Generator wiring method: how to connect three wires

There are usually two ways to wire a generator: star connection and delta connection.
1. Star connection (also called Y-type connection): Connect the three phase lines (A phase, B phase, C phase) of the generator to the three load terminals respectively. . Then connect the three load terminals to form a common point, which is the neutral line (N line). This connection method is suitable for situations where there is a voltage to ground in the load.
2. Triangular connection: Connect the three phase lines (Phase A, Phase B, Phase C) of the generator two by two to form a triangular loop. This connection method is suitable for loads with non-ground voltage.
It should be noted that when wiring the generator, ensure the correctness and firmness of the connection, and ensure load balance to avoid the risk of damage to the generator caused by uneven current distribution. In addition, check the connection marks on the wiring board before wiring to ensure accurate connection of each power phase and load. If you are not familiar with the wiring, it is recommended to ask a professional to operate it.

The car generator has three or four terminals. The thickest one is the live wire B, which is directly connected to the positive battery live wire. The thinner one marked F is the magnetic field connection post, which is connected to the regulator output. terminal, the other marked E is the ground (ground), which can be connected to the iron or battery ground wire. The four wires marked N are the neutral points and generally do not need to be connected. The regulator also has three wires, the one marked B on the left is connected to the ignition wire of the ignition switch lock, the one marked F on the right is connected to the generator magnetic field, and the ground wire on the side is connected to the nearest iron.

The starter switch has two thick (M8) posts. The lower one is connected to the wiring on the starter through a copper sheet or braided copper wire. You can leave it alone. The upper thick (M8) post Connect the battery high wire to the battery positive terminal. The small terminal (M5) next to the starter switch is connected to the starting line of the ignition switch through a wire (car, van), or connected to the starting line of the ignition switch through a starting relay (large truck, bus).
