悬臂吊车无配重计算机速度调节系统设计研究——本科毕业论文总结

The graduation thesis titled "Design of Computer Speed Regulation and Traction System for Cantilever Crane without Counterweight" from Shenyang Aerospace University North Technology College focuses on the research and development of computer-controlled motor speed regulation for cranes to achieve uniform lifting and lowering speeds when the hook is empty or loaded. The thesis provides a detailed introduction to the start-up, speed regulation, and braking of crane motors, proposing and discussing various speed regulation and braking methods, ultimately choosing the series connection speed regulation and reverse connection braking methods for motor control. The research aims to meet the requirements of uniform lifting and lowering, stopping at designated points, and overload protection for cranes with and without loads. The key words of the study include series connection speed regulation, reverse connection braking, and motor speed regulation.
