## Overview

Thames & Kosmos Motors & Generators is an educational STEM kit featuring a transparent electric motor that doubles as a hand-crank generator. It allows users to visually explore the relationship between electricity, magnetism, and motion through hands-on experiments guided by a comprehensive 60-page full-color manual. Designed for quick assembly and practical learning, this kit is perfect for budding engineers and curious professionals alike.

## Description

Features: Electric motor is made of transparent plastic to show the inside components. Set up the motor to run on battery power and learn how a motor works. Reconfigure the device to work in reverse as a hand crank electric generator. Experiment with magnets to learn about the force of magnetism. Magnetic fields relate to electric current. Build simple circuits consisting of the motor or generator, wires and a light bulb to learn about the flow of electricity. Learn about gears and drive-trains. Effectively convert kinetic energy into electrical energy and back again. Color and finish: Full color, 48 page manual guides experiments with step-by-step instructions.

Review: Cool stuff !! - Very good for my kids (14 years old girl and 9 years old boy) to have practical understanding of very basics of electrical engineering. I have helped them to assemble and able to show them what is gear ratio, what is commutator brush DC Motor and what is DC generator with the kit. Also a nice feature when you remove the red and blue magnets then neither the generator generates electricity nor the motor runs. The toy is not that you build generator or motor on your own hand. Rather it is assembled rotor with 3 commutators and two terminals which can be mounted with plastic gears and permanent magnets to act as BDC motor or generator. The assembly is very easy and it takes maximum 5 minutes for me and 10 minutes for my kids.

## Questions & Answers

**Q: ?right for boy age 8 and good at building**
A: I think so, we got a bunch of these sets (because they are modular and can work together to build more complex stuff) for our 8, now 9 year old.  He is an expert at Legos--building the 14-16 year old sets.  He found this fun and it is still on the front of the toy shelf.  T&K manuals are like mini-science books.  They have been great to re-teach the mom too :)

**Q: Seriously... gender - boy!?!  really!? girls need to know about science and engineering, as well! the gender description should be removed!**
A: Definitely for Girls, too!  I’m with you there! Amazon needs to know that Electronic learning is not gender specific to Boys and needs to put the Electronic learning category under all genders!

**Q: Does this set turn gears to make other sets parts move**
A: There are 2 gears connected to a generator through a hand crank.  There is a clear plastic cover over the gears so you can see how they mesh together as you turn the hand crank.

**Q: Is this compatible with the Thames and Kosmos Electronics learning circuits series of kits as an alternative to the battery compartmentt?**
A: I’m not sure. I didn’t purchase the circuits kit.

### ⭐⭐⭐⭐⭐ Review
*by S***N on 29 March 2021*

I really enjoyed assembling this kit! It had exactly what I'd wanted -- gears, magnets and coil, and a working mini generator. The kit does do a good job of illustrating the principles involved, and in a manner way more engaging than what is typically used in schools!! Or in my schools, anyway. The booklet was also very interesting. Overall, I think this item would make an excellent gift for an intellectually curious recipient!! As for its compatibility with other kits, specifically electronics, that's a good question! It does mention hooking up more than one generator together, so you ought to ask, because obviously, duh, that would be awesome! Overall, a fun purchase! Definitely giftable in my opinion.
