Added: 2026-05-31

[00:00:00]Welcome back to the channel. Today you're about to see something incredible. A fully functional DIY wooden BLC motor built using just 20 magnets and 15 coils. If you think a high performance motor requires expensive metal parts, complex machinery, this project is going to change your mind. What if I told you that with the right design, precise magnet placement, and carefully wound coils, a simple wooden structure can be transformed into a powerful brushless DC motor? In this video, we'll take you through the complete process from preparing the wooden frame and arranging all 20 magnets to winding and installing the 15 coils for smooth and efficient operation. But here's the exciting part.

[00:00:38]Once everything comes together, you'll see the motor come to life and spin with impressive performance. Whether you're a DIY enthusiast, a maker, or simply curious about electric motors, this build is packed with valuable insights.

[00:00:51]So stay tuned because this is a project you won't want to miss.

[00:01:00]Now we will start marking the positions for all 15 coils on the wooden plate.

[00:01:05]This step is extremely important because the accuracy of these markings will directly affect the performance and balance of the BLC motor. Before making any marks, make sure the wooden plate is clean and the center point has already been identified. Using a ruler, protractor, or a printed template, carefully divide the circular area into equal sections so that each of the 15 coils has the same spacing.

[00:01:40]Take your time during this process as even a small mistake can cause alignment issues later during assembly. Once the measurements are confirmed, use a pencil or marker to clearly indicate the position of each coil on the plate.

[00:01:56]After completing all the markings, double check the spacing and alignment one more time. A well-marked stator layout will make coil installation much easier and help ensure smooth motor operation when the project is finished.

[00:02:16]This careful preparation lays the foundation for a successful build.

[00:02:22]Now we will fix the rotor onto the wooden plate and carefully check its alignment.

[00:02:32]This is a crucial step because the rotor must rotate freely without touching any part of the stator.

[00:02:44]After mounting it in position, slowly spin the rotor by hand to observe its movement and identify any wobbling or imbalance.

[00:03:04]If any adjustments are needed, we will carefully reposition and secure the rotor until it sits perfectly in the center.

[00:03:26]Proper alignment helps reduce friction.

[00:03:38]improves efficiency and ensures smooth operation.

[00:03:50]Once everything is correctly set, the motor will be ready for the next stage of assembly.

[00:03:58]Now we will start making the bobbins for our motor coils.

[00:04:06]For this we need to cut 15 wooden pieces, one for each coil position.

[00:04:27]It is important that all the pieces are cut to the same size so that every bobin has a uniform shape and provides consistent space for winding the wire.

[00:05:19]Heat.

[00:05:41]Heat.

[00:06:05]Once the wooden pieces are prepared, we will attach small wooden blocks to them using strong wood glue. These small pieces will act as side supports and help create the basic structure of the bobin. As you can see in the video, carefully position each small wooden piece and make sure it is properly aligned before the glue dries. Taking extra time during this step will help achieve a cleaner and more professional result. After the glue has fully set and the wooden structure becomes firm, we will move on to the next stage. Now we will fix PVC pieces onto the wooden frames exactly as shown in the video.

[00:06:38]These PVC pieces will form the center section of the bobbin and provide a smooth surface for winding the copper wire later. Make sure each PVC piece is securely attached and positioned correctly so that all 15 bobbins remain identical. As you can see, the combination of wood and PVC creates a strong, lightweight, and durable bobbin design. This simple construction method is cost-effective and easy to replicate using commonly available materials. Once all 15 bobbins are completed, we will have a solid foundation for winding our coils, bringing us one step closer to completing the DIY wooden BLC motor project. Be patient and focus on accuracy because well-made bobbins will make the coil winding process much easier and more efficient.

[00:07:22]Now, we are ready to begin one of the most important stages of this project, winding the coils. For this build, we are using AWG21 copper wire, which has a diameter of approximately 0.723 mm. This wire size provides a good balance between current carrying capacity and ease of winding, making it suitable for our DIY wooden BLC motor. As you can see in the video, we will start winding the wire onto the bobbins that we prepared earlier. It is very important to keep the winding neat, tight, and consistent throughout the process. For each coil, we will wind 40 turns of wire.

[00:08:12]Count the turns carefully to ensure that every coil has exactly the same number of windings. Consistency is essential because coils with different turn counts can affect the motor's performance and efficiency. While winding, make sure the wire is laid evenly across the bobin without overlapping excessively or becoming loose.

[00:10:19]A clean winding pattern not only looks professional but also helps maintain uniform electrical characteristics across all the coils.

[00:10:58]As shown in the video, continue wrapping the wire in the same direction for every coil. Maintaining the same winding direction is critical for proper phase arrangement and smooth motor operation.

[00:11:08]After completing the first coil, repeat the exact same process for the remaining coils.

[00:11:56]Take your time and follow the same method for all 15 coils, ensuring that each one receives 40 turns and is wound with the same orientation and tension.

[00:12:04]As you watch, you can see how each completed coil matches the others.

