Hmm, my motor spins great when using one permanent magnet (stator) and electomagnet (rotor). But, we are discussing something else - the voltage drop. I am going to measure the voltage of the battery when in a circuit as well as connect a resistor in series.

I don't have any info about the recommended current, but I think the battery can't deliver the required current (~5.5 Amps). Currently I am unable to measure the voltage @ the battery terminals while a part of the closed circuit, but when it's not a part of closed circuit it shows ~4.48V which...

It`s OK. Now it`s time to show my progress...I managed to get it working by winding the coil in the opposite direction (I used a permanent magnet). However, when I connect the stator & rotor electomagnets in parallel circuit, I get ~1V @ the both electomagnets. How can I increase the voltage...

Bump... :)

That`s my mistake. I didn`t include such info. Initially I was following these instructions: http://www.howard.k12.md.us/res/MakingStuff/motor.html" However, when everything was finished, the motor wouldn`t start. I wasn`t sure what was the problem, so now I am replacing the permanent...

Sure, just let me know what kind of info you need... Now I am going offline. Just say what you need and tomorrow I`ll post the info.

The link you provided in the last post *might* do the job... After entering the essential parameters, it counted that my coil has resistance of 0.187 µΩ. (length - 2.1m, wire diameter - 0.5mm). What now? My physics knowledge is not yet perfect, so some help would not do any damage.

Hmm, the site I found the scheme at suggested 50 turns for 6 volts.

Hey, I am making an electromotor. How many turns of 0.4mm/26 Gauge wire should I make so as to run the motor at 9 Volts? (I`ll count the needed wire length assuming that 1 turn of wire = 8.5cm.) Thank`s in advance & please let me know if you need more info... :smile:
