First, learn electrical technology, AC and DC circuits, and relay control circuits. Electronic technology, rectifier inverter amplification switching circuit frequency conversion technology. Various electronic control technologies and learning. The principles and methods of use of various electrical instruments, thermal instruments and maintenance tools.
Learn the construction principles of DC motors, three-phase AC asynchronous motors, single-phase AC asynchronous motors, and power tools. Analyze the wiring principles and rules of three-phase motors, single-phase motors, multi-speed motors, submersible pump motors, and series motors. Draw unfolded diagrams and wiring diagrams of various motors to make theoretical preparations for overhauling the motor stator windings. In terms of operational skills, I practiced while learning, dismantling old windings, recording data, setting molds, winding coils, embedded wires, wiring, dipping and assembling experiments, and mastered the process of overhauling motors. At the same time, I also take into account the maintenance skills of power tool welding machines. Practice is the main focus, and hands-on teaching is the main focus.
