Comparing one of a motor with two of the same motor with the same overall drive ratio - regardless of how the connection to the wheels is mechanically arranged - is doubling the amount of motor. That certainly changes the performance (including doubling the total torque available), but I don't know why that would be assumed to reduce total current demand.Also, I am considering a dual motor setup (not connected to each other, rather one motor for each side of the rear axle). My understanding is that this would give me more torque with less current. Is this correct? Is the extra cost worth the performance gains?
