  • Elevator systems are equipped with a governor and an emergency stop device to constantly monitor the ascending and descending speed of the car and bring the car to an emergency stop if it becomes overspeeding to a certain extent.
  • the car and the governor are connected by a governor rope, and when an overspeeding state is detected, the governor restrains the governor rope, activating the emergency stop device on the car side and bringing the car to an emergency stop.

  • the electric actuator has a moving piece (movable iron core) that is mechanically connected to the drive shaft, and an electromagnet that attracts the moving piece.
  • the drive shaft is biased by a drive spring, but under normal circumstances, the electromagnet is energized and the moving piece is attracted, so the movement of the drive shaft is restricted by the electric actuator.
  • the electromagnet In the event of an emergency, the electromagnet is demagnetized, releasing the drive shaft, and the drive shaft is driven by the force of the drive spring. This activates the emergency stop device and brings the car to an emergency stop.
  • the electromagnet When returning the emergency stop device to its normal state, the electromagnet is energized, and then the electromagnet is moved closer to the moving element that moved in the emergency, causing the moving element to be attracted to the electromagnet. Furthermore, with the moving element attracted to the electromagnet, the electromagnet is driven to return the moving element and electromagnet to their normal standby positions.
  • the movable element and the movable element operating part that includes an electromagnet and operates the movable element, which constitute the electric actuator, are attached separately to predetermined parts. Therefore, unless the movable element and the movable element operating part are properly aligned, the electric actuator will not operate reliably, making it difficult to ensure the reliability of the emergency stop device.
