Servo motor usually has the braking function. Generally braking refers to the back end of the servo motor,dc servo motor brake installed in the back end of the motor, working through the brake pad acting on the main shaft of the motor, the dc servo motor brake and hold the motor spindle.
DC servo motor with driver has advantages like low cost, simple structure, large starting torque, wide speed control range, easy control. But it requires regular and simple maintenance.
DC servo motor with 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 dc servo motor brake, otherwise there is no need to brake.
DC servo motor with brake is generally used for vertical or oblique movement occasions, horizontal movement can not use the brake, generally speaking, DC servo motor with brake for motor power off, is not allowed to move after the application. For example, a vertical axis with no self-locking function.
