CARA MEMBUAT ALAT PARUT KELAPA DENGAN DINAMO MOTOR DC 779

Introduction

In this tutorial, we will guide you through the process of creating a coconut grater using a DC motor model 779. This project utilizes a pulley system and a DC PWM dimmer for speed control, making it a practical tool for efficiently grating coconuts. This guide is perfect for DIY enthusiasts looking to enhance their kitchen tools with a homemade solution.

Step 1: Gather Your Materials

To start, collect the following materials:

• DC motor 779
• Pully (appropriate size for your motor and grating mechanism)
• Dimmer DC PWM speed controller (12V-40V, 10A)
• Grating surface (e.g., metal or plastic sheet)
• Mounting frame or base (wood or metal)
• Fasteners (screws, nuts, and bolts)
• Electrical wires
• Power supply (compatible with your DC motor)

Step 2: Assemble the Frame

1. Create the Base: Cut your mounting frame to a suitable size that can hold the motor and grating surface securely.
2. Mount the Motor:
   • Attach the DC motor to the base using screws.
   • Ensure it is stable and can withstand the vibrations from the motor running.
3. Install the Grating Surface:
   • Position the grating surface on the frame above the motor.
   • Secure it so that it aligns with the motor shaft.

Step 3: Install the Pulley System

1. Attach the Pulley to the Motor Shaft:
   • Fit the pulley onto the shaft of the DC motor.
   • Ensure it is tightly secured to prevent slippage during operation.
2. Position the Grating Surface with Pulley:
   • Align the grating surface with the pulley so that it can effectively transfer motion.
   • Adjust the height as necessary for optimal grating.

Step 4: Connect the Dimmer and Wiring

1. Wire the Motor to the Dimmer:
   • Connect the positive and negative terminals of the motor to the corresponding outputs on the dimmer.
   • Ensure all connections are secure to avoid any short-circuiting.
2. Connect the Power Supply:
   • Attach the power supply to the input terminals of the dimmer.
   • Make sure the power supply voltage matches the requirements of the motor and dimmer.

Step 5: Test the Coconut Grater

1. Power On the Device:
   • Turn on the power supply and adjust the dimmer to test the motor's speed.
   • Start at a low speed to ensure everything is functioning correctly.
2. Grate a Coconut:
   • Place a coconut on the grating surface and observe how well the device performs.
   • Adjust the dimmer as needed to find the optimal speed for grating.

Conclusion

You have successfully created a coconut grater using a DC motor 779. This DIY project not only enhances your kitchen tools but also provides a hands-on experience in basic electrical and mechanical assembly. For further improvement, consider adding a safety cover or enhancing the grating surface for better durability. Enjoy your homemade coconut grater and happy cooking!
