About this item
- EASY OPERATION ----No Manual at all. Set the rotor to the board, Levitating success on the model, set the model 45degree direction under the light resource. Give the rotor a gently push, it will run smooth.
- HIGH-TECH ORNAMENT THAT COMBINES THE MAGNETIC AND ELECTRIC FIELD ----The Mendocino Motor is a magnetically levitated, solar powered electric motor. The motor consists of a spinning shaft that is held up by repelling magnets, stabilized by resting a point against a wall. It is powered by solar panels mounted on the spinning shaft, which generate currents through coils of insulated wire, and rotation.
- ENTERTAINING---- The motor rotor can rotate under weak light source. If the light stronger, the rotor rotating speed will be faster. The solar panels which equipped on the rotor convert sunlight to power and drive the model run freely.
- PRIORITY GIFT OPTION FOR MANY APPLICATIONS----It is an amazing and fantastic product at this price. Its elegant gift package makes it spruce up and presentable. It has a wide range of application as, great gift for Kids' science project, Physical/mechanical learning, teacher’s Demo props on the class, birthday gift for friends, families, parents, kids, etc. Many of our customers come from school, colleague, etc.
- AMAZING CONVERSATION PIECES ON YOUR DESK ----Decorative and impressive, it's proven to be a conversation starter to impress your visitors. It’s a cool piece of art even just stands on your desk.

IMPORTANT INFORMATION YOU NEED TO KNOW BEFORE ORDER:
Obviously, this solar model is highly related to sunlight. The solar panels which equipped on the model convert sunlight to power and drive the model run freely. According to sunlight characteristic, the power from the sunlight is always changing because of sun angle and intensity of the sun's rays. You can’t expect this solar model rotor run in a constant speed smooth. It’s not an electrified product which can set constant speed, and no rotor shake.
In the powerful noon time, the model rotor will run freely, speedily, and stably. Oppositely, it performs a little bad in the morning or late afternoon, because of no enough power from the sun. It may act out no stable, a little shake, run slowly. It may even drop from the shelf board too. This is a normal phenomenon instead of product “defective”, it’s decided by sunlight changing.
Features:
Model:ST41
Speed:300-1500r/min
Size: 130*76*75MM
Play steps
1. Bring the model near the window or near a suitable light resource. Don’t put the model on steel desk, it will affect the performance. (set the model 45degree direction under the light resource.)
2. Set the rotor to the board, levitating success on the model
3. Give the rotor a gently push, it will run smooth.
4. The magnet is fragile, please avoid the Magnetic suction to each other and damage.

Customers are dissatisfied with the stability of the science fundamentals kit. They mention that the rotor is out of balance, it wobbles, and the motor was wobbling a little. The wobble starts to resonate and compound enough that the unit falls off during spin up. Some say that the weight is not balanced well enough and it keeps falling.

Customers are dissatisfied with the content of the science fundamentals kit. They mention that it's not balanced very well, has no simple way of correctly balancing, and likes to off balance itself. The unit is somewhat unbalanced on rotation, and the rotor is out of balance. The motor/engine in place is misaligned, and it falls off.
"...The only problem is that it's bit off balance, so I have to bend the shaft a little bit, but it runs really fast !!!..." Read more
"...Returned for a second one that was unbalanced and crashed at high speeds." Read more
"...Enough to actually feel a bit of breeze off the fan.2. Poorly balanced. At really slow speeds and really fast speeds, it stays pretty stable...." Read more
"...I think it has balance issues - seems to be somewhat balanced along its axis, but is not balanced end to end, so it doesn't run level...." Read more

There was a problem filtering reviews right now. Please try again later.
All that being said, It got to me VERY quickly, in perfect condition and very carefully packaged and protected. It was even wrapped in aluminum foil, I suspect to function as a Faraday cage to protect the electronics within. That is something I have never seen before but, if that was their intention, I am impressed with the fact that they took that precaution.
If you are looking for something that will excite and entertain you with lots of action, you may be disappointed with this device. If, on the other hand, you are looking for something that is well designed and elegantly displays some amazing laws of physics, this will not only please you but, it will also make you happy to share with others and to watch it function.
I have not included any videos or pics because there are already plenty of those here. Suffice it to say that it came right our of the box, meticulous wrapping and just started working perfectly!!! It is precisely balanced and regardless of some complaints I have seen posted about having gotten units that were out of balance, this one spins smoothly and with stability at all speeds and in all forms of light. Just FYI, it seems to function best if the light source is coming from the side of the unit, at a 90 degree angle to the solar collector (Armature or, spinning part). Another thing I have discovered that I have not seen mentioned in other reviews. If you place it in such a manner that the light IS coming from one side of the armature, it will rotate towards the light source. If while it is spinning, you carefully turn the unit around 180 degrees from the light source, it will slow and reverse direction to once again rotate towards the light. It will spin fast enough in direct sunlight to be totally a blur. With lesser light sources, like facing a window just before the sun comes up or, just after it goes down or, from an electric light, it will spin consistently but slowly, still fun to watch and be amazed at. If the light source is or gets too dim, it will eventually slow and stop spinning.
IF YOU ARE EVEN SLIGHTLY INTERESTED IN SCIENCE, THE LAWS OF PHYSICS THAT CONTROL OUR UNIVERSE OR, IF YOU ARE A TEACHER…THIS DEVICE IS FOR YOU. I would buy it again in a heartbeat and in fact, I plan to order several more of these to send to friends and family as Christmas gifts. This is something just about anyone would love to own and watch.
(One issue: it came without the propeller being attached to the shaft. I am not handy, but was able to fix it. I had to ream out the hole in the end of the shaft a little, using the blade of a pair of small sewing scissors. I was then able to twist the propeller onto the shaft enough so that it does not fall off. I at first installed it off center so that that the motor was wobbling a little, but after pushing the propeller on a little more, it centered itself and now it runs great. I put a battery powered spotlight on it and had it running at perhaps 1000 rpms and it runs smooth. In fact, no wobble of the motor now at any RPM speed, fast or slow. Great product!
The only problem is that it's bit off balance, so I have to bend the shaft a little bit, but it runs really fast !!!
Then, it goes flying off into the furniture...
Hahahahahahaha
None the less, 5 stars !!!!!!!
LOL
But....
If we made a giant one of these things, it should be able to drive an alternator as long as there's decent light.
Just this little thing has some strength to it.
I put a decent amount of pressure on it and it still maintained it's momentum.
The point is that there's free energy out there all around us.
Between wind and solar... Etc.... we can cut down emissions and need for oil in no time, if the oil lobbyists stopped giving campaign money to the upper crust of our politicians.
The minute Ronald Reagan took down the solar panels on the Whitehouse and decided not to use the metric system is why we're in the place we're at.
Funny how it seems like things have only gotten worse in the political arena.
Deep State Trump is now hitting that ball out of the park for the Lobbyists with more lies.
Maybe once winters no longer exists and all the ski slopes close down we'll start to open our eyes.
Until then, I hope more companies like this sell these toys to show our youth that there really is hope out there for the future of the world.
Sorry, not being political, just naming humans that stopped progress in the world.
In hundreds of years from now, Historians will not look kindly on the turn of this century.
Honestly it's an embarrassment that it's also recorded on video for them, but sadly it is.
Anywho, have a great day and do something nice for another person today !!!
The future is wide open, as long as we strive towards that, the rest will follow.
