About this site

In 1997-2000 Stan Pozmantir designed a new type of a simple electric motor based on a reed switch for his 3-year science fair project.

The idea of using reed switches in brushless motors appeared in some patents earlier but was never widely known. Stan was the first to create a simple motor kit – excellent educational tool by far exceeding the parameters of most do-it-yourself motors.

He also created several other types of brushless motors. All of them were extremely simple, and at the same time stable, powerful, efficient, and fast. Recently we modified and improved these motor kits.

Our motors were widely used for educational purposes in more than 130 schools, colleges, universities, and other organizations in the United States and more than 40 other countries. More than 17000 customers successfully built the motors from our kits using simple and clear instructions.

These motors always work without any struggle or frustration. Build success rate for our brushless motors is 99.97%!

About Simple Motors, LLC

We are in business since 1999 when this site was originally published. Our company, Simple Motors, located in Plano, Texas, is always fully operational.

Time has passed since the days of the original development of these motors. My son Stan is pursuing other interests and does not continue this project anymore.

We tried to preserve the original information on this site but also added a lot of additional motors, parts, kits, etc. with easy to understand explanations and easy to follow instructions. Recently we expanded our Experiments section and developed new tools to help you with your projects. Also we started a new line of QuikLock motors – excellent kits for schools, universities and even for birthday party activities!

New! Watch nine of our most popular simple brushless motors in a video on our YouTube channel.

We will always try to do our best to keep all of our customers happy.

Stan’s information about his project (as published in 2002)

Hi! My name is Stan Pozmantir. I am an 11th grader at Plano East Senior High School in Plano, Texas.

In 1997-1998 I designed a new type of simple brushless motor for my school science fair (disclosure document filed with US PTO). It is a reed switch based motor. This motor is very simple but at the same time fast, reliable and efficient. It is also easy to understand its principles of operation. This is how my original project looked:

My second year research was devoted to the further development of this motor. At this time I improved and simplified its design. It allowed me to start this business.

For my 1999-2000 project I designed and built 7 more different brushless motors. All of these motors shared a common design, and thus I could easily compare them together. Several of the motors that I used in my project were modified and are now available as kits on this site. They include the transistor controlled reed switch motor, the optointerrupter motor, and the motor based on the Hall effect. These motors were simplified to have the minimum number of parts and to operate as efficiently as possible.

This was my project at district science fair:

We made a decision to make Stan’s 3-year science project research papers publicly available. You may use them as a reference for your project.

This 3-year project was very successful. Here is the full list of awards I received:

  • Grand Prize at Dallas Regional Science Fair in 2000 (Senior division) and 1999 (Junior division).
  • Outstanding Achievement in Research and Presentation of Engineering Knowledge Award from Institute of Electrical and Electronic Engineers at the 2000 Intel International Science and Engineering Fair at Detroit.
  • 1st place in the Engineering Category and 2nd place in the Physical Science Division at Texas Junior Academy of Science in 2000.
  • Semifinalist in Discovery Young Scientist Challenge in 1999.
  • 1st place in 1999 and 2000 and 2nd place in 1998 in Engineering at Dallas Regional Science Fair.
  • 1st place at the Plano District Science Fair in 1999 and 2000.
  • 1st place and a special award from North Texas Electrical League in 1998, 1999, and 2000.
  • 1st place and a special award from IEEE in 1998 and 2000.
  • Outstanding Project in Engineering award from NSBE in 2000.
  • Best Engineering Project award from NACE International in 2000.
  • Honorable mention at Texas State Science Fair in 1998 and 2000.
  • Graphing calculator from Texas Instruments (DSP Solutions and Related Engineering) in 2000.
  • Expense paid trip to National AAAS meeting in San Francisco in 2001.
  • 4-year scholarship from Southern Methodist University.
  • In 1999 and 2000 this project was displayed at a special exhibition of prize winning science fair projects at The Science Place Museum in Dallas.

Many of these awards also included generous cash prizes that I used to start this business.

I would like to credit my dad for spending a tremendous amount of his time helping me with this project (and for helping me in setting up this site as well). He helped me to go all the way from my initial ideas to the present stage. Not only did my dad teach me how to use the correct tools for the right task and how to conduct the experiments, but he also insisted on making me redo any step that wasn’t perfect (or close to it). I missed so many TV shows because of this!!! I also need to credit my mom for soothing tensions between my dad and me from overheating.

I worked on these motors for 3 years nearly every week, but now I need to concentrate on my school assignments. Homework at high school is taking more and more of my free time away. Since I am currently going to Senior High School I have almost no spare time and I have decided to concentrate more on school work. However, we still take orders for kits and answer your questions. Sometimes if I have some free time I will also respond to e-mails. I am really glad that my father is offering to help me again with this business. His help allows us to respond to all business matters promptly and keep all of our customers satisfied.

With whatever free time I may have, I like to play hockey (both ice and in-line) and to go skiing/snowboarding (whenever possible). I also enjoy listening to music, especially rock/alternative.

Thank you for visiting this web site. I hope you liked it. I would appreciate any comments you may have.
