12000W Electric Generator12000W Electric Generator

Do you find yourself frustrated with power outages and in need of a reliable backup power source? If so, constructing your own electric generator may be the perfect solution. In this article, we will provide you with a comprehensive guide on how to create a 220 Volt 12000W electric generator from the comfort of your own home. With our easy-to-follow instructions, you can have your very own generator up and running in no time.

Materials Required

Before we begin, let’s gather all the necessary materials for this project. You will need:

  • An engine (preferably a 20 horsepower engine)
  • A magnetic rotor (12000W)
  • A voltage regulatorWooden Plates
  • A fuel tank
  • A power outlet box
  • Electrical wires
  • A winding machine
  • A metal  shaft
  • Tools (wrenches, screwdrivers, pliers, etc.)

Step 1: Constructing the Frame

The first step is to construct a sturdy frame for the generator. You can use metal pipes or angle irons to create a solid structure. Ensure that the frame is large enough to accommodate the engine, generator head, and fuel tank. Weld the pieces together to create a robust frame.

Step 2: Mounting the Engine

Next, mount the engine onto the frame using bolts and nuts. Ensure that the engine is level and centered on the frame.

Step 3: Installing the Generator Head

Now it’s time to install the generator head. Attach the generator head to the engine using a coupling. Ensure that the coupling is tight and secure. Connect the wires from the generator head to the voltage regulator.

Step 4: Adding the Fuel Tank

Attach the fuel tank to the frame, ensuring that it is positioned above the engine to allow for gravity-fed fuel flow. Connect the fuel line to the engine and fuel tank.

Step 5: Wiring the Electrical Components

Connect the battery to the voltage regulator. Run electrical wires from the voltage regulator to the power outlet box. Ensure that the wires are properly insulated and secured.

Step 6: Testing the Generator

Before starting the generator, double-check all connections and wiring. Once everything is in place, start the engine and test the generator. Use a voltmeter to check the voltage output. Adjust the voltage regulator as needed to achieve the desired output.

Frequently Asked Questions
