can you please tell me what part is this?
some transistor or?
Thanks
2 Stef Stuntpiloot: measure how many meters are there in lets say 100 windings of your motor,
then measure the resistance of that part of wire.
you aim to about 10-14 Ohmhs, to keep the drivers cool.
then you do the math, 1 phase is 4 poles,
resistance on driver is between 2 phases,
so it means 8 poles,
so it means you need to have 14/8= 1.75 Ohm per pole of your motor.
then you calculate how many wire you need to get it, in meters, from first measurement.
then you can count how many windings that is easily because at first, you wrapped 100 windings for test, and you know how much cm was in it.
