AC vs DC Motors
AC vs DC Motors
(OP)
I need to select a 1/2-3/4 hp electric motor to power a large battery powered cart. The cart will have laser scanners to detect potential obstructions and stop the cart as well as controls to synchronize it's speed and movement with the other carts. It will also only need to move for about 2 minutes at a time. I am not very familiar with the benefits of AC and DC motors so I would appreciate any input on the matter.
Thanks
Thanks

AC motors are sometimes preferred - mostly because they do not need much service (no brushes to replace) but with the two minutes operation, I do not think that you will need to change brushes in many years.
DC may not be the latest - but is still around. Mates batteries perfectly and is cheap.

Best bet is to look at the surplus places for motors for project prototyping.

They also get you an automatic band brake.

I guess it would help moving it in when new, and out when it becomes old.
Now I do know of the vibrating couch, but that would not be much good for this application.
There are premade wheel motor applications for use in robot construction.

Back to the OP, my preference would be DC.
