Strictly speaking, they are divided. After all, the live line and the neutral line are different.
However, during use, the live and neutral wires can be connected interchangeably, because the neutral wire voltage to ground is always maintained at 0 V and the live wire voltage is sinusoidal, so the voltage has a certain value in a positive and negative cycle, so compared to 0 V, swapping the wiring does not affect the voltage, so the wiring can be interchanged.
When using normal electricity, such as sockets, etc., it is not necessary to distinguish between neutral and live wires. But when it comes to fuses (fuses) and switches, they must be connected to live wires! The neutral line cannot be connected.
Aren't the separate lines of the motorcycle power coil divided into neutral and live wires? What isWhere are these three yellow lines? What is the function of the two wires at the contact level?
Neither of the two output lines of the portable generator are grounded! There is no distinction between live and neutral wires.
A single-phase motor has two windings, the starting winding and the running winding. The two windings are spaced 90 degrees apart in space. A large capacity capacitor is connected in series to the start winding When the run winding and the start winding transmit single-phase alternating current, the current in the start winding leads the current by 90 degrees in the running winding due to single-phase alternating current. action of the capacitor, reaching the maximum value first.
Two identical pulsed magnetic fields form in time and space, causing the generation of a rotating magnetic field inns the air gap between the stator and the rotor. Under the action of the rotating magnetic field, a current is induced. is generated in the motor rotor. The current interacts with the rotating magnetic field to produce an electromagnetic field torque, which turns the motor.
This type of portable generator and grid power supply are two different things! The single-phase network supply is earthed at the end of the transformer. When measuring electricity with an electric pen, the earth is used as a source. reference point, so only the live wire will light up.
Neither end of either output line from the portable generator is grounded! There is no distinction between the live wire and the neutral wire. All windings of the portable generator are charged with electric fields! earth. It has a very high induced potential! Therefore, the electric pen will light up if it needs to be connectedin parallel with the circuit, so just connect one of the wires to ground (connect it to zero).
Detailed information:
1. AC motors are relatively cheap to make.
2. With the development of vector frequency conversion technology, variable frequency motors can be used to simulate direct current.
3. Compared with DC motors, they have enough advantages in simple structure, easy maintenance, low environmental requirements, energy saving and productivity improvement, so that the regulation of the AC speed has been widely used in industrial and agricultural production. transport, national defense and daily life.

The wires coming out of the magneto (generator) coil of the motorcycle are divided into live wires and neutral wires (i.e. power wires and power wires). earth). If there are three yellow wires in the magneto output wire, it should be a 3 phase magneto. These three lines are the output lines of the lighting charging coil. They must be connected to the rectifier and connected to the other three lines of the same color. The two "contacts" you mentioned are the trigger coil wires. I don't know if these are the trigger coil wires. Those equipped with three-phase magnetos generally have DC ignition. trigger coil. One is the trigger coil feed wire, usually one. These are ground wires, both of which must be connected to the igniter to provide the ignition signal from the igniter.
