Features: This book introduces in a diagrammatic form the usage methods, common failure causes, repair techniques, inspection methods, and testing methods of three-phase AC low-voltage medium and small asynchronous motors. It visually presents their complex technical issues and operational processes, making learning easier. The content of this book is all sourced from experienced electric motor manufacturing and repair enterprises in China, and it comprehensively incorporates the author's many years of practical experience in motor repair, thus possessing strong practical value. Additionally, the motor repair data at the back of the book provides convenience for reference. The main contents of this book include:
Common knowledge of three-phase asynchronous motor usage;
Structure and disassembly of ordinary three-phase asynchronous motors;
Common failures and causes of ordinary three-phase AC asynchronous motors, as well as the removal and fabrication of windings, general embedding and wiring processes, and examples of embedding and wiring for the four common types of windings;
Inspection and testing before dipping paint after stator embedding;
Dipping paint and drying;
Repair of aluminum-cast rotors;
Repair of mechanical components;
Specific failures and maintenance methods of three-phase wound-rotor asynchronous motors;
Structures and usage, maintenance characteristics of explosion-proof motors, electromagnetic speed-regulating motors, three-phase phase-switching motor, submersible pumps and matching motors, and self-braking type motors;
Usage methods of testing instruments and measurement circuits;
Overall inspection and testing after repair.
