MOTOR REWINDING AND REPAIRING TOOLS /ELECTRICAL TOOLS

Introduction

This tutorial provides a comprehensive guide to the tools used for motor rewinding and repairing, particularly relevant for those involved in electrical maintenance and repair. Understanding these tools will enhance your ability to work with motors, which are commonly used in households, especially in India.

Step 1: Gather Essential Tools

To start with motor rewinding and repair, ensure you have the following tools:

• Coil Winding Machine: Used for winding coils with precision.
• Clamp Meter: Measures electrical current without interrupting the circuit.
• Screwdrivers: A quality set like the Taparia screwdriver for various screw types.
• Pliers: Stanley pliers are recommended for gripping and twisting wires.
• Spanner Set: Use a Taparia spanner set for loosening and tightening bolts.
• Drill Machine: Essential for drilling holes or removing screws.

You can purchase these tools through the provided links in the video description.

Step 2: Understand Motor Rewinding Basics

Before diving into the process, familiarize yourself with key concepts:

• Motor Winding: This involves replacing or repairing the wire coils in the motor.
• Single Phase vs. Three Phase: Understand the difference, as the winding process varies significantly between the two.
• Winding Diagrams: Refer to diagrams that illustrate the winding process for different motor types.

Step 3: Preparing for Motor Repair

Follow these preparatory steps:

1. Safety First: Disconnect the motor from its power source to avoid electric shock.
2. Inspect the Motor: Check for visible signs of wear or damage.
3. Gather Your Tools: Ensure all necessary tools are within reach to streamline the process.

Step 4: Disassemble the Motor

To access the winding, you must disassemble the motor:

1. Use the screwdriver to remove screws from the motor housing.
2. Carefully separate the parts to avoid damaging internal components.
3. Take note of how components are arranged for easier reassembly.

Step 5: Remove Old Windings

Once the motor is disassembled:

1. Carefully cut and remove the old wire windings.
2. Note the configuration and number of turns used for future reference.

Step 6: Rewind the Motor

Follow these steps to rewind the motor:

1. Calculate Turns: Determine the number of turns needed based on the motor specifications.
2. Use the Coil Winding Machine: Secure the new wire and start winding according to the noted configuration.
3. Check Alignment: Ensure the wire is evenly wound and not overlapping.

Step 7: Reassemble the Motor

After rewinding:

1. Place the newly wound coil back into the motor housing.
2. Reattach all components in the order they were removed.
3. Secure with screws using the screwdriver.

Step 8: Testing the Motor

Before putting the motor back into use:

1. Reconnect Power: Ensure all connections are secure.
2. Test the Motor: Turn on the power and observe the motor’s operation for any unusual sounds or issues.

Conclusion

By following these steps, you can effectively rewind and repair motors using the appropriate tools. Regular practice will enhance your skills in motor repair, which is a valuable asset for anyone involved in electrical maintenance. Consider taking a course for deeper knowledge or practicing on different motor types to broaden your expertise.
