased, and when the air gap exceeds the preset appropriate air gap value, the voltage is decreased. and a controller 15 for controlling the voltage regulator 18.
