Sntieecr 6 Set Mini Generator Motors 3V-12V DC Motor, Wind Turbine Generator with Mini Fan Leaf and Plastic Motor Holder for DIY Educational Physics Experiment

It’s great for craft or model crafts not very sturdy they’re small so have to work carefully

I can validate that these motors will operate/rotate at a voltage at 1.5VDC. So, a single 1.5 AA Battery will motivate these motors. I'm not sure that his is important to you, but I just wanted to mention it. I was not able to test below this voltage because, as of yet, I don't have a a means to do so.

I used them for a classroom experiment with children and some of them did not work for me.

Great for STEM projects or demonstrating forms of energy with students.

This is one of nine different sets of electrical educational kits that are sold as different "styles" with reviews that are apparently grouped together as if they were all the same product. I am writing only about the set of 6 motors, motor mounts and propellers. Very little power is required. A single 1.5 V L44 button cell was sufficient to power a motor with an attached propeller. The propeller/fan blade takes some force to push onto the shaft and stays securely on. Attaching the positive terminal of the battery to the read lead and negative to black, results is CCW rotation and proper fan airflow from the motor through the propeller. If the leads of two motors are connected red to black, a strong puf of air by mouth will cause the propeller receiving the air to turn the attached shaft thus generating enough electrical power to turn the other mootor. If the leads of a motor are connected to an LED with no series resistor, black to anode (plus) and red to cathode (minus) a strong puff of air by mouth will cause the motor to generate sufficient poower to briefly light the LED. A small 2x2 inch solar cell illuminated by a 1500 lumen bulb held very close to the cell was able to operate a motor - propeller combination. I can not locate the solar cell specifications. It is not from this seller. All combinations of driving propeller and driven propellers styles (4 blade & 3 blade) resulted in sufficient power to light an LED from the power generated by the driven propeller motor/generator combination. The driving motors were powered by 12 volts. Unfortunately operating the motors at 12 volts resulted in two destroyed motors even though the sellers information seems to indicate that is an acceptable voltage. This motor and propeller kit is a good way to demonstrate several aspects of electric energy generation and use.

These are the best motors I’ve ever bought Five out of five stars

Bought this for a wind turbine project. The product suggested that the motor generates electricity when spun, however that is not the case. I wired the motor to some low voltage lights, and used a blow dryer to spin the turbine. The light did not turn on. I even connected the light to a battery beforehand and it worked perfectly.

Some 3D Print Suggested Buying This Motor for its 3D Print. Great Deal and Worth it.

These are great. Get a multi-meter or volt-meter as well. Sometimes they don’t “light the lightbulb” since the wind-power is too high.

Conforme à mes attentes

These are quite small and weak, they can only run the small fans that are sold with.

Work Great Thank-You

J'ai est testée jusqu'à 15v 2A au départ on aurais dit qu'il allais tous mourir j'ai vue des éclair bleu sortir et un son aigu comme un sifflet qui casse les oreilles. J'ai donc continuer en poussant le pignon central tout tournais encore malgré tout ça avec unpeu difficultés. Apret quelques min a persévérer il ce son tous exactement rôder de la même façon et ne prenais que .04A a vide a tourné et offre juska 1A de puissance avant de les freiné. Je les adore 3X plus puissant que des moteur de vibrations de manette de jeux qui étais généralement .3 a .4A de puissance avant de les freiné complet.
