Braking Device
Since ball screws do not have a self-locking function, especially when installed vertically, a brake device must be set to prevent the load from sliding down. Common brake devices include
- Electromagnetic brakes
Electromagnetic brakes apply braking force through electromagnetic force, usually automatically when the motor stops, ensuring that the screw remains in the current position.
- One-way overrunning clutch
The one-way overrunning clutch allows the screw to rotate freely in one direction and locks in the opposite direction to prevent the screw from reversing.
