直流工作原理 & 维修技巧
The seminar will cover DC machine theory and operation, as well as repair tips. Topics will include testing and winding of armatures, 字段, 插极和补偿绕组, 机器工作, 平衡, 装配和最终测试. The theory portion is structured so that it can be grasped by entry-level personnel, while the overall material is in-depth enough that those with 30 years of experience or more will benefit.
Partial list of topics covered in the seminar include:
- 拆卸、测试 & 检查提示
- Comparison and explanation of electrical 测试方法
- Data-taking tips, with emphasis on critical information
- 组装技巧 & 测试方法
The accompanying book is not meant to replace the many good texts that cover the theory and design of DC machines, 但是为了补充它们. Its purpose is twofold: to help the technician understand DC machine theory without complex formulae; and in a larger sense, to record in one place the repair procedures and tips usually learned the hard way during a long career of DC machine repair. It may take a decade or longer for a technician to become proficient and knowledgeable. We hope this book will cut many years from that timeline.
The text begins with DC theory (no math, we promise!), and then follows the logical progression of a DC machine through the service center. Disassembly, inspection and testing are covered in the initial chapters.
Subsequent chapters are organized around the main parts of a DC machine. The final chapters cover assembly, final testing and application issues. Sections focusing on components explain how those parts work, how they are made and how they can best be repaired.
Repair tips gleaned from EASA members’ decades of experience are liberally sprinkled throughout the book. While many texts about DC machines explain how they should work, this is the first (to our knowledge) to discuss all the exceptions that a repairer is liable to run across during a lifetime of working with DC machines. These might otherwise be labeled “lessons learned the hard way,” except that the reader can benefit from having all these special cases collected in one source. 在可能的情况下, it is better to learn by reading than by trial and error; otherwise, the first encounter with a unique design can result in a painful “learning experience.”
A DC machine can be used interchangeably as a motor or generator, simply by changing the connection. Any DC motor can be driven and used to produce power, and any DC generator can be motorized to provide mechanical power. Although this text predominately refers to “motor;” the material applies to both motors and generators.
As with the other EASA publications—Principles of Large AC Motors, 电机机械修理基础, and 根本原因失效分析—each section is designed to stand alone. 少量的重复是有意的, to save the reader from flipping back and forth between sections.
