This approach has the significant advantage of being able to apply the counterweights without stopping the equipment and has been increasingly used in the industrial field, such as for high-precision machine tools for civilian use, grinders, and military turboprop automatic balancing systems. An automatic balancing system changes the position of the counterweights on a given plane in real time to form the compensation vector. Dynamic balancing of the rotor system is usually achieved by starting and stopping the device and applying test weights and counterweights. Many balancing procedures have been developed to suppress this imbalance-induced vibration. More than 70% of the vibration failures of rotating machinery are caused by the imbalance-induced vibration of the rotor system. The proposed control system can work without computers or high-speed data acquisition equipment, which improves the stability and flexibility of the control system, facilitates the design of the automatic balancing system, and shows excellent potential for industrial applications. The error is less than 1/80 which means that it does not exceed one step in the 80-position-balancer at 1200 rpm. A propeller automatic balancing simulation test bench is used to verify the effect of the method by obtaining the positions of the counterweights and synthesizing the compensation vector in the working mode. In this paper, an optimized pulse counting method for compensation vector calculation in an electromagnetic dual-weight balancing system is proposed based on a programmable logic controller (PLC). Therefore, if the position of the counterweight is inaccurate, it may result in a wrong adjustment and a larger imbalance of the rotor system. Compensation vector is synthesized by the two counterweights located in the electromagnetic dual-weight automatic balancer.

The accuracy of the counterweight positions in an automatic balancing system deeply affects dynamic balancing.
