I have a stepper motor with name tag of 1.2 Amps
not sure if this is per phase or for both phases.
Any way I set the tb6600 at 2Amps in order to get it to a reasonable warm-hot (I still can touchch it comortably)
when I measured the volt across the coil it was 3 volts.
which means I am supplying 1 Amp for each coil.
Is this correct understanding? The tb6600 microstep setting I let it at 200 that means no additional microstepping by the driver.
I measured the resistance of coil A about 3 ohms. (Does this reading make sense as it is very small) while coil B is 3.2 ohms.
Should not both coils be exactly the same?
Any way here is my question
I read so often that stepper motors like high voltage for multiple of reasons, now If the motor resistance is fixed how can I supply high voltage to the motor without exceeding the rated current? I can not cheat ohms law.
So why people talk about supplying 80 or 48 volt to the stepper motor? How that can be done without exceeding the current limit of the motor?
