Backgrounds: As rotating machines become more complex and their operation accuracy improves, limitations imposed on unbalanced vibration of the rotor are becoming stricter. The traditional approach to unbalanced vibration is offline dynamic balancing, which is very costly. Purposes: In this paper, we design and propose an electromechanical automatic balancing system based on a rigid single rotor with a single plane and constant rotational speed. The system includes actuators, vibration counting equipment, and control algorithms, and it can monitor and balance rotor unbalance vibration in real time while the equipment is operating. Compared to other balancing actuator types, the proposed design has a larger counterweight and improved electromagnetic compatibility; as such, it can provide the stepless counterweight adjustment. Methods: Through the independent design and construction of electromechanical balancing head actuator as well as the developed supporting drive control algorithm and super balancing capability processing algorithm, fast and accurate identification and target suppression of rotor vibration is achieved, and the control algorithm is programmed using a programmable logic controller (PLC), which effectively removes the dependence on computer equipment. Results: Simulation and experimental validation of the algorithm have shown that the electromechanical automatic balancing actuator has a vibration reduction capability of 18um at 600 rpm for the propeller single rotor system. Conclusions: The electro-mechanical automatic balancing head can achieve a larger proportion of counterweight and a greater balancing capacity with the same total weight. In addition, the automatic balancing system has better electromagnetic compatibility, realizes stepless adjustment of counterweight mass, and the control algorithm makes the unbalanced vibration of the rotor in the balancing process continuously monotonically decrease, which ensures the efficient and precise stability of the balancing process.
