Research And Design Of Dynamic Balance Emendation Control System On Motor Rotor

With the rapid development of modern industry and the constant improvement of motor industry's status, the demanded quantity of motors for the society is continuously enlarged and the motors' quality is increasingly improved. The original unbalance value generated in the production process of small/medium rotor is the main factor that affects the quality of motor. Therefore, dynamic balancing emendation must be implemented before assembling. With considering the production situation of the domestic motor corporations, taking full advantage of our abundant human resources and satisfying the needs of advanced dynamic balance emendation technology for rotor, a motor rotor dynamic balance emendation controlling system is designed in this paper with the embedded system as kernel, and the key technology is researched, then improved.Firstly, precision correction model of electric motor armatures based on contour milling is established, and the effect of slots distribution on the rotor circumference is analyzed. Metal distribution in axial direction on the magnitude and phase of real unbalance is removed, the milling correction strategy is designed, and the error compensation method based on support vector regression is proposed with full analysis of the error characteristics of dynamic balance machining.Secondly, the structure of rotor dynamic balancing emendation controlling system is designed with analysis of the system requirements. The serial communication protocol between embedded system and Single Chip Micyoco is implemented, and the control means of the stepper motor is researched. Through establishing cross-compiling environment, transplanting system startup boot procedure BootLoader, transplanting and collocating Linux kernel, and building root file system, we build the embedded Linux software platform on hardware platform.Finally, the system software is implemented. With considering the control characteristics of the stepper motor, the device driver of stepper motor is designed and implemented. Based on the research of the QT core mechanism, the QT and is ported and the support of touch screen and the expansion of serial class are implemented. According to the functions and characteristics of QT, the control interface of the motor rotor dynamic balancing is designed and implemented..Experimental results show that the ridding unbalance model of the motor rotor and the error compensation method based on support vector regression effectively improved the machining accuracy and efficiency. The motor rotor dynamic balancing ridding unbalance controlling system could preferably accomplish the dynamic balancing emendation of motor rotor and achieve the expected goal.
