One issue with steppers is they use the rated current constantly, regardless of load.
One advantage however is the stationary torque can be applied constantly to hold in place.
You can get motors with sensors, but they are relatively easy to make with either a slotted wheel or other non-optical types.

Ty. Why are we having that sensor again? What data are we trying to feedback? Ty

 

With any other kind of motor and using a G.B. of the worm and pinion type for e.g., it is not capable of being back driven, so stops immediately on power removal.

Just a simple pulse counter.

 

On power off it should NOT be towable. It should act like a stepper motor where it has power, but impossbile to move until the correct signal is sent. I hope I was clear. Ty

I’m trying to envision a useful garden cart. Does it have a specific function, ie transporting a harvester, applicator, planter, or is it a general purpose follower.

Generla transport of dirt, harvested veggies, tools.

 

I recently picked up a couple of surplus geared automotive seat positioning DC motors, not a great deal of speed but a lot of power in a small package.
Automotive wreckers are a good source.

I agree. Cheap and readily available.
Only problem would be that tow thing, which would make it that much more useful.

One question you haven't answered is how long do you want a battery to last? This is a critical factor in determining all power-aspects and motor ratings...

30 minutes.

A simple coupling engagement/disengagement could provide that function