[00:13:20]creating a uniform set ready for installation. Once all 15 coils have been wound, carefully inspect them to verify that the turns are correct and that there are no damaged or loose sections of wire. With all the coils completed in the same way, we will have a balanced and consistent stator assembly, bringing us another major step closer to completing our DIY wooden BLC motor.

[00:17:22]Now that all 15 coils have been wounded and prepared, it is time to install them onto the wooden stator plate. Earlier in the project, we carefully marked the positions for each coil on the wooden plate. Those markings will now guide us in placing every coil accurately around the rotor. As you can see in the video, we begin by applying a suitable amount of glue to the marked locations on the wooden plate. Be careful not to use excessive glue as too much adhesive can make the installation messy and may interfere with the final arrangement of the coils. Once the glue is applied, gently place each coil onto its designated mark and press it firmly into position. While fixing the coils, it is very important to maintain equal spacing between them. The coils should be arranged evenly around the rotor following the markings that were made earlier. Proper alignment ensures that the magnetic field is distributed uniformly when the motor is operating.

[00:18:14]Take your time during this step and check each coil before the glue begins to set. Continue installing the remaining coils one by one following the same method as shown in the video. Every coil is positioned in the same orientation and fixed securely to the wooden plate.

[00:18:43]This helps create a neat and organized stator assembly while also making the wiring process easier in the next stages.

[00:19:00]After all 15 coils have been installed, carefully inspect the entire arrangement. Make sure every coil is firmly attached and that none of them are touching the rotor.

[00:19:23]Slowly rotate the rotor by hand to confirm that it spins freely without any contact or obstruction.

[00:19:56]If any coil appears misaligned, make the necessary adjustments before the glue fully cures.

[00:22:26]At this stage, the stator begins to take its final shape. With all 15 coils securely fixed around the rotor, our DIY wooden BLC motor is starting to come together, and we are now ready to move on to the electrical connections and the next phase of the build.

[00:24:04]Now we are moving on to the electrical connection stage of our DIY wooden BLC motor. This is one of the most important parts of the build because the way the coils are connected will determine how the motor operates. As you can see in the video, we have already installed all 15 coils onto the wooden stator plate.

[00:24:20]And now it is time to connect them into three separate circuits. For this motor, the 15 coils will be divided into three circuits with five coils in each circuit. To begin, take the ending wire of the first coil and connect it to the starting wire of the fourth coil, skipping the two coils between them. As shown in the video, this connection pattern helps create the correct phase sequence required for the motor. Next, take the ending wire of the fourth coil and connect it to the starting wire of the next third coil in the sequence.

[00:24:48]Continue following the same connection pattern around the stator. It is important to pay close attention to the coil numbering and wire orientation while making these connections. A mistake at this stage can affect the motor's performance and may prevent it from operating correctly. As you can see, we are repeating the same method for each group of coils. One by one, the coils are connected together following the same sequence and direction.

[00:25:11]Continue this process until all five coils in the first circuit are connected together. Once completed, repeat the exact same procedure for the remaining coil groups. Using the same connection pattern, we will create a total of three separate circuits and each circuit will contain five connected coils. Throughout the process, make sure that all joints are secure and that the wire insulation remains intact wherever required. Neat wiring will make troubleshooting easier and improve the overall reliability of the motor.

[00:27:28]Heat. Heat.

[00:31:41]After completing all three circuits, you will notice that six wires remain unconnected. These six wires are the starting and ending leads from the three coil circuits. At this point, we will configure the motor into a three-phase star connection exactly as shown in the video. To do this, take the ending wires from the three coil circuits and connect them together at a single common point.

[00:32:03]This junction forms the neutral point of the star configuration. Ensure that these connections are strong and properly insulated after joining them together. Now, we are left with three starting wires, one from each circuit.

[00:32:15]As you can see in the video, these three wires will not be connected together.

[00:32:19]Instead, they will be left separate and used as the three-phase input terminals for the motor controller or ESC. These three wires represent the motor's three phases and will be connected later during testing and operation. At this stage, all coil connections have been completed successfully. We now have three balanced coil circuits arranged in a proper three-phase configuration. With the wiring finished and the phase leads ready, our DIY wooden BLC motor is one major step closer to coming to life. The stator assembly is now electrically complete and ready for the next stage of the project.

[00:33:17]Now it's time for the most exciting part of the project. We will connect our DIY wooden BLC motor to the controller and perform its first test. As you can see in the video, all the connections have been completed and the motor is ready to run.

[00:33:58]After powering on the controller, the motor starts spinning smoothly and responds perfectly. The rotor rotates freely with stable movement, showing that the coil winding and phase connections have been done correctly. It is great to see all the hard work paying off. The motor is running efficiently, spinning nicely, and delivering excellent performance. The build has been a complete success.

[00:37:42]And with that, we have successfully completed our DIY wooden BLC motor project. From preparing the wooden parts and building the bobbins to winding the coils, assembling the rotor, making the electrical connections, and finally testing the motor, we have covered the entire process step by step. It has been an exciting journey, and we hope you enjoyed watching this build as much as we enjoyed creating it. Before we finish, we would like to share a few important safety notes.
