With an output voltage range of 3V-24V and a rated speed of 300-6000 rev/min, this generator is perfect for hands-on learning experiences. Weighing only 50g and requiring no assembly, it’s an ideal choice for both educators and students looking to explore the world of electrical engineering. ## Description This is a 3 phase AC generator, can be arbitrarily connected the two lines can light up the LED lamp bead.This product is suitable for the micro wind power miniature hydraulic hand friction power system, the three-phase ac hair in school Teaching AIDS model.Specifications:Output voltage : 3V-24VOutput current : 0.1A-1ARated power : 0.5-12WRated speed : 300-6000 rev/minThis is a great way to teach or learn about generating electricity or as an experiment starting place for larger projects. Review: Excelente! - Excelente! Review: Small, but mighty (for its size :-) - This thing is smaller than I expected, but if you look at the desertcart page carefully and compare with the LED, you can estimate its size. Or, look at the photo here. I tested it this evening with another product bought on desertcart (a 3-phase motor controller from Sydien), and was able to get the CrocSee Micro 3 spinning nicely. But only after feeding the controller with 12 to 15VDC. Lower than that and I could not get it to spin up and sync with the Sydien controller pictured. Used as a generator, it also works, of course. Comes with an LED plugged into two of the three pins on the connector. If you spin the shaft quickly with your fingers, it nicely lights up the LED in a pulsed fashion. Not terribly bright, but it seems to have a lens to focus and is fine for indoor observation. Unloaded, I measured about 2V AC (peak) with a quick finger-spin. With my DMM, I seem to read around 2K Ohms per winding - but that varies (maybe due to AC noise picked up by the coils from the room lights?). So don't expect much current from the thing used in generator mode. 2V and 2K is 1mA at this speed. 10 times faster and I would expect maybe 10 mA - which seems consistent with the kind of numbers I got when monitoring the full current when operated as a motor (about 30 mA at 50 RPM). Of course Safety should always be considered. You don't want a big high-powered, high voltage, high current device for teaching and experiments. (All my motor experiments on the CrocSee Micro 3 used a low-voltage (< 15V), wupply with current limit) Your mileage may vary of course - but for a nice little motor/generator intended for experiments and as a teaching age, it satisfied my needs - especially at the price ! ## Features - This is a Micro 3 phase Brushless AC Generator Model - This is a great way to teach or learn about generating electricity or as an experiment starting place for larger projects. - Output voltage : 3V-24V; Output current : 0.1A-1A; - Rated speed : 300-6000 rev/min; Rated power : 0.5-12W; ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0722Z4PX5 | | Age Range (Description) | Kid | | Age Range Description | Kid | | Battery Description | No batteries required | | Brand | CrocSee | | Customer Reviews | 4.5 out of 5 stars 579 Reviews | | Educational Objective | Learning about electricity generation and related concepts | | Is Assembly Required | No | | Manufacturer | CrocSee | | Manufacturer Part Number | CR71207 | | Material | Silver | | Number of Items | 1 | | Number of Packs | 1 | | Size | Small | | Theme | Science, Physics | | UPC | 711463671903 | ## Product Details - **Size:** Small - **Brand:** CrocSee - **Theme:** Science, Physics - **Age Range (Description):** Kid - **Material:** Silver ## Images ![Micro 3 Phase AC Mini Hand Brushless Motor Generator Model Experiment Teaching Aid - Image 1](https://m.media-amazon.com/images/I/61tdQvF2MAL.jpg) ![Micro 3 Phase AC Mini Hand Brushless Motor Generator Model Experiment Teaching Aid - Image 2](https://m.media-amazon.com/images/I/61idXHZ2-YL.jpg) ![Micro 3 Phase AC Mini Hand Brushless Motor Generator Model Experiment Teaching Aid - Image 3](https://m.media-amazon.com/images/I/61z+geBaz-L.jpg) ![Micro 3 Phase AC Mini Hand Brushless Motor Generator Model Experiment Teaching Aid - Image 4](https://m.media-amazon.com/images/I/51vANAcKvYL.jpg) ![Micro 3 Phase AC Mini Hand Brushless Motor Generator Model Experiment Teaching Aid - Image 5](https://m.media-amazon.com/images/I/51M9s+cG1BL.jpg) ## Questions & Answers **Q: Do you know which gears would fit on the axle?** A: If you need to drill out a hole for this shaft, get a number 32 bit (2.95 mm). Fits like a glove. **Q: Is there a diagram available showing how the stator windings are configured?** A: No diagram, but I can tell you this: it's 6 pole, consequent wound, star (Y) connected. **Q: This device is called a three-phase gen. what frequencies can i obtain from it? i'm interested in 60hz. how clean are the ac sinusoidal voltages?** A: Forget it. It's a toy the size of your thumb. Waveforms are not sinusoidal, frequencies depend on how fast you spin it. **Q: do you have the model number of the generator to simulate in software? id like to see if it is appropriate for my need.** A: No I do not. But, google for tutorials online. You might find some similar models. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente! *by J***. on 23 January 2026* Excelente! ### ⭐⭐⭐⭐⭐ Small, but mighty (for its size :-) *by O***T on 15 June 2019* This thing is smaller than I expected, but if you look at the Amazon page carefully and compare with the LED, you can estimate its size.
