Electromagnetic brake in electric actuator
Thread Content
I have a question: I possess an electric actuator equipped with an electromagnetic brake that applies braking when powered and releases when the power is cut off. Over time, due to wear and tear, the distance between the brake components increases; does this result in a decrease in torque? Additionally, I would like to know why the brake pads break
After wear, the gap increases, friction decreases, and the braking torque decreases. It can be adjusted.
The brake pads have worn thin and lack strength.
The torque of the electromagnetic brake in electric actuators does not change; only the gap between the brake wheel and the brake pads increases. Therefore, after a power outage, due to inertia, the stopping time is longer than that of a newly installed actuator. If the thickness of the brake pads is within the acceptable range, adjusting their clearance using the clearance adjustment screw is sufficient to meet the stopping time requirements. If the brake pads do not meet the requirements, they can be replaced. Different gaps between several sets of brake pads, as well as poor quality of the brake pads, are all causes of their breaking.
