Basic Design and Operation Structure Examples of installation & Application
When power is on, the coil will be energized to exert the magnetism and pull the armature plate down to compress springs. Meanwhile, the friction disc in the brake will be disengaged then shaft can move.
When power is off, magnetism in the coil will disappear and the armature plate will be rebounded by springs. At the same time, the friction disc in the brake will be engaged to hold the shaft.
