Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.

Use a hydrogen-oxygen flame welding machine to weld the coil lead wires of electronic devices such as motors, motors, and transformers.

working principle:
Water is composed of hydrogen and oxygen. In a specific electrolytic cell, water can be decomposed into hydrogen ions and hydroxide ions. The hydrogen ions move to the cathode to generate hydrogen gas, and the hydroxide ions move to the anode to generate oxygen. Hydrogen is a fuel. Oxygen can be used to support combustion. It can be ignited by a specific hydrogen-oxygen flame gun to form a hydrogen-oxygen flame, which can quickly weld the enameled wire.

The motor generally includes a stator and a rotor, with a core and windings on the stator or rotor.
The insulated wire is winded by a certain shape to form a coil. The coil can be a turn or a plurality of turns. A plurality of coils form a group of units and is called a coil group. A combination of a plurality of coils or coil groups constituting one phase or the entire electromagnetic circuit becomes a winding .
