Either AC servo or DC servo can be added to the lock. What’s the point of adding a lock to a servo motor? Do all servo motors need to hold the brake? Let’s make it simple.
The difference between the servo motor with lock gate and the ordinary servo motor is that the servo motor with lock gate has a lock coil, which will automatically hold the motor if the coil is powered off. The brake motor is generally used on the gravity shaft to prevent the shaft from falling after the power failure. That is to say, not all servomotors need to be designed with a brake, and many servomotors do not integrate relevant functions.
The application of servo lock is that in the case of a sudden power failure, the motor stops running and may be reversed driven by the equipment doing work. An example is to lift a thing vertically with the servo, the power failure, the servo does not turn, lifted to the mid-air equipment due to gravity falls, the servo follows the reverse. At this time, if your motor has a brake structure, it will quickly hold the motor to prevent the fall of the situation. Generally, the lock installed in the motor is not a type of manual release function, but in some special conditions, such as when the equipment needs to manually adjust the position after power failure, if the lock is not opened, the device is locked and cannot be manually adjusted, in this case, the lock needs to have a manual release function. Therefore, when selecting the servo motor, it is necessary to determine whether the lock needs to be added, and whether the lock needs manual release function according to the use of the motor.
