“Awesome!!” were the exact words my electronics teacher said when I turned in this motor for a 250 point project, and I got all 250 points. Thanks!!

The outreach activity is on July 16. I would like to use custom kit 2 with the battery holder. 130 students have said that they will come to the program, but they don’t usually all show up. It’s a two week program and my activity is toward the end.”
“The program went really well today!
For the wire for the electromagnet, one of the undergraduate students stood with the spool of wire on a stick. Each girl took the end of the wire, walked to the other end of the room (it’s a large room), then walked back, winding the wire around her arm. One of the pictures shows the girls in line waiting for their turn.
Most of the motors worked. Here are the reasons why some of them didn’t work: Some of the girls weren’t careful enough when they aligned the rotor on the stands, so they had too much friction. A few of them got their wire tangled when they were winding the electromagnet, but they were tired of winding and didn’t want to start over, so their electromagnet wasn’t strong enough. They broke a few reed switches bending them too sharply (but we had plenty). And a few motors didn’t work because the girls hadn’t removed enough of the insulation from the lead wires to make the connections. (This one was easy to fix once the problem was found). Quite a few of them didn’t understand why they had to figure out which way to connect the circuit to get the magnets to repel. In some ways this was good, because when I was helping them fix the motor, I could explain more to them about how the motor worked. We talked the beginning before they started to put their motors together about how motors worked, but it went too quickly for them all to understand.”

My students are VERY low functioning academically. All have severe behavioral issues and most have additional learning disabilities as well. The fact that they did all of the work, and then problem solved independently when things didn’t turn out as we had theorized was an outstanding lesson for them!
Thanks again for letting me know about your site and creations. They are a definite asset and valuable resource to my classroom.

I am a computer teacher at an elementary school right now (I have 20 years of experience with computers from my electrical engineering work) and I am teaching electricity in science class to our fifth graders. I will definitely be using your motor kits and web site during my instruction in April and May, 2001. I will be teaching electricity again to the 5th graders here at Tate’s School of Discovery.

* Bob Durbin, who makes “impossible bottles” and other puzzles – look at couple reed switch motors he made: GOLF BALLS GO ROUND, PEPSI CAN MOTOR with dwarf hamster inside 🙂
The motor was a big hit in my boy Garrett’s 9th grade science class today.

I used spare 12vdc power supplies instead of batteries. To burn off extra watts we put a 6vdc flashlight bulb in the circuit, which added a positive reed-switch state indicator!
Anyway, thanks again.

My daughter built motor kit 13 for an 8th grade science project. She had a total blast doing so(which is always a treat for a mom to see her 13 year old enjoy any type of school work). With minimal help from me, she did a great job and the motor worked as it was supposed to. Not only was building the motor a great experience, customer service from this company was also handled perfectly. I contacted Serge P. directly via telephone and he was easily reachable and extremely helpful and willing to answer any questions I had. From start to finish, this was a wonderful experience for both my 13yr old daughter as well as myself, her mom.
I thank you so much for your help and service. I would and will highly recommend this website to anyone in this market.

I Built a brushless DC gatorade bottle motor complete with bearings on the shaft, liquid cooled hand wound coils, and 3 rare earth magnets; for a course that i am enrolled in at Dixie Applied Technology College. After i had set the bar for the rest of the class with this motor, I was trying to figure out how to eliminate the reed switch with a hall effect sensor. When I discovered your web site i was very pleased about it and will be converting my bottle motor to use the hall effect sensor(s). I will mention this web site it to my professor for the Industrial and Facilities Maintenance course.
Jason Ray
I received the parts that i had ordered today so I could convert my reed switch brushless gatorade bottle motor; over to a hall effect sensor system. after mounting and routing the various wires I tried it out and it works nicely. Now i’m trying to get the same if not more speed that i was getting with the reed switch. My thanks to you and your web site.

Thank you for the DC motor kit, the updates on shipping status and the on time delivery. Well done on your part and I wish we had this when I was in school.

From the moment I found “Simplemotor.com” they at “Simplemotor.com” have exceeded expectations. I selected the #4 project for my grandson to introduce him to electromagnetism; Thoroughly, pleased… Thank-you!

I bought motor kit 10 for homeschooling and I’m well pleased with it. My student had to persevere in soldering and troubleshooting so that’s good and I had to replace the hall effect transistor twice because we broke the leads but that’s OK and I’m quite thankful. He’s yet to do the RPM measurement but done other than that. I also ordered kit#9 plus the solar panel for the next one.

I have been an engineer for more than 30 years where I involved in research work and machine development in university laboratory and later in semiconductor industry. I was granted a handful of patents from my inventions during my earlier research work, and I continue inventing today. I wanted to build some simple motors myself and learn the basics. I was very happy when I discovered SimpleMotor.com and so I bought a Kit for my experiment on Pulse Motor. The instructions are very clear, product was packed nicely, and THANKS go to Serge for his patience clarifying my questions — very promptly. It took me just a few hours building my first Pulse Motor that works perfectly. I will now take the challenge to modify the simple motor to explore further and learn new things.

Fantastic kit project I enjoyed every Minuit building the motor getting it to work and testing the different sensors supplied and seeing how they worked in the circuit was my main reason for building the 4 in one kit, which I have learnt a great deal from which also helped me get my Bedini project off the ground and is now all working and all thanks to your kit that has taught me to understand more about electronic magnet motors.
SimpleMotor.com THANK YOU. I AM VERY HAPPY 🙂

I’m ordering 2 more of kit #9 today plus the solar panel since we got kit #10 (also #9) before and have a few components the next child will be able to reuse. (multimeter, color wheel, something more I can’t remember at the moment) All of kit #9 is needed for each student because they need the experience building their own. This is the best hands-on option I’ve found for learning these concepts.

Had a few students assemble the motor in about 20 miniutes, it started a lot of questions of how and why and opened the eyes of everyone when it started running, they gathered around and wanted to try their skill at assembly I will be ordering these little kits in bulk from now on. they are a really good teaching tool for electrical beginners.

Oh wise and mysterious purveyors of fine electric motor kits –
Just thought I’d drop you a note of thanks.
Today, for the second time, I led a class of grade schoolers (6th grade this time, 4th grade last time) through the process of assembling your #17 kits. And for the second time, with a bit of help from me (especially on correctly scraping insulation from wire) we got all of the motors up and running.
I don’t know if this business generates a significant amount of revenue for you, but I can say that it absolutely captures the imagination of grade school kids. I’m going to take some notes on what to do differently next time and may ask the school to help fund the activity so we can get kit 11 instead of the more tedious #17
But anywho, it’s wonderful that you provide this service – thanks for doing what you do! I look forward to ordering more kits for next year…and may get some for myself too, to show the class as an example before they get going.

I was so happy and pleased to have found Serge’s simplemotor.com about 12 years ago. Ever since I was 11 years old I built brushed motors and eventually the brushes would wear out or they wouldn’t work due to alignment issues. These brushless motors remove those problems and they can get to very high revolution/minute.
My sons and daughter have built Kits #1-7. The most recent purchase was Motor Kit #11 because I wanted to build a motor in less than an hour. Now that I have done that (and made some mistakes along the way) I believe I can build a second one in less than 30 minutes. I love these kits – they are so much better than the motors I build as a child that has brushes in them and I love to see them work first time, every time.
