Compared with the ordinary motor, the servo motor has an encoder structure, which will move synchronously with the motor rotor, continuously collect the torque, speed and position information of the motor movement, and feed it back to the driver to continuously correct the error.

All kinds of projects that require high control precision will give priority to integrated servo motors.

Of course, the servo is not 100% safe.

Sometimes in some projects involving vertical displacement movement, we will give priority to the servo with brake. Why?

Quite simply, a servo motor with a brake locks the rotor in the event of a power failure, preventing it from continuing to rotate.

If it is a vertical lifting project, if the motor is powered off and does not hold the rotor, the rotor will rotate violently in the opposite direction until the lifted goods fall to the ground, or the length of the lifting rope reaches the limit.

We obviously cannot accept such a result.

On the one hand, it affects the work, and on the other hand, it also damages the motor itself.

Therefore, the motor with a brake came into being.
