servo motor with the brake is to protect the motor when the motor stops, the servo motor can not be subjected to the axial force when the motor is not powered, because the external force causes the motor operation and affect the system with the brake, otherwise there is no need to brake.
The function of the servo motor brake is equivalent to the hand brake of the car. So the servo motor brake is used to lock the position when the motor stops, not to move the motor due to external force.
Servo motor with brake is generally used for vertical or oblique movement occasions, horizontal movement can not use the brake, generally speaking, servo motor with brake for motor power off, is not allowed to move after the application.
In general, the servo motor with the brake is more expensive than the price without the brake, whether the brake is not directly related to the power of the motor, so the motor with the brake is more expensive than the motor without the brake motor.
There are many applications for servo motors. As long as it is necessary to have a power source, and to the fine Degree of requirements may generally involve the servo motor. Such as: machine tools, printing equipment, package Installation equipment, textile equipment, laser processing equipment, robot, automatic production line and so on Precision precision, processing efficiency and working reliability.
