  EDUCATIONAL ELECTRIC MOTORS

  Windows/Mac version MP4 Video and PDF Formats ©

    Welcome to the Educational Electric Motors site. We designed a unique and marvelous product to teach students how to build four types of real electric motors. The four types of motors are: Toothpick, Straw, Paperclip, and Cork motors. As a result of this hands-on experience, students will understand the basic assembling and the physics of an electric motor, including the critical roles played by electricity and magnetism when a motor is working. The cost of the materials needed to build all four motors is small, approximately $20. This product was put together by a state certified teacher with 26 years of teaching all levels of physics in the classroom.

    The four motors studied in this educational product can be constructed as a laboratory activity in the area of electricity or as a science project. The materials needed, the guidelines, the required measurements, and the step-by-step planning and construction are clearly explained using text, attractive drawings, and high-quality digital pictures and videos. This product includes videos in MP4 video format and files in pdf format. There are many excellent electronic viewers available to watch the MP4 video files, which most probably your already have in your computer, or that can be downloaded at no cost from the Internet, including Windows Media Player, VLC Media Player, Real Player, and many others. At the bottom of this page you will find the link to download the VLC Media Player, which we consider one of the best.

    With the help of text, drawings, digital pictures, and great looking animations, students are guided step-by-step in assembling each part of every electric motor. An outstanding tutorial that explains the essential role played by magnetism in the work of electric motors is also incorporated.

Motors - Toothpick Motor subtitle

    toothpick motors #1

    The picture above shows a Toothpick motor. As it can be observed, a steel needle penetrates the toothpick. A coil is built around the needle.

    The most important part of the electric motor is the coil, which is where a fluctuating magnetic field is created when the motor is spinning. This educational product explains step-by-step, using text and dozens of digital pictures and drawings, how to make each coil from the beginning to the end. By simply following the sequence of the digital pictures, the students will gain plenty of knowledge to make a coil that will work succesfully.

    This learning experience can be adapted by science teachers as a motivating lab activity in electricity for an entire class. Teachers could use a large model to guide the students in making the coil and other parts of the electric motor. If a computer lab is available, the students just need to follow the instructions shown in the different computers. After all the needed materials have been obtained, it takes between 1 and 2 hours to assemble and test successfully a toothpick motor.

    The animations of about 40 different motors are incorporated in the software.

    Paperclip Motor subtitle

    Another electric motor that students can construct is the Paperclip motor. This motor is the simplest of the four to make. To assemble this motor takes about 10 minutes, which is basically the time needed to make the coil. Students are suggested to construct several coils, each one containing from 1 to 20 loops of wire, and later check which coil appears to be turning the best.

    For this project students need to use insulated wire, from gauge 20 to gauge 30, to make the coil. After a coil has been made, a razor blade is needed to scratch off some of the thin layer of insulation. The coil is then supported by two large uninsulated paper clips that have been reshaped, as it is shown in the picture above and in the animation below. The object shown on top of the D size battery is a ring ceramic magnet. To supply the electric current, instead of the D size battery, an old power supply of a cellular phone and a small plastic bottle could be used.

    This oustanding product clearly explains the different materials that are needed to build all four motors, and how to get them. The D size battery, the wire and the magnets can be purchased at Walmart, Home Depot, Ebay, Amazon, and in science supply stores. A good news is that the rest of the materials, a rubber band, a cork, two large paper clips, and a small piece of card board are found in most homes.

    Straw Motor subtitle;

    The Straw motor is basically a larger version of the toothpick motor. The toothpick and the steel needle are substituted for a drinking plastic straw and a straight steel wire, both about 12 cm in length. The wire from a small paperclip is appropriate for this project. The Straw motor requires more electricity and a stronger magnet to operate. Since this motor requires a greater electric current than a toothpick motor, the power supply of an old cellular phone, a 9 volt battery, or a USB power adapter could be used. The complete assembly and testing of this electric motor takes from 1 to 2 hours.

    Cork Motor subtitle

    The central part of this electric motor is a medium size cork. Of the four motors studied, the coil of the cork motor is the one that uses the greatest amount of wire. This motor looks very fascinating when it is turning. It takes approximately 2 hours to assemble the Cork motor.

    Other Motors subtitle

    Besides the four types of motors described above, this product also shows a St. Louis Motor and other types of electric motors of greater power. Even though they are much more challenging to build, students will find beneficial learning about them.
