Hollow bore motors are a special class of electric motor that have hollow shafts and are also known as hollow shaft and/or through shaft motors. The center portion of the motor is a hole completely through the center axis of the motor which allows various items such as cables, hoses, piping or even lasers to pass through without obstruction. A servo hollow bore motor has all the performance and benefits of classic shaft style servo motors but are mechanically different with the hollow bore.
