  • Load generating unit for testing actuator and load simulator for testing actuator
    Patent number: 12000754
    Abstract: The present invention provides a load generating unit for testing an actuator, the unit including a first permanent magnet and a second permanent magnet spaced apart from each other; a third permanent magnet or a ferromagnetic body arranged in a row with the first permanent magnet and the second permanent magnet between the first permanent magnet and the second permanent magnet; and a first link passing through central axes of the first permanent magnet and the second permanent magnet to be penetrated to a central axis of the third permanent magnet and be connected to the actuator, wherein the third permanent magnet and the link are displaced in a length direction of the first link by a magnetic force. According to the present invention, the complexity, cost, and inertia of a device may be overcome and a load profile may be easily generated.
