After 2 minutes of battery life, the batteries were warm around 40 degrees Celsius. A motor without iron cores is very inefficient - most of the energy is converted into heat. With core in the coils, the energy is converted into a magnetic field and also the coils are much less heated.

they are laminated, well the wires are anyway. about winding the armature backwards, depends on your design. sometimes its good sometimes its not, depends what you need.

Another brilliant project :)

That's a universal motor, meaning that it runs on AC or DC. On AC, the stators fluctuate, but so does the power to the commutator, and so it evens out how the relative polarities of the rotor coils still fluctuate as though still running on DC. Try running it on a small power transformer.

Always wondered how it will respond if you spin it in the opposite direction, and how they always return to their normal spin!

your video is the best. onya grain. :) "simplEST" motor!

A rotor made of permanent magnets and a coiled stator is a superior design, as no commutator is required, which means less friction and wear.

Would switching on and off the outer coils make it run better? (because of electrical difference, instead of just constant dc.) this is happening on the central coils, but would it go better if you switched both on and off? - it would still need the spin start tho- before it starts relaying.

@@KokoroDenshin For efficiency, the cross section of the winding does not play a role. Or rather: more voltage - more turns and thinner wire, less voltage - fewer turns and thicker wire.

The actual efficiency will be determined by the design and materials: bearings, molds, brushes, etc. In the case of non-permanent magnets, the material and design of the electromagnet cores will play an important role.

Cool proyect, But If you say that 100 turns produce 10A, 200 turns will produce 5A? (Increase turns, and reduce the diameter of wire reduces the current) Ah, hm the coils can be replaced by two magnets?...that's all...thanks

@grain-diose

Yes, if the coils have more revolutions, the current is less, since the inductance of the coil increases, and accordingly the resistance increases accordingly. The voltage here is constant, but the current is interrupted, so here the inductance resistance works just like in alternating current. But your assumption is incorrect, therefore, the resistance not only on the number of turns but also on frequency, coil diameter, wire diameter, coil length, number of coil layers, winding method. In a word, you can theoretically calculate everything, there is a program for calculating the coil inductance, but it will be approximately, and after that you need to determine the current. Better not even try it. :) That is, I will not even tell you approximately how the current will change if you change 100 turns per 200 turns. About the replacement of stator coils with magnets, the answer is unambiguous: magnets are much simpler and more efficient! This option without magnets and cores I did as an experiment only. But the efficiency of such a motor is very low: large consumption and low recoil. The most effective of my options is here - kzread.info/dash/bejne/pWeKvLCalZzQetI.html In general, this option is used in many DC collector motors.

I can be wrong, but I think in this case you need 4 coils to do. As far as I understand, the stator and the rotor are better to have a different number of coils for a better independent start. But for speed, it is not the number of coils that is important, more the current in these coils. That is, there must be a thicker wire and fewer turns. Of course the battery should give a lot of current too.
