DC brushed motor angle

Hi!

I’m using Pololu Dual MC33926 Motor Driver Shield for Arduino, with brushed DC motor. I’m wondering (wasn’t able to find out how) if I can get the position (angle) of motor. I know it’s probably task for stepper, but need to do it with dc, if tere is a way.

Thanks!

I guess you'll have to use encoder or magnetic encoder of some sort. This board seems not to have any feedback except for current.

There's no way from just the motor itself, so an external shaft-encoder is needed.

Even steppers don't give you position, but will hold position reliably if not overloaded, so that once calibrated you just remember the number of steps.

Its common to use a motor with two shafts for encoders - gearing one end, encoder on the other.

It sounds like you need an ABSOLUTE ENCODER...
