Re: Motor Driver Selection

Because of the 23A rated current at 24V, I would tend to go with the 40A controller over a 20A.

Motors tend to have current spikes when starting and reversing direction. The added robustness of the 40A controller may save you from having to replace speed controllers if currents exceed 20A.
