Hi there, I am considering a building for a slow moving EV and have a couple questions if someone doesn't mind.
Background
- I want to use brushed DC motors to drive each wheel separately for a simple drivetrain. Probably a geared motor stepping down again with chain and sprockets.
- Tank style steering
- I expect my wheel base to be quite big - 2m wide, but vehicle only 1.5m front to back
- To keep cost low I am thinking a rigid frame
- It is to be remotely controlled - no operator on the vehicle
- The intended use case is usually fairly flat ground with occasional awkward drains to pass through on an angle which means one wheel would go off the ground which leads to my questions.
Questions
- Can I use a 2 channel motor controller to drive 4 same sized brushed motors successfully? I.e. Just wire up left both left side to output and they should get equal current.
Following on:
- What happens if one wheel lifts off the ground? Is it as I expect - wheel of the ground will spin freely, and load double on the remaining wheel?
- Are there any examples of these types of vehicles about?
