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.
is it necessary to be laminated ? your cores are not laminated and yet the motor spins and it's very powerful. can someone build a powerful(practical) motor with a solid core without laminations ? also is it necessary that the coils in the armature to be wound in opposite directions ?
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.
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.

nah im wrong... i looked it up - its just constantly there. unless its a little more powerful when it first touches, but i doubt it - so it is a bad speculation.
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
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 - ruclips.net/video/s3VZNae9jJo/видео.html In general, this option is used in many DC collector motors.
@@stevenburton4966 Nope, DC will also generate a magnetic field, with AC the north and south alternate since the voltage is alternating, you use AC for a transformer, an electromagnet will work on DC
You can test it out by winding some wire (around 50 turns) on a screw and connecting both ends to a battery [ + to one wire and - to the other wire] (batteries put out DC) and try to stick paperclips to it
@@EdwardTriesToScience okay, so only the changing pulse can induce a current in another coil for a transformer, but dc can create a magnet with static poles?
Everything happens the opposite: electricity produces induction currents that move the rotor of the motor. But without iron cores, the motor is very inefficient, its efficiency is very low. This motor takes a very large current and heats up quickly. If you want to do, I recommend this model to you - ruclips.net/video/s3VZNae9jJo/видео.html
Because i was thinking to build non-permanent magnet generator, looking at how car alternator design, the coil to magnetize the rotor used very thin copper wire compare to the stator coils.
@@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. Accordingly: a) less current, b) more current. As a result, both options have equal power. 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. In general, standard motor designs have long been developed, can be studied and used.
I think you should use thinner wire with more turns. That wire is too thick to such low voltage suplly. Can you please send the details about the wire conections?
could it be possible to turn this thing into a generator(since you are using electromagnets you can probably feed a part of the generated energy back into them and extract the rest)?
@@kenzostaelens1688 It is possible, but they are complicated to self-start: You must first INDUCE voltage in the coils from an outside source to create a magnetic field, otherwise there's no magnetic field and you're just pointlessly spinning some non-energized coils past eachother without them interacting in any way. It's been a while since i've read about this sortof thing, but i believe this is what happens in a "switched reluctance generator". Or at least it's an adjacent concept?

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.
hey there can somebody explain what will happen if we increase the number of turns of a coil in a motor i:e from 20 turns to 80 turns? i mean will i rotate fast? or will it will have more torque??
I think it gets more torque because brushless motors have higher KV (rpm per volt) and low torque with weak magnet and low KV and high torque with strong magnets.

It is ineffective, especially without an iron core. But more often motors are made with electromagnets, look at the motor of your electric drill.
the current problem is with the Commutator. Too much friction is going on.
