Servo motor brake, also known as holding brake, is a component of power release. Generally, the servo motor with brake is integrated with the motor. Generally, DC24 V power supply is used.

It is mainly used to lock the rotor shaft of servo motor after power off.

It is generally used on the vertical servo axis to prevent sudden power off. Due to the gravity effect, the vertical load will drive the motor to rotate and slide down, resulting in danger.
