Electric vehicles are permanent magnet direct current motors. The magnetic field is generated by permanent magnets. The generator does not require winding excitation. The easiest way to convert a battery car engine into a generator is to use PVC water pipes cut into a trapezoid shape with curved surfaces to serve as fan blades. Attach the motor shaft to the iron pipe and add a guide rudder behind it. Finally, everything is connected and fixed via the rotating shaft, and can produce electricity.
1. First of all, the colors of five-core wires can be divided into blue, **, green, red and black. Blue represents the neutral line, **, green. and red represents live wire, and black represents live wire is ground wire. In addition, when wiring, everyone must clearly distinguish them to avoid connection errors and provoabout safety accidents.
2. Second, check whether the five-core wire has a certificate of conformity, whether it has quality system certification, and whether it bears the production date, factory address, specifications, voltage and other details. If these are not clearly marked, this type of five-conductor wire is not easy to purchase.
3. Finally, you can take a five-conductor wire and bend it repeatedly with your hands. If it is soft and has high resistance, it means that the quality of the five-core wire is better. so when buying you can use it Try it with your hands.
