Китайский, без щёточный генератор, ремонт.

Introduction

This tutorial provides a step-by-step guide to repairing a Chinese brushless generator without the need for rewinding. The focus will be on practical techniques and tips to successfully troubleshoot and fix common issues associated with these generators.

Step 1: Gather Tools and Materials

Before beginning the repair, ensure you have the following tools and materials ready:

• Multimeter for voltage and continuity testing
• Screwdrivers (flathead and Phillips)
• Wrenches or pliers
• Replacement parts (if needed)
• Safety gear (gloves and goggles)

Practical Advice

• Make sure your workspace is clean and well-lit.
• Wear safety gear to protect yourself from any debris or electrical hazards.

Step 2: Disassemble the Generator

Carefully take apart the generator to access its internal components.

1. Remove the outer casing:

   • Use the screwdriver to unscrew all screws holding the casing.
   • Keep track of screws and small parts to avoid losing them.

2. Take out the rotor and stator:

   • Gently pull out the rotor and stator for inspection.
   • Be cautious not to damage any wires or connectors during this process.

Practical Advice

• Take photos during disassembly to help with reassembly later.
• Label any wires or connections to ensure you remember where they belong.

Step 3: Inspect Internal Components

Once the generator is disassembled, inspect the internal components for damage.

• Check the rotor and stator:

  • Look for signs of wear, burns, or corrosion.

• Test connections and wires:

  • Use the multimeter to check for continuity in wires and connections.

Common Pitfalls to Avoid

• Do not force any components apart, as this may cause further damage.
• Ensure the generator is unplugged before inspecting internal components to avoid electric shock.

Step 4: Repair or Replace Damaged Parts

Based on your inspection, repair or replace any components as necessary.

• For minor damages:

  • Clean corroded contacts and tighten loose connections with appropriate tools.

• For major damages:

  • Replace damaged components with new ones, ensuring they are compatible with your generator model.

Practical Advice

• Use original parts from the manufacturer to ensure compatibility and performance.
• Refer to the generator’s manual for specific replacement part numbers.

Step 5: Reassemble the Generator

Once repairs are complete, reassemble the generator in reverse order of disassembly.

1. Reinsert the rotor and stator:

   • Ensure they are positioned correctly and securely.

2. Attach the outer casing:

   • Carefully screw the casing back together, ensuring no wires are pinched.

Practical Advice

• Double-check that all screws are tight and all components are correctly positioned before powering on the generator.

Step 6: Test the Generator

After reassembly, it’s time to test the generator to ensure it works properly.

• Connect the generator to a power source:

  • Make sure all safety precautions are followed.

• Start the generator:

  • Observe its operation for any unusual noises or performance issues.

Practical Advice

• If the generator does not start, recheck your connections and internal components for any overlooked issues.

Conclusion

In this tutorial, we've covered how to repair a Chinese brushless generator without rewinding. Key takeaways include gathering the right tools, safely disassembling and inspecting the generator, repairing or replacing damaged parts, and thoroughly testing the unit after reassembly. For further maintenance, consider regular inspections and cleaning to prolong the life of your generator.
