The New Etek-R with AX2560 or AX2860

Will the AX2560 or AX2860 Dual Channel ESC (60V versions) handle the new Etek-R motor on each channel? FYI The Etek-R peaks at 150amps

If you can stay under the 150A, the controller should be able to handle it. However this motor will draw several hundred of Amps when stalled. The controller will not be able to handle such conditions, should they occur.

So the surge rating wouldn't handle the stall? What exactly is considered a stall and what may cause one?

stall would be if the motor is stuck. It can happen when motor starts with little power applied to it. The motor would then consume huge amount of current until it starts going. Under normal condition, this lasts only a very short time, but should it last a few secs, there could be serious damage.

We dont have direct experience with the etek motor but we know of some customers who used it with our controller. I am aware of at least two cases where we had problems. Both were heavy machines with tank-style tracks in steering. These have huge friction when turning the robot, with the motor often in near-stall condition. A more traditional drive train may be ok.

Well i had planned to have tank style steering but was going to use 4-tires spaced fairly close together instead of tracks, does that make a difference? I would use the mixing feature of the esc to turn.

Oh, i would also gear down with chain drive.
